18 Cut the cords! Wireless charging is here!It seems that my phone always runs out of power at the most inconvenient times (as if there’s ever a convenient time). Like the time my phone ran out of power as I was trying to board a plane with my electronic boarding pass.

20 Going spare: boosting voltage using spare MCU peripheralsWith a few discrete components and some creative thinking, spare microcontroller peripherals can be used to provide a low-current, regulated voltage boost, as Keith Curtis, Technical Staff Engineer, Microchip Technology Inc. explains.

22 Fulfilling the requirements of future EPS systems with the latest microcontroller generation

In ever more new cars the EPS (Electric Power Steering) instead of the classical hydraulic power steering is being used. There are manifold reasons for this: lower energy- that is, less fuel consumption, easier installation in the vehicle, lower fault susceptibility, better adaptability to different car models and last but not least more driving comfort and safety through sophisticated control algorithms.

Microchip announces, from Electronica inGermany, an expansion of its 8-bit PIC®microcontroller (MCU) portfolio, with theperipheral-rich, low-pin count PIC16(L)F161X family. These new MCUs introduceand expand the offering of Microchip’sCore Independent Peripherals (CIP),which were designed to reduce interruptlatency, lower power consumption andincrease system efficiency and safety, whileminimising design time and effort. Theseperipherals also reduce system complexityby eliminating the need for additionalcode and external components.Hardware-based peripherals offload tim-ing-critical and core-intensive functionsfrom the CPU, allowing it to focus on othercritical tasks within the system.

The PIC16(L)F161X PIC MCUs offer theMath Accelerator (Math ACC) withProportional Integral Derivative (PID),which provide completely CoreIndependent calculations, with the capa-bility to perform 16-bit math and PIDoperations. The family also includes theAngular Timer (AngTmr), which is a hard-ware module that calculates the rotationalangle in functions, such as motor control,TRIAC control, or Capacitive DischargeIgnition (CDI) systems. Regardless ofspeed, the AngTmr allows recurring inter-

rupts at a specific rotational or sinusoidalangle without using the core’s computa-tion. The CIPs can be configured to per-form a host of given functions that increaseexecution speeds and decrease softwarerequirements. Offloading these functionsfrees up the CPU do other tasks, consumesless programme memory, and reduces theoverall power consumption of the MCU.In addition to the MATH ACC andAngTmr, the PIC16(L)F161X features sev-eral other peripherals designed to easeimplementation and add flexibility of vari-ous functions. The 24-bit SignalMeasurement Timer (SMT) performshigh-resolution measurements of the digi-tal signal, in hardware, resulting in moreprecise and accurate measurements. This is

ideal for speed control, range finding andRPM indicators. The family also includes aZero Cross Detect (ZCD) module, whichcan monitor AC line voltage, and indicatezero crossing activity, simplifying TRIACcontrol applications by greatly reducingboth CPU demand and BOM cost. In com-bination with the new 100 mA, high-cur-rent I/Os, the proven Configurable LogicCell (CLC), and I2C™, SPI and EUSART forcommunications, this high level of integra-tion helps to speed design, eases imple-mentation and adds flexibility.

Designers can now perform secure wireless data communica-tion on their embedded systems without needing the hostmicrocontroller, but by simply using a single MAX66242DeepCover® Secure Authenticator from Maxim IntegratedProducts, Inc.The MAX66242 secure authenticator is an advanced tag thatcombines a wireless NFC/RFID interface with an I2C interface.

Designers can now collect vital system data from portabledevices even when the main energy source on the masterdevice is not functional. The I2C and wireless RFID/NFC interfaces make it highly flexi-ble and scalable for a wide range of applications. TheMAX66242 is especially useful for applications that requireadditional external functionality, but do not have the space toplace a connector. Ideal applications include secure, wirelesstransfer of medical data or asset tracking.The MAX66242 enables wireless, contactless data collectionbetween a host and slave device. The integrated, provenSHA-256 cryptographic engine provides symmetric chal-lenge-and-response authentication based on a secret key fordata downloads.Needing no separate controller to write data, theMAX66242’s I2C interface port can operate as a master portor a slave port for secure data exchanges. The MAX66242comes with multiple memory programmable options whichlet a user configure a secure master/slave system and setusage limits using the EEPROM emulation mode to createnonresettable counters. Designers can also use theMAX66242 to set up easy and intuitive WiFi® or Bluetooth®connections as a means to securely storing the pairing codes.It then provides security for access control, asset tracking, sys-tem alert/wakeup, and authentication of medical sensors forthe secure transfer of personal data.MAXIM INTEGRATED www.maximintegrated.com

Master and Slave DevicesThe “self-driving car” concept has captured the world’s imagination,and today’s advanced driver assistance systems (ADAS) are catalyz-ing this revolution. But the enormous opportunities these marketspresent come with significant challenges that must first be solved.Freescale Semiconductor is propelling the industry forward byaddressing two critical speed bumps on the path towardautonomous driving – the lack of open standards for ADAS systemdevelopment, and the common-but-empty premise that consumerfocused silicon solutions are safe enough for critical autonomousautomotive applications.

Freescale announced it will soon introduce an OpenCL (OpenComputing Language)-based automotive development environ-ment engineered to open the market for car OEMs and tier-onesuppliers alike to bring advanced driver assist and other ADAS tech-nologies to a wider range of vehicles, faster. The company also calledon tier-one ADAS system providers and their suppliers to renewtheir industry-wide commitment to automotive safety via the designand deployment of highly secure embedded semiconductors builtfrom the ground up to meet and exceed automotive-grade qualityrequirements.The Democratization of ADASResponding to the current lack of open standards, and to reverse thetrend toward closed, proprietary ADAS systems which inhibit devel-opment and stifle design innovation, Freescale will offer an OpenCLdevelopment environment for ADAS systems targeting Freescale sili-con and engineered to reduce R&D overhead – effectively democra-tizing the ADAS development process. OpenCL is an open, royalty-free standard for cross-platform, parallel programming. It greatlyimproves speed and responsiveness for a wide spectrum of applica-tions in numerous markets. OpenCL is an open standard maintainedby the non-profit technology consortium Khronos Group.Automotive Grade from the Ground UpDespite the increasing publicity surrounding them, autonomousvehicles will simply not exist on a commercial scale without safe, reli-able and secure solutions. Freescale believes that the assertion thatconsumer-oriented silicon solutions designed to enhance gaminggraphics or run smartphone apps are safe enough to ensureautonomous driving-quality and reliability in automotive applica-tions presents significant risk to the automotive industry. Such claimsare perpetuating a hype cycle that is dissociating reality from thevision of self-driving technology.FREESCALE SEMICONDUCTOR www.freescale.com

DESIGN INDUSTRY 4.0

“A business that does not embrace theshift towards Industry 4.0 will soon be likethe hands-free kit in a car without aphone connection – it's there, but it's cutoff and therefore useless”, said AndreasMangler, Director Strategic Marketing andCommunications at Rutronik, outlining thefuture. “Dinosaurs do not survive; we'veseen that often enough.”

The drive to increase efficiency is ever pres-ent. What's new in this area is the trendtowards individualization – whether it'sindustrial PCs, cars or muesli, customerswant their products exactly as they need orwant them. Providers such as the drugstorechain dm demonstrate how it is done – usingan app or software, customers create theirown customized photo album, poster, can-vas picture, cellphone case or shower gelwith their own photos. dm even collabo-rates with Deutsche Post to enable cus-tomers to add their likeness to a stamp. Thedata is uploaded via an internet connection,and a few days later, the finished productarrives on the customer's doorstep. “That'sIndustry 4.0 down to a T”, said Mangler.

Many other businesses have also perfectlyadapted to the trend towards individualiza-

tion – but the scalability of their processeshas suffered as a result. Industry 4.0 promis-es to solve this dilemma by producing cus-tomer-specific solutions under mass pro-duction conditions, but many businesses stillhesitate to establish the smart factory as acore element of Industry 4.0. There are twomain reasons for this: firstly, the costs, andsecondly, the fear of exposing intellectualproperty (IP), thereby making it vulnerableto loss.

Industry 4.0 Needs a Different Cost PerspectiveImplementing Industry 4.0 requires invest-ment – there's no doubt about that. But inreturn, it generates long-term savingsthrough increased efficiency. Such savingsare generated at other levels though, whichis why they are frequently overseen. Thecurrent profit center-based approach tocompany management only considers spe-cific unit or personnel costs in quarterly timeblocks, meaning that a perspective of theoverall costs, in which all processes areincluded, is missing. The situations that thiscircumstance leads to are sometimesgrotesque. An example – a developerdesigns a mature, forward-looking technolo-gy, but it is not approved by the purchasing

division due to excessive unit costs.However, the cheaper components aremanually taken, recorded and moved sever-al times during the route from the receipt ofthe goods to production. The process costsincurred here consume the previously gen-erated savings back or even exceed them –even though the purchasing division isunaware of this. This means that expensivemanual processes remain in place, as theyostensibly cause lower costs than automa-tion of the process. “This approach pre-vents both cost savings and innovation”,summarized Mangler. Examining the situation from a total cost ofownership perspective on the other handaccounts for the actual total costs incurredthroughout the entire process chain, fromdevelopment to purchasing and logistics.This enables each business to determine forthemselves whether it would be worthimplementing Industry 4.0, in which divi-sions and to which extent. “Not every busi-ness can become a full smart factory. Thetrick is to find the right balance betweenthe technology and investment on theone hand, and the purchasing divisionwith the purchase price and the costs ofthe automated processes within the logis-tics chain on the other.

“Industry 4.0 Has to Prove thatIt Is Worth the Money”

The technological basis for Industry 4.0 has long been available – but what is oftenlacking is the courage to make it a reality. Promises of efficiency increases, evenwith smaller quantities and custom production of single products, are linked tocosts and security risks. But for most companies, there is no alternative.

DESIGN INDUSTRY 4.0

So businesses will not always incur anenormous outlay in one fell swoop. Takingthe first step by establishing an EDI con-nection with the distributor or supplier isusually sufficient – a very well-establishedtechnology”, explained Mangler. “This doesmean though that Industry 4.0 needs toprove cost of ownership for the relevantsub-processes in order to demonstratetheir benefit.”

Safety Requires ExpenseAside from the investments in necessary sys-tems, there are also other costs required fornecessary safety measures. The fear of loss of data, IP and control iswhich makes data security an extremelyimportant – if not the most important –aspect. “Big data” – the collection, analysis,storage, processing and management ofhuge amounts of data – is an enormous chal-lenge. “The winner will be whoever cansuccessfully and securely collect data andensure its security to the greatest extentpossible”, said Mangler. Technologies forthis are already available at different levels,for hardware, software developed “close tothe metal”, firmware, and all other softwaresystems based on high-level languages.

“These aspects must be accommodatedwhen selecting components, becauseIndustry 4.0 is dependent on robust sys-tems through hardware in particular”,explained Mangler.

And robustness is not just required for com-ponents. Operator control systems alsoneed to be robust, and in this respect thereare also already solutions available. The useof system redundancy, for example byenabling both touch and motion control,allows data to be compared and manipula-tion to be prevented.

“Of course, this means more expense forbusinesses, but the long-term value creat-ed by Industry 4.0 through increases inefficiency and the resultant continuedcompetitiveness balances this expenseout in the medium and long-term. Thismeans that many businesses don't have achoice in the matter – either they followthe trend, or they'll be out of the picturesooner or later”, said Mangler, sharing hisassessment. “We're available to assist youas a technology partner, supplier, adviserand contact.” Rutronik laid the foundationsyears ago to enable it to offer its customers

everything now that they need for Industry4.0. These are mainly those componentsthat are now bundled under RUTRONIKEMBEDDED, as well as appropriate supplychain solutions. “We were investing in Industry 4.0 longbefore the term even existed. That's whywe are convinced that we are an Industry4.0 driver”, commented Mangler.

RUTRONIK EMBEDDED encompasses theproduct segments of embedded boards,storage, displays, wired and wireless com-munications technology, auto ID compo-nents, sensors and actuators as well as spe-cific peripheral components. The underly-ing basis of Industry 4.0 is networking –communications technologies. This basiswas established by Rutronik many years agowith the establishment of the WirelessCompetence Center, ensuring that all stan-dards and technologies are present in theportfolio and providing the company pos-sesses with many years of extensive in-houseexpertise. “We were one of the pioneers inthe wireless segment back then, which ispaying off today”, explained AndreasMangler. “We made such an advanceinvestment in our logistics division.”

Rutronik was one of the first distributors todevelop concepts and establish the under-lying technological conditions for creatingmodular, fully automated and linked logis-

tics processes that directly integratesRutronik into the process landscape of itscustomers and suppliers. As a result, allthose involved benefit from a highly effi-cient procurement process. “Industry 4.0 isessentially the perfect opportunity for us,

because we have united our entire prod-uct range under this principle.” For each sub-task within the fully-realizedIndustry 4.0 business at Rutronik, there are

relevant specialists and processes available –RFID and wireless experts with their solu-tions ensure that products can be uniquelyidentified and guarantee that they can betracked within the Rutronik logistics process.It also enables all deliveries to be tracked

along the supply chain, thereby ensuringthat they can be located at all times. This issupported technologically by the GPS andwireless specialists.

DESIGN MCUs

The new ARM Cortex-M7 core provides agreat example of how semiconductor manu-facturers and their partners are addressingthe challenge of size constraints. It deliversan impressive 2.14DMIPS/MHz.

As I write this blog, there are no specificsabout the size of this highest performanceCortex-M-class core on the ARM website,but if it is anything like the Cortex-M4core, itshould be a game changer in delivering theperformance/mm2 to meet the growingdemands of consumers for their portabledevices. As a point of reference, if you arelike me and purchased your first computerin the 90s it may have been a processor thatran at 200MHz with < 2DMIPS/MHz. Futureembedded solutions from Freescale that uti-lize the Cortex-M7 core will deliver similarprocessing capabilities in a fraction of thearea that was needed. There is more thanMoore’s law at play here; thanks ARM!

Kinetis MCUs:Meeting the challenge of wearabledesigns today and tomorrow

In my previous blog I focused on the functionality of the new ARM® Cortex®-M7core. I wrote of the higher processing throughput, new micro-architecture, cachefor the memory interfaces and the advantages of ARM Cortex-M core compatibility.There is another dimension to meeting the challenge of today’s IoT applicationsthat I failed to mention. This is around meeting the challenges of size and space.As electronic devices become more assimilated into our lives, the deeply embeddeddesigner has to consider the aspects of fit and form to be as important as function.This is becoming more apparent everyday as we see the stylishwearable designsthat are hitting the marketplace just in time for the holidays.

Besides the processing to support an immer-sive user experience on an easy to wearembedded device, there are other aspectsof the Kinetis MCU portfolio, Freescale’smicrocontroller product line based on ARMCortex-M cores, which address space con-straints. The Kinetis mini MCUs have propa-gated chip-scale packaging across a widerange of solutions of varying memory size,I/O and processing capabilities. Chip-scalepackaging allows area to be optimizedbecause the size of the package closelymatches the physical size of the microcon-troller. This type of package allows megabitsof non-volatile flash memory and plentifulcommunications peripherals to be accessiblein a package size that is close to 5mm x 5mm.Kinetis minis solutions range in size from theworld’s smallest ARM powered solution at1.6mm × 2.0mm to highly integrated solu-tions at 4.8mm × 5.6mm. Having a widerange of Kinetis minis products allow you,the embedded designer, with the opportu-nity to find the right functionality per mil-limeter squared for your applications.

In addition to packaging, Kinetis MCUsdeliver integration that when utilized allowsboard space to be optimized. One exampleis around the USB sub-system on Kinetisdevices. As the USB standard requires 3.3Vsignals, Kinetis devices that integrate USBcontain a 5V to 3.3V regulator in order topower the USB sub-system. This featurereduces the need of an external IC in somecases. In addition, on some of the latestKinetis devices, an external crystal is nolonger needed for the USB device mode. Aninternally generated clock can be utilized formeeting the clocking requirements of a USBdevice. Features such as these expand thesize benefits of a Kinetis device to the sup-porting infrastructure that must be placedaround the MCU.Another key aspect of many wearabledevices is around sensing. Many sensorsrequire digital interfaces, such as I2C, but insome cases, an analog interface is needed.Most Kinetis devices contain a very capableAnalog to Digital Converter that may beused for interfacing to a wide range of sens-

ing devices. It can provide >12bits of accu-racy on a number large number of inputpins. On some Kinetis devices there is moreadvanced integration of higher resolution(up to 24bit Sigma Delta) and opamps orPGAs for signal conditioning. Integrating thisadvanced capability reduces componentcount and creates lighter and easier to wearend devices.The Kinetis MCU portfolio provides a widerange of tools to meet the challenges of lim-ited space. Selecting which Kinetis MCU hasthe right integration for a specific wearabledesign greatly depends on the goals of theend application. As the wearables use case isdiverse and evolving, it is hard to say exact-ly which features will be utilized the most. Isa Kinetis MCU the right fit for your nextdesign? Try it on.

DESIGN WIRELESS

The point is that we rely heavilyon our mobile devices to pro-vide information and simplifyour daily lives, creatingincreased dependency on them.For this relationship with ourmobile devices to be effective,they have to remain poweredwhile we use them. However,opposing forces, such as theneed for increased feature den-sity, larger screens, and morewireless connectivity strain thesedevices’ power reserves. Beforethe advent of smartphones, atypical mobile phone could eas-ily last a full day on a singlecharge. Today’s feature richsmartphones, most likely will notremain powered even for a halfday under average use. Whilemanufacturers design ever larg-er batteries for their mobilephones, this benefit is effectivelycanceled out by new andenhanced features. New meth-ods of dealing with short batterylife have to be addressed.

Wireless power has the poten-tial to help alleviate dead bat-tery conditions, especially in sit-uations where it matters most –in public spaces and while we’reon the go, such as in the car.Wireless power transmissionwas first demonstrated byNikola Tesla in 1893, as he trans-ferred energy wirelessly to lightphosphorescent lamps. While his experiments obvious-ly did not lead to the prolifera-tion of transmitting power wire-lessly, the foundations for wire-less power were built over 100years ago. It wasn’t until the late2000s that wireless powerwould again be a mainstreamtopic of discussion. Companies began commercial-izing products that could wire-lessly charge mobile devices. Inthe beginning, these productsconsisted of bulky mobilephone adaptor sleeves whichcontained a wireless chargingreceiver.

Cut the cords!Wireless charging is here!

It seems that my phone always runs out of power at the most inconvenient times(as if there’s ever a convenient time). Like the time my phone ran out of power asI was trying to board a plane with my electronic boarding pass. Or that time whenmy motorcycle had mechanical failures and left me stranded on the side of theroad with a dead phone and no way to contact a friend. Several times, I’ve beenon road trips and used my phone as my navigation system, only for it to die at acritical moment when I needed to know which highway exit to take.

The wireless charging transmitter had to bebought and would only work with certainwireless charging receivers. Soon, severalcompanies were commercializing their ownunique wireless charging products, none ofwhich were interoperable. In 2008, the firstorganization was formed to try and developa common wireless charging standard. TheWireless Power Consortium began to devel-op a standard it called “Qi”, pronounced“Chee.” The goal was to create a unifiedstandard where member companies coulddevelop their products for all types of mar-kets, and for which the mandate was inter-operability. Fast forward to 2014, and themarket now has three competing standards,and a mobile phone market with a high rateof adoption. The need for bulky add-onsleeves has decreased, while more and moreOEMs integrate the receiver technology

into their mobile devices. While the com-peting standards have created some tempo-rary market disruptions, a unified standardwill eventually provide a clear path fordeploying wireless power technology.For this technology to be truly transforma-tive, though, wireless charging has to be per-vasive and available everywhere. This nextphase means that the public infrastructurenow must adopt wireless charging stations inorder to provide the full benefit this tech-nology offers. Airports, restaurants, coffeeshops and hotels will all one day offer wire-less charging stations for their customers.Since mobile devices will already have thetechnology embedded, charging willbecome as trivial as placing it down at acharging station. This, in turn, will promotewhat I call opportunistic charging behavior.Users will have apps on their phones that

guide them to the nearest charging station.No matter where we are, we will be able toreceive some power for our mobile device,thereby avoiding dead battery conditionsall together. Whether at a restaurant or sit-ting on an airplane, placing your mobiledevice down on a wireless charger willbecome second nature.

Freescale helps to redefine this mobility bydesigning innovative solutions for bothautomotive and consumer wireless chargingmarkets. By creating flexible solutions, weprovide wireless charging product designersthe ability to create new ways to solve theproblems facing mobile users. Just as WI-FIgrew into a ubiquitous technology overtime, wireless power is expected to followsuit in the foreseeable future. nwww.freescale.com

Going spare: boosting voltageusing spare MCU peripherals

With a few discrete components and some creative thinking, spare microcontroller peripheralscan be used to provide a low-current, regulated voltage boost, as Keith Curtis, Technical StaffEngineer, Microchip Technology Inc. explains.

With the trend towards higher integration,more peripherals are being packed intoeach microcontroller. However, when thekey peripherals have been mapped, manydesigners find that other peripherals aresimply left unused. With a little creativethinking and a handful of low-cost discretecomponents, the right mix of spare periph-erals can be used to boost a 5V supply volt-age to a low-current, regulated 15V.

The most obvious solution to boosting thesupply would be to go to the expense ofusing an inductive boost. Another optionwould be to use a capacitive voltage doubleron the raw supply, but this would add anoth-er IC onto the board and also make the volt-age susceptible to sagging under load.

A more creative approach is to harnessunused peripherals on the microcontrollerto create a simple capacitor-based voltagemultiplier. Using the H-bridge-outputmodes of the microcontroller’s PWM,together with its voltage comparator,bandgap reference, and a few analogue-to-digital converter (ADC) channels, plus a fewexternal capacitors, resistors and diodes, it ispossible to create an enhanced version of avoltage doubler or charge pump. The origi-nal versions of these were used in the earlydays of television when the Villard cascadevoltage multiplier was used to generate thehigh voltage for the CRT.

The microcontroller’s PWM provides a per-fect charge pump, whilst the comparatorand bandgap can be used as a simple feed-back mechanism. Combining the charge-pump-multiplier topology with the PWM

produces a circuit that could generate 18Vunloaded. Regulating the output down to15V is achieved by switching the PWM out-puts on and off, based on voltage feedback.Figure 1 shows that, when the output volt-age is low, the first capacitor is charged forhalf a cycle through the comparator output.The charge is then transferred to the nextcapacitor on the other half of the cycle.After several more cycles, the charge propa-

gates through the capacitors, adding about4.5V per stage. When the output is suffi-cient to raise the inverting input of the com-parator above the reference, the outputgoes low, and the first capacitor does not

charge, preventing any new charge frompropagating to the output.A handful of resistors, capacitors and diodesand a few spare peripherals from a PIC®microcontroller can, therefore, be used toprovide functions which would otherwiserequire the cost of an additional IC on theboard nMicrochipwww.microchip.com

Fulfilling the requirements offuture EPS systems with the latest microcontroller generation

In ever more new cars the EPS (Electric Power Steering) instead of the classical hydraulicpower steering is being used. There are manifold reasons for this: lower energy- that is, lessfuel consumption, easier installation in the vehicle, lower fault susceptibility, better adaptabilityto different car models and last but not least more driving comfort and safety throughsophisticated control algorithms.In case problems occur in the EPS-ECU, only very limited vehicle operation due to missingpower steering assistance is possible. EPS system manufacturers are therefore working toencounter this problem through redundancies and thus be able to offer a fault-tolerant system,which can guarantee at least a minimum of safe operation.

Author: Björn Grothkast, Senior Engineer Chassis & Safety Marketing, Automotive Business Group, Renesas Electronics Europe, Düsseldorf

Maximum functional safety The steering function in the automotivefield is not only important for the life andsafety of the driver but also of his co-pas-sengers, other road users and even that ofthe non-involved passers-by. A sudden fail-ure or a malfunction can quickly have cata-strophic consequences.It is therefore no surprise that in ESP systemsASIL D is derived from the ISO 26262 stan-dard. Thus, in the ECU safety concept, themicrocontroller is treated as the SafetyElement out of Context (SEooC) and is alsodeveloped in accordance with ASIL D usingthe state of the art technology. The samesafety standard of course has also to be

applied to the software.Meanwhile, in the automotive segmentthere is hardly any 32-bit microcontrollerapplication which is not based onAUTOSAR architecture. Even though at firstthe AUTOSAR standard based architecturemay appear to be very complex, this is theonly way to realise an economically mean-ingful platform concept. Thanks to the har-monised system architecture it is for exam-ple - depending upon the project require-ments - relatively easy to add-on or toremove features from the software. Also alarge portion of the proven application soft-ware can be reused while migrating fromone microcontroller generation to the next.A precondition for this approach though is a

comparatively large program memory aswell as up to 400 DMIPS computing power,which is associated with electrical powerconsumption of up to 1 Watt.Car manufacturers as well as their sub-con-tractors are getting progressively aware ofthe fact that even EPS systems are exposedto the dangers like unauthorised replicas,modification of settings and functions aswell as attempted frauds in terms of guaran-tee or warranty. Currently available microcontrollers, devel-oped for EPS systems do not offer anyspecifically protected memory area and nosafe random number generator (TRNG).When an error occurs, most of the present

day EPS systems put the system into safestate in accordance with ISO 26262 byswitching off any power steering support.Especially with relatively heavy vehicles ofpremium segment however, the driving situ-ation in this case can quickly become verycritical, for example, when power steeringsuddenly fails in a curve and the driver is notprepared for that.

Goals for the next EPS generationEPS manufacturers are focussing their effortsnow just on these points: more driving com-fort and safety, lower current consumption,more protection against manipulation andreplicas, and particularly important, contin-ued operation as far as possible even in case

of fault (fail operation).In future EPS systems will also take overfunctions in conjunction with the comfortand safety field (like for example, lane assis-tant, crosswind compensation, parking assis-tant). For these tasks a large amount of sen-sor data is to be evaluated and processed.Whereas in the previous EPS generationsapproximately 384 KB memory size for pro-gram code was sufficient, currently hardlyany EPS systems requires less than 512 KBmemory. Following this trend, for the nextgeneration EPS systems, microcontrollerswith considerably larger flash memory and acomputing power up to 450 DMIPS arerequired.

Lower current consumption and higher computing powerIn contrast to other systems where it is pos-sible to switch between different currentsaving modes, for microcontrollers in theEPS field extreme low current consumptioneven in full operation mode is very impor-tant. The low heat dissipation of the micro-controller is not only supposed to facilitatenew, cost-effective power supply conceptsand thermal designs (like for example, plas-tic housing instead of the costly aluminiumhousing), but will also contribute towardsreduction of CO2 emission of the car lead-ing consequently to lower environmentaltaxes for the car manufacturer.

Microcontroller roadmap for automotive applications with stricter requirements for functional safety (Renesas)


Additionally, for the forthcoming EPS gener-ations the cryptographic protection of com-munication between the EPS-ECU and otherECUs, connected sensors and external diag-nostic devices would be an important issue.

Also, it must be ensured that during updatesin the workshops only the intended originalsoftware from the manufacturer can beloaded. EPS- and car manufacturer expecttherefore not only hardware support forAES calculations but also that a non-deter-ministic random number generator for gen-erating high quality random numbers isimplemented. Cryptographic keys and cer-

tificates may of course only be stored in aspecial memory area which is protectedagainst unauthorised reading and writing.In ideal case, already the semiconductor man-ufacturer would provide each microcontrollerwith a unique, unalterable and software read-able identifier. This would, for example allowidentification of individual ECUs and explicitlyenable functions only for it.

Operational safety goal (Fail Operation)For safety and comfort reasons, it would notbe sufficient in near future that EPS systemssimply switch themselves off in case a fault

occurs. The car drivers and with that also thecar manufacturers expect a reliable systeminstead, that is, a system in which at least thebasic functionality is guaranteed even afterthe breakdown of a sub-system. Also therapid development in the field ofautonomous driving is a clear indication thatreliable EPS systems would become indis-pensable in the coming years.

At system level, this can for example beachieved by deploying a 2 × 3-phasesmotor. Thus, even after total breakdown ofone 3-phase system, up to 50% of powersteering support would still be available inthis way. This reduction in performance isnoticeable in certain situations, still, it is suf-ficient though to keep the car under controland drive it safely to the workshop.

At the microcontroller level it means imple-mentation of such a redundant system sothat both 3-phase systems are synchronisedvery precisely with each other because evenminor deviations in synchronisation wouldput burden on the mechanics resulting inunpleasant driving experience.

One possible solution: Renesas RH850/P1MWith the RH850/P1M microcontroller,already available in sample quantities,Renesas will offer EPS system developers thepossibility to fulfil the aforementionedrequirements of future EPS systems in theeasiest possible manner.

Not only for EPS developers, the effortsrequired for a changeover from one micro-controller generation to the next is an impor-tant time and cost factor. For this reason,Renesas designed the RH850/P1M microcon-troller with the goal of keeping maximumpossible compatibility with its predecessor,the V850E2/Px4. Besides already implement-ed necessary functions in V850E2/Px4 gener-ation for ASIL D systems like, for example,Lock-Step Dual Core (LSDC), MemoryProtection Unit (MPU) and ECCs, many newfunctions have been added in RH850/P1Mmicrocontrollers which are practically indis-pensable for the next EPS generation.

On top, new packages with only 0.4 mminstead of 0.5 mm pin pitch guarantee morecompact ECU design with same functionality.The enhanced 450 DMIPS computingpower and up to 2 MB integrated programmemory allows implementation of very

sophisticated algorithms. The migration tothe leading 40 nm technology in automotivesegment ensures thereby that the perform-ance increase is even supplemented withreduction in basic current consumption toless than 150 mA. In the car manufacturer’s books, this reduc-tion means approximately 75 euro cents lessin taxes for the CO2 exhaust and with thatlower cost under the bottom line.

To safeguard the ECU against manipulationsand to secure the confidentiality and

authenticity of messages exchanged withother ECUs, the RH850/P1M is equippedwith an integrated Intelligent CryptographicUnit (ICU-S). This SHE specification (refer:www.automotive-his.de) compatible hard-ware unit provides a specifically protectedflash memory, local RAM, a hardware ran-dom number generator and an AES-engine.

The protected memory cannot beaddressed directly by the CPU but is rathermanaged by the ICU-S. It is therefore ideal-ly suited for example, as protected place-

ment area for cryptographic keys and cer-tificates. The built-in AES-engine supports128-Bit key, optionally in ECB- or CBC-mode. Additionally, Renesas offers EPS man-ufacturers to provide all RH850/P1M micro-controllers with a fixed, worldwide uniqueand internally readable device-ID.

As it turns out, in the software field, a 100%ASIL D system is neither necessary, nor is itfeasible and justifiable within a commerciallymeaningful framework. Consequently, mean-while in the EPS field the software has bifur-cated itself in safety-critical and non-safety-critical parts. A retroactive effect free interac-tion of all safety relevant modules is a must,so that the functional safety of the whole sys-tem can be guaranteed even in case of a mal-function (freedom of interference).

For the RH850/P1M, an ISO 26262 ASIL Dcapable MCAL is under development.As in case of its predecessor V850E2/Px4,the RH850/P1M field of application will alsonot be limited just to the EPS systems. TheRH850/P1M is suitable for many applica-tions, which have high demands in terms offunctional safety in common. These, besidesthe next generation EPS systems are forexample transmission controls, locking sys-tems, airbags as well as battery managementand charging systems for hybrid and electricvehicles.


DESIGN AUTOMOTIVE

Thanks to modern 40nm technology, RH850/P1Mdevices consume only about ¼ of the power of othercomparable microcontrollers.


Summary & outlookAs described above, the requirements interms of complexity of algorithms, function-al safety, current consumption as well asmanipulation and operational safety areincreasing with every EPS generation.Most of these requirements are clearlydefined. For some others, such as the conti-nuity of operations in case a fault occurs (fail

operation), still different approaches areprevalent today and presumably the mosteligible one of those would establish itself inthe next few years. Next generation microcontrollers which arealready under development like for exam-ple, the RH850/P1M from Renesas will helpEPS developers to fulfil the requirements ofthe future EPS systems.

What are the price advantagesof light color regulation via feedback control?

When looking at color correction or controlsolutions in LED lighting systems - these are

often regarded as an expensive add-on. But actually it is possible to reduce the overall

costs and future maintenance costs of a lightingsystem by using direct feedback solutions. This

article demonstrates how to resolve variousissues LED engineers have to cope with.

Author: Dr. Fred Grunert, Managing Director, MAZeT

The current state-of-the-art LEDs demon-strate a high luminosity intensity but are inan early development-stage when it comesto brightness relations between chip tem-perature as well as aging-effects of the light-emitting layer of LEDs.

TEMPERATURE DEPENDENCE

The dependence of the brightness and thewavelength in correlation to given tempera-tures are known negative issues. Image 1demonstrates the behavior of red, green,blue combinations of a LED light source.Image 1 shows that the dependence of a red

LED is greater than compared to a blue LED.The brightness decreases by almost 40%during temperature drifts of 5°C (41°F) to70°C (158°F). Shifts within the color percep-tion and brightness of mixed light areinevitable. Additionally, the user mustdecide how to calibrate the light source,

depending on the environmental influences(such as temperature or pressure) anddesired output of light color. Especially inlarger projects, consisting of multiple lightsources it is problematic to maintain stablelight color conditions. Even inexperiencedviewers can see color differences and het-erogeneous light color conditions at colorpoint tolerance levels of ∆E= 2.5 to 3.

Example: A specific characteristic of thehuman eye is to react to color differences -whereas the evaluation of the absolute colorvalue is problematic without comparisonvalues. These differences in color percep-tion can even be increased by varying thebrightness levels. Therefore slight color vari-ances in LED panels or backlighting solutionscan result into a major technological issue.

Image 1: Dependence of wavelengthand brightness regarding to thetemperature of an RGB-LED


AGING EFFECTS

Even though the lifecycle of LED data sheetsdocument beneficial statistics compared tothe traditional light bulb - LEDs also experi-ence brightness drifts from the first day ofusage. Usually the lifecycle of an LED isbased on a brightness loss of more than 70%compared to the original values.Far before the 70% loss-level, differencesand heterogeneous lighting effects can beexperienced, which are proven by scientifictests in lighting laboratories.

Image 3 demonstrates the brightness char-acteristics of a RGB high brightness LEDwithin the first 5000 hours of operation. Aninteresting fact is that not only brightnessloss could be experienced, but also a tem-porary increase of the light output has beenrecorded. These characteristics differ, depending onthe used materials within red, green andblue LEDs. It has been proven that thebrightness loss within the first 5000 operat-ing hours can vary between 5% to 15%.

In other words - drift effects that can be seenby the average human eye. Achieving long-

term color point stability is also a require-ment to meet EnergyStar regulations.

Exchanging single LEDs within a lighting sys-tem, as a result to environmental effects ordamage can be a difficult and expensivemaintenance task. These maintenance andrunning costs can be drastically reduced viafeedback control options. The question is: “What kind of cost-effi-cient solution can resolve these issues?”

THE CONCEPT OF OPTICAL FEEDBACK SYSTEMSThere are known solutions to stabilize thecurrent and voltage of LEDs. There are alsosolutions that measure the temperature ofLEDS (as far as technological possible) andreport these values to the LED driver to cre-ate a temperature control-loop. These solu-tions are indirect regulation solutions. Analternative method is the direct regulationvia light color. This concept is shown inImage 4. The demonstrated solution differsfrom the (unregulated) control option byimplementing a color sensor, depending onthe lighting concept, to send RGB or othercolor values to the micro controller todirectly regulate the LED light output. Thesoftware of the micro controller comparesthe given and set values and directs these tothe output driver. Image 4 demonstrates an

RGB system. But this concept works for anyLED light source, such as RGB white or RGBamber-white.What is not demonstrated is how the colorsensor detects the light. Therefore it is use-ful to generate simple solutions whereasreflecting light can be send to the color sen-sor. In other words existing reflectors ofmanufacturers can be used to achieve thisgoal at no or hardly any cost increase.

BENEFITS OF OPTICAL FEEDBACKSOLUTIONSThe LED driver used in can be of simplisticand cost-efficient nature: even a driver with-out current or LED voltage regulation andwithout temperature sensor or feedback. A main issue of the overall savings is the cal-culation of the total costs as well as futuremaintenance costs. An additional issue is thequestion of LED binning. It would be ideal ifthe light sectors could be directly controlledvia the given light output. This would elimi-nate the requirement of buying from specif-ic bins or just from a single LED manufactur-er. Therefore this approach is not only tech-nological beneficial but can also save moneyduring the development planning. It isenough if a LED is within a specific color seg-

ment to later on adjust the overall light out-put. The consistency of the light will be reg-ulated via feedback control. If one wants to use the binning segmentshighlighted in green, the only requirement isto adjust regulation range. The regulationrange is usually set to a value of 30% basedon aging- and temperature drift effects,therefore the segment needed to eliminatebinning effects is of little importance. But itcan save money during the purchasingoperation, since tolerance ranges of LEDBinnings can be strongly reduced or eveneliminated. Often it is hard to buy the sameclasses/ranges of LEDs at one manufacturerwithout waiting periods. When taking theavailability of specific LED classes into con-sideration, this can ease the entire purchas-ing process and limit waiting times until thenext class of the same manufacturer is ready.The visual light color range is shown inImage 6. The continuous line demonstratesthe presentable color gamut based on alltolerances including the regulation range.

THE OVERALL SAVINGS POTENTIALIn the end of the calculation one needs torecognize the costs benefits and compare.Eliminating negative issues and effects of LEDs

such das binning or colorinconstancies as well as cre-ating a long-term stablesolutions are just some ele-ments, which can reduce theoverall development costsand future running mainte-nance costs. Therefore it isessential to find the rightsolution for the given prob-lem and weight the benefitsand costs. The given solution sets itselfapart from traditional light-ing systems by utilizing con-trol options of LED sources,

eliminating negative aging,temperature and light colorshifts, generating long-termstability and reducingpotential future mainte-nance costs. It is importantto choose a sensor that doesnot show aging-effects itselfand is based on the percep-tion of the human eye. The JENCOLOR sensors byMAZeT offer exact thesecharacteristics n

On an electrical toothbrush thecolor of the LEDs should be con-trolled. Furthermore the ON/OFF –times of the LEDs should be deter-mined, too. Thus a color sensor mustbe used, which is able to detectlightning sources and which comeswith a high scan rate and an ade-quate switching frequency. For the investigations a color sensortype SPECTRO-3-FIO-CL is used in

connection with an optical fiber typeR-S-A2.0-(2.5)-1200-67° and anoptical frontend type KL-M18-A2.0.The distance from the frontend tothe object is around 30 mm. Duringthe tests it has emerged that it ishelpful to use instead of the LEDOFF mode the DC mode, but withvery low power, just as much as nec-essary to see the white light spot.Since the white light spot shows

exactly the detecting area of thecolor sensor it´s easy to direct theoptical frontend KL-M18-A2.0 to theright position. As shown in thescreenshots, the white light spotinfluences the result of the LED lightjust a bit, which can be neglected. A proper detection of the color aswell as of the intensity of the respec-tive LEDs is possible. The results areshown in the screenshots.

Different colored interior components should be distinguished. For this purpose a color sensor type SPECTRO-3-50-FCL-JR is used. Thedistance from the color sensor to the object is approximately 50mm. The color sensor SPECTRO-3-50-FCL is using the direct light reflec-tion of the surface from the leather imita-tion, thus a combination of color andgloss control is realized. Especially onparts with no color difference, the differ-ent gloss values of different structuredobjects deliver a good possibility to dis-tinguish between the components.

As shown in the screenshots, a properdifferentiation of the leather imitations ispossible.

A matt chromate knob should be dif-ferentiated from a glossy chromateknob. Both types are used in the auto-motive interior field. For this purposeand after we have tested all of the dif-ferent color sensor types without anysuccess, we have decided to use a

laser displacement sensor type L-LAS-LT-50-CL, but not to measurethe distance to the object, but to usethe different reflectivity of the mattand the glossy surface. The distanceto the object is approximately 50mmand the peak of the video signal from

the matt surface, which can beobserved on the Windows® surface, issignificant higher than the peak fromthe glossy surface (which is nearlyzero). The screen shots show that aproper differentiation between mattand glossy knob is possible.

MSC Technologies, a business group of Avnet ElectronicsMarketing EMEA, a business region of Avnet Inc. (NYSE: AVT),delivers the first engineering samples of LCD modules made byKyocera based on an innovative on-cell technology. The new on-cell technology ensures an excellent optical performance andgood readability of the display coupled with small thickness andreduced weight.

For the on-cell technology, the projected capacitive (PCAP) touchsensor is attached directly to the glass front of the display. Thepolarizing filter is attached above it, without any air gap to thetouch screen. The touch-screen controller is also fully integrated inthe display module. Because the touch-screen panel and the con-troller are less subject to the electromagnetic radiation of the LCdisplay and the application environment, they operate with signif-icantly lower radiation effects than displays with separately glued-on touch screen. Furthermore, the simple integration of on-cellLCD modules is possible.The 7 inch (17.8 cm) TCG070WVLRxPCxGDx118/117 TFT mod-ules with USB/I²C interface are available as first samples. The resolu-tion is 800 × 480 pixels with aspect ratio 15 : 9. The contrast ratio isspecified as 650 : 1. The displays are based on wide-view technolo-gy with 85 degrees in all directions and achieve a brightness of 500cd/m². The 30-pin single channel LVDS data interface with 6-bit RGBsupports a color palette of maximum 262 K colors.The outline dimensions of the LCD module are 169.8 × 109.7 × 9.2mm. The active area is 152.4 × 91.44 mm. The display surface isequipped with an anti-glare film that has anti-fingerprint treat-ment. Thanks to its very good readability, the display is also suit-able for outdoor applications. The extended operating tempera-ture range is -30°C to +80°C.For applications that require the display to also be read in brightsunlight, the TCG070WVLR×PC×GD×140 model is offered withI²C interface and optically-bonded cover glass.MSC TECHNOLOGIES www.msc-technologies.eu

Harwin, the leading hi-rel connector and SMT board hardwaremanufacturer, now offers its EZ-Shield Can EMC protectionscreening products in kit form, enabling designers to rapidlyconstruct PCB cans at minimal cost for development purposes.Harwin’s EZ-Shield Cans are simply pressed onto pre-posi-tioned surface mount EZ-Shield Clips forming an EMC cagearound sensitive ICs and electronic circuitry. This saves expen-sive, labour-intensive secondary assembly and facilitatesrework. A range of can sizes and clips are available. However,during development and test, typically engineers have had toorder bespoke cans without being 100% certain of their even-tual requirements, incurring costs and creating delays.Now, a can may be created easily and effectively in minutes,with no special tools or experience required.

The low cost kit comprises two 80mm × 60mm × 0.3mm thickNickel Silver sheets that are pre-scribed on a 5mm grid toallowing easy cutting and forming, enabling the user to pro-duce a shield can of the required dimensions. Auto-placeableEZ-Shield Can Clips which hold the cans securely in place arealso included.

Comments Product Manager, Paul Gillam: “Product testing hasconfirmed that the nickel silver material used provides effectiveand useable shielding, with up to 24dB attenuation achieved,depending on frequency and configuration. We believe that thekits will save costs and time during development, and help toenable that an optimised EMC solution is found.”

The EZ-Shield Kits complement Harwin’s of standard clips andcans which offer a highly cost effective method of screening.Auto placement of the related clips allows post assembly sol-dering and de-soldering operations to be eliminated leadingto significant reduction in PCB damage. Applications will befound in many markets, ranging from Consumer Electronicsthrough to the Industrial, Instrumentation and Control Systemsenvironment.

Toshiba Electronics Europe has expanded its range of pho-torelays with the addition of four ultra-small devices. TLP3475and TLP3440 have been designed to deal with high frequen-cy signals, while TLP3417 and TLP3420 are designed to dealwith the high voltages required for signals of measureddevices such as semiconductor testers. The devices have beendesigned for applications where the mounting areas onboards need to be drastically reduced and high speed / highvoltage signals need to be measured – for instance in applica-tions such as semiconductor testers, measurement equipment,medical devices and probe cards. They consist of a photoMOSFET optically coupled with an infrared light emittingdiode squeezed into an ultra-small VSON4 package.Photorelays provide design engineers with fast switchingspeed, high reliability, lower power consumption, and noise-free operation, making them an alternative to mechanical

relays. As the cabinets of various types of semiconductortesters and measurement equipment are becoming smaller,the need for ultra-small photorelays has increased. TheVSON4 package enables high-density assembly and byreplacing USOP4 packages, can shrink the assembly area by50% and the assembly volume by 60%. TLP3475 has ON-state resistance of 1Ω (typ.) and outputcapacitance of 12pF to improve pass characteristics at thetime of relay contact-on and avoid problems during high fre-quency signal transmission. The chip-on-chip device also fea-tures OFF-state terminal voltage of 50V (max.) and ON-statecurrent of 0.3A (max.) TLP3440 features improved leakagecharacteristics for high frequency signals in the off state withOFF-state output terminal voltage of 40V (max.), ON-statecurrent of 0.12A (max.), ON-state resistance of 12Ω (typ.)and output capacitance of 0.45pF. Electrical characteristics of the new devices are equivalent tothose of existing TLP3375/3340 photorelays in USOP4packages, while the mounting area has been reduced byabout 50%.TOSHIBA ELECTRONICS EUROPE www.toshiba-components.com
