CheckoutourfreeMiWi™protocolstackforIEEE802.15.4wirelessnetworkingincost-sensitiveapplicationswithlimitedmemorytoo!

Microchip has added three offerings for IEEE 802.15.4 wireless networking. Microchip’s first RF transceiver, the MRF24J40, is a 2.4 GHz IEEE 802.15.4 transceiver targeted for the ZigBee™ protocol and proprietary wireless protocols in RF applications requiring low power and excellent RF performance. The ZENA™wirelessnetworkanalyzer tool further enables development of ZigBee protocol systems using Microchip’s semiconductors. Finally, the MiWi™ protocol is a free, small-footprint protocol developed by Microchip for customers who do not need ZigBee protocol interoperability but want to use IEEE 802.15.4 transceivers in low-cost peer-to-peer, star and mesh networks. In fact, the MiWi protocol provides the lowest-cost fully functional network protocol for IEEE 802.15.4 transceivers.

According to In-Stat, the market for IEEE 802.15.4 wireless personal area networking, via the ZigBee specification network layer and other proprietary protocols, could grow 200% by 2009 – with annual shipments surpassing 150 million units in 2009. Microchip is currently addressing the needs of this market with the only zero-cost-license and royalty-free ZigBee protocol stack, which is one of the smallest in the industry and provides a source-code format that allows you to customize your product, utilizing our broad portfolio of compatible PIC® microcontrollers.

With the MRF24J40 transceiver, Microchip now offers a complete ZigBee protocol platform through the addition of a highly integrated RF transceiver that requires very few external components. Microchip’s radio also offers low power consumption and performance that exceeds all IEEE 802.15.4 specifications, with full Media Access Controller (MAC) support and an Advanced Encryption Standard (AES) hardware encryption engine.

AlternativeProtocolsDue to the fact that the ZigBee protocol has grown too large and complex for many applications, a large percentage of the market for IEEE 802.15.4 wireless Personal Area Networking is likely to use alternative, proprietary protocols, such as the MiWi protocol. Additionally, ZigBee protocol certification is costly and cumbersome for small- and medium-size companies. Microchip’s MiWi protocol provides a simpler, lower-cost solution for customers who do not need interoperability but still want to use robust IEEE 802.15.4 radios. No certification is required for MiWi protocol systems,

and the protocol stack is provided under a free license, when the combination of Microchip’s microcontrollers and MRF24J40 transceiver is used.

Regardless of which protocol you select, Microchip’s complete solution enables you to rapidly evaluate and begin developing a vast array of wirelessly networked IEEE 802.15.4 applications, including: building/home automation (security, lighting, HVAC, access); industrial (monitors, sensors, automation, control, lighting); personal healthcare (diagnostic tools, monitors); and consumer electronics (RF wireless remotes for TV/VCR/DVD/CD, toys, personal-computer peripherals).

Microchip’s new ZENA wireless network analyzer tool (part # DM183023), available now for $129.99, uses a simple graphical interface to configure the free Microchip ZigBee and MiWi protocol stacks. This enables customers to reduce the code size of the stacks by removing optional features; cuts development time by simplifying the interactions with the stacks; and allows customization of the stack to fit a particular need. Consisting of both hardware and software, the ZENA wireless network analyzer is an IEEE 802.15.4 protocol analyzer that is capable of decoding ZigBee and MiWi protocol packets – from the lowest layers to the top of the stack (including the security modules). The network-configuration display window allows users to see the traffic in real time, as it travels from one node to another. A session can also be saved to a file, to allow further analysis of all the network traffic.

This augments Microchip’s existing IEEE 802.15.4 development tools, including the $269.99 PICDEM™ Z 2.4 GHz Demonstration Kit (part # DM163027-4), which is an easy-to-use evaluation and development platform for IEEE 802.15.4 application designers. The kit includes all of the hardware, software source code and printed circuit board (PCB) layout files needed to rapidly prototype wireless products. Additionally, an instructional application note is available on Microchip’s web site at www.microchip.com/zigbee. This development platform is based on Microchip’s PIC18 high-performance microcontroller family, which supports IEEE 802.15.4 applications and offers a wide selection of products with 32 Kbytes to 128 Kbytes of Flash program memory in 28- to 100-pin packages.

Microchip’s MRF24J40 IEEE 802.15.4 transceiver is available now for samples through Microchip’s local sales offices, and production is planned for December. In 10,000-unit quantities, the MRF24J40 starts at $2.99 each in Pb-free/RoHS-compliant, 40-pin, 6x6 mm QFN packages.

The 14-pin PIC16F616/610 and the 8-pin PIC12F615/609 microcontrollers can substantially reduce your system component counts and costs through the integration of specialized peripherals, such as a full-bridge Pulse-Width Modulator (PWM) with dead-band control, a Timer1 Gate for pulse width measurement, a comparator for Hall-effect sensor interfaces, and an A/D converter for temperature and various monitoring functions. In the case of the PIC16HV616/610 and PIC12HV615/609 variants, the addition of an internal shunt regulator allows the PIC microcontroller to run from higher voltage rails without the

addition of voltage regulators.

Are you designing small-motor control systems and looking for ways to eliminate components and reduce board size and cost, while achieving higher levels of functionality and flexibility? For example, in cooling fans, the PIC16F616/610 and PIC12F615/609 Flash microcontrollers provide greater functionality than discrete fan-control components, such as linear speed control, improved dynamic response and the ability to customize the design with firmware changes rather than expensive hardware redesigns. At the same time, board space and cost is reduced with features such as comparator hysterisis, to allow direct interfacing to a Hall-effect element without additional signal-conditioning circuitry.

Many high-voltage-rail applications, such as motor control and power supplies, require components to step down the input voltage for various control devices. However, these new PIC microcontrollers – available with an integrated shunt regulator option (designated with “HV” in the part number), allow you to design systems without having to add a regulator, reducing costs and board space even further. Additionally, motor and power applications often require intermediate voltages for power drivers and other power components. The PIC16F616/HV616 family addresses these requirements with a built-in S/R latch to design a switch-mode power supply for

these intermediate voltages.

Specific application examples include: home appliances (such as blenders, toasters, smoke alarms and thermostat controls), cooling-fan control and other motor control, power tools, system control and monitoring, battery chargers, automated door sensors, speedometers and power supplies.

Key features for the PIC16F616/610 and PIC12F615/609 microcontrollers, and their HV variants, include:

• Enhanced full-bridge PWM peripheral with capture and compare functionality, dead-band control and emergency shutdown

• Internal shunt regulator that allows high-voltage VDD support from 2V to a user-defined max (HV variants, only)

• Up to two comparators with selectable hysteresis, internal voltage-reference options, and S/R latch mode for switch mode power conversion

• Up to eight 10-bit analog-to-digital conversion channels

• High stability, precision 4/8 MHz internal oscillator

• Up to 3.5 Kbytes (2K Words) of Flash program memory; 128 bytes RAM

• Brownout Reset (BOR) and Watchdog Timer (WDT) for reliable low-power operation

These new microcontrollers are supported by the full suite of Microchip’s development tools, including the free MPLAB® IDE Integrated Development Environment, the low-cost MPLABICD2In-CircuitDebugger and theMPLABPM�UniversalDeviceProgrammer.

The PICkit™2StarterKit (DV164120), now on sale at www.microchipdirect.com, enables engineers, students and anyone with an interest to easily begin development and experimentation with the PIC16F616/HV616 family for a very low initial investment of $49.99. The kit connects to any personal computer via full-speed USB 2.0, which allows faster programming and firmware upgradeability, and requires no additional

power supply for the programmer or target application board.

The PIC16F616/610 and PIC16HV616/610 microcontrollers are available now for general sampling and volume production in Pb-free, RoHS-compliant 14-pin PDIP, SOIC, TSSOP and QFN packages. The PIC12F615/609 and PIC12HV615/609 are also available now for general sampling and volume production in Pb-

In model aircraft parlance, kit bashing is defined as the practice of using the materials from a kit for one aircraft to build a similar, but different, aircraft. So, bit bashing is the process of using the features of one or more simple peripherals to build a more complex custom peripheral.

This month’s Bit Bash:

Scalethesignalup, Scalethesignaldown, Ireallyneedadigi-pot OrmaybeaworkaroundWritten by: Keith Curtis, Principal Applications Engineer

Often when controlling a linear signal, it is desirable to be able to scale an analog signal’s amplitude, under digital control. A good example of this is a PFC circuit; it scales the AC voltage waveform to generate a reference signal for the initial boost section of the converter. This keeps the load to the AC line proportional to the voltage, and the converter looks resistive. Unfortunately, the converter also needs to scale the reference value based on the intermediate voltage at the output of the converter, so a PFC needs a method for scaling the AC signal it uses as the reference.

Bit Bashing; The practice of combining peripherals, external components and firmware to create a new function, feature or peripheral (slang)

Continued on next page...

A digital potentiometer (digi-pot) is the simplest method to accomplish analog scaling of a signal; however, for low frequency analog systems, an alternative method, using an on chip , digital peripherals (CCP), can be used. This method uses a low pass RC filter, a MOSFET transistor and the CCP as a digital PWM. See Figure 1.

The corner frequency of the low pass filter is chosen to be approximately 50x to 100x the maximum frequency of the analog signal, such that the filter’s response characteristics will not adversely affect the amplitude or phase of the signal. The PWM frequency must also be 100x to 200x the corner frequency of the RC filter, so the PWM frequency will not pass an appreciable amount of energy through the filter. The result is a “shorting out” of the incoming signal, by the PWM signal (using the transistor), such that only a percentage of the original analog signal passes through to the output of the filter. The percentage of the incoming signal that is passed through the filter is determined by the duty cycle of the PWM. The RC filter then strips the PWM frequency off the chopped analog signal, smoothing out the signal to its original shape.

The result is a simple method for scaling any analog signal, using a few passive components, a transistor and a common digital PWM peripheral.

Now, as you might expect, there are some limitations that must be kept in mind when using this scaling system:

1. The maximum frequency harmonic of the analog signal must be less than the corner frequency of the RC filter to prevent distortion of the signal.

2. The higher the PWM frequency, relative to the RC filter’s corner frequency, the more the filter will attenuate the PWM frequency.

3. Note, because the resistor in the filter is split, the actual corner frequency seen by the PWM signal is actually 2X the frequency seen by the analog signal.

4. This puts the PWM frequency quite high, and the analog signals frequency quite low, limiting the useful frequency range of the technique.

5. If a BJT transistor is substituted in place of the MOSFET, then the maximum attenuation possible will be limited by the saturation voltage of the BJT transistor. And, there will also be non-linear distortion of the analog signal at high attenuation setting.Figure 1 Analog Signal Attentator

RETURNTOFRONTPAGE

Continued from previous page...

Fortunately, there are also a couple of tricks that can be employed to help out;

1. The RC filter can be replaced with a single, or multiple, pole LC filter to increase the attenuation of the PWM frequency.

2. The resistors used in the RC filter can be divided unevenly, such that R1 is much smaller than R2, this lowers the frequency of the filter corner frequency relative to the PWM signal.

3. The range of attenuation possible can be increased by adding a resistive divider, either before or after the system, with the ground connection of the shunt resistor controlled by an I/O pin. See Figure 2.

4. The resolution of the PWM can be increased by using a “dithering technique” presented in Microchip’s AN1050.

So, using a relatively common digital peripheral, it is possible to scale an analog signal under digital control, and the only external components are a transistor, and a couple of resistors and capacitors.

Microchip delivered its five-billionth microcontroller, the PIC18LF8720-I/PT, barely a year after delivering its four-billionth in September 2005. Today, Microchip produces more than 400 different PIC Microcontrollers (MCUs). The five billionth PIC MCU shipped, the PIC18LF8720-I/PT, highlights the unique 8-bit PIC18 architecture, providing 128 Kbytes of high-endurance Flash program memory. Most 8-bit MCUs only support program memory up to 64 Kbytes or less, forcing you to change platforms when your program size grows. The PIC microcontroller 8-bit architecture scales up to 2 Mbytes, maintaining software investments and allowing you to reuse your software across a wide range of MCU products.

“Shipping our five-billionth PIC microcontroller is a remarkable achievement, and shipping it to a customer in China is even more satisfying as this year we celebrate the 10th anniversary of the opening of our first China office in Shanghai in 1996,” said Microchip’s president and chief executive officer Steve Sanghi. “In the 10 years we have been in China, we have enjoyed rapid growth, which we expect to continue. We have opened 11 offices and are continuing to make other investments in the community, such as setting up comprehensive training and university programs that are grooming the engineers of the future.”

According to Sanghi, “We have reached this milestone because our PIC microcontroller architecture, MPLAB® development systems, and direct sales and sales-channel partners provide maximum benefits for customers to reach their design goals.”

A Microchip customer for five years, Linyang is one of the largest manufacturers of power meters in China – with over 1,600 employees spread across 22 locations and an annual sales revenue of RMB 800 million 2004.

Linyang, today, uses a broad line of embedded-control solutions from Microchip, including PIC microcontrollers and dsPIC® digital signal controllers, serial EEPROMs and analog devices. “Our long-standing relationship with Microchip Technology has been beneficial to both parties, and we are proud to be the recipient of their five billionth PIC microcontroller,” said Yonghua Lu, president of the Linyang Group. “The exceptional development tools and support from Microchip helped speed our product development and qualification time.”

If you are looking for an easy way to stay up to date with Power Mangement training, take a look at Microchip’s on-demand web seminars at www.microchip.com/webseminars. There are 11 different web seminars available for viewing online or downloading from battery charger topics to switch mode power supplies. Adding to this library of material this month is Power Management modes on the dsPIC33F and PIC24 Products.

Mike CatherwoodDSC Core Architecture Manager

Power Management modes on the dsPIC33F and PIC24F/H Products

Many microcontrollers provide some degree of power management capability, but it is a generic term, and if the power management features are not sufficiently broad and flexible, users may not be able to attain power budget goals. To that end, the 16-bit PIC33F and PIC24 families offer a wide range of power reducing

options that may be ‘mixed and matched’ as desired. This provides the user unprecedented flexibility in controlling power consumption, while maintaining a simple to understand structure, and easy-to-use power mode entry and exit options.

In this web seminar, Mike Catherwood examines the various Power Management options that are possible when using the dsPIC33F and PIC24F/H families of 16-bit microcontrollers. Topics include the application of the power saving instructions, discussion of clock control options, and the use of the DMA controller to reduce power consumption. The power saving instructions, Sleep and Idle, and the power-saving Doze mode are discussed at length, with special attention being given to entry/exit, and the application of these features with any exception or the watchdog timer.
