1.3 Important Notes

Safety Instructions

Caution To avoid personal injuries and damage to property you have to read and understand the following safety instructions and hazard warnings prior to installation and use of this ECU. Keep this documentation always near the ECU.

Proper Use and Intended Purpose

Caution The ECU is designed to provide a development platform for testing and evaluating automotive specific software.

The ECU may only be operated (i) according to the instructions and descriptions of this manual; (ii) with an electric power supply as defined in this manual; and (iii) with accessories manufactured or approved by Vector.

The ECU is exclusively designed for use by professionals solely at research and development facilities for research and development purposes.

The ECU may only be operated according to the instructions and descriptions of this manual. The ECU is exclusively designed for use by skilled personnel as its operation may result in serious personal injuries and damage to property. Therefore only those persons may operate the ECU who have understood the possible effects of the actions which may be caused by the ECU. Users have to be specifically trained in the handling (e.g. calibration) with the ECU, the applied embedded software and the system intended to be influenced. Users must have sufficient experience in using the ECU safely.



Hazard Warnings

Caution

The electronic control unit and its connected loads may get very hot due to high power dissipation under full load.

The ECU may control and/or otherwise influence the behavior of control systems and electronic control units. Serious hazards for life, body and property may arise, in particular without limitation, by interventions in safety relevant systems (e.g. by deactivation or otherwise manipulating the engine management, steering, airbag and/or braking system) and/or if the ECU is operated in public areas (public traffic). Therefore you must always ensure that the ECU is used in a safe manner. This includes inter alia the ability to put the system in which the ECU is used into a safe state at any time (e.g. by “emergency shutdown”), in particular without limitation in the event of errors or hazards. Furthermore all technical safety and public law directives which are relevant for the system in which the ECU is used must apply. Provided that serious hazards for life, body and property may occur and before the use in public areas the system in which the ECU is used must be tested according to recognized rules of engineering in a non-public area.

Disclaimer

Caution Claims based on defects and liability claims against Vector are excluded to the extent damages or errors are caused by improper use of the interface or use not according to its intended purpose. The same applies to damages or error arising from insufficient training or lack of experience of personnel using this electronic control unit.

Description The core of the VC36B-12 consists of the microcontroller, the Ethernet switch and the system basis chip (SBC).

The microcontroller handles all discrete input, output, LIN and CAN channels. Each channel is connected either discrete or over a SPI interface. Further information on the structure and connection of the channels is given in the following chapters.

The Ethernet switch is connected to the microcontroller via SPI and an optional MDC/MDIO connection. The Ethernet switch manages the BroadR-Reach and the



100Base-TX channels. They can be configured via SPI or MDC/MDIO interface. The channels can also be used by the microcontroller of the VC36B-12.

The system basis chip ensures correct operation of the main controller using a window watchdog and voltage observation. It also handles power management and wakeup events. One CAN and one LIN transceiver are integrated in the system basis chip. The communication with the microcontroller is realized with an SPI interface.

Additionally, the VC36B-12 provides further features as described below.

Four digital inputs – two for high-side switches, two for low-side switches – provide the capability to capture switch inputs.

An unbuffered RTC provides the ability to supply the system with time and date.

Further communication channels are provided in form of 3 CAN FD and PN capable CAN-channels.

The four Outputs (HS-Out 1A) are not intended to be used in the current HW version. The Pins must not be contacted to any other devices, supply voltages or shortened to ground. The information about the output is informative.

2.2 Supply

2.2.1 Supply Concept

Description The VC36B-12 contains one terminal 30 to supply power to the ECU. The scheme below shows the supply concept.

The system basis chip works as main power management unit and supplies the microcontroller as well as the switch via its DC/DC-converter with 3.3 V. The microcontroller as well as the switch generates its core supply voltage of 1.3 V, respectively 1.0 V, with its own DC/DC regulator. A linear regulator generates the 1.8 V supply voltage for the switch.

The communication channels are supplied by the SBC’s external linear regulator. The digital inputs are supplied by a switchable voltage and the high-side outputs are supplied by a protected voltage. A standby regulator ensures the operation of the RTC during sleep and the wakeup functionality of the switch.

Protection The VC36B-12 is protected against reverse battery connection and transients on the supply lines.

2.2.2 Power Management

Overview Power management of the VC36B-12 is primarily performed by the system basis chip and the microcontroller.

In sleep state the microcontroller is not supplied. Therefore, observation of all wakeup sources is done by the system basis chip. If a wakeup reason occurs, the system basis chip saves the information of the wakeup event and activates the microcontroller.

In normal operation the microcontroller monitors the reasons for staying awake and switches to sleep mode if no more reasons are present. The supply of the peripheral units is controlled by the microcontroller. It is activated during startup of the microcontroller.

2.3 Core

2.3.1 Microcontroller

Description The SAK-TC297TA of Infineon is a 32-bit high performance controller with three cores and a maximum frequency of 300 MHz. The controller has a code flash memory of 8 MB and a RAM of 728 kB + 2 MB for RADAR/Camera Image Storage. It handles all input, output, LIN and CAN channels. The peripherals are connected via SPI, GPIO pins or peripheral dependent hardware modules of the controller.

Programming interface

The microcontroller can be flashed and debugged through a device access port (DAP) interface. A ten pin SMT micro header is soldered on the PCB of the VC36B-12 to connect this interface without the need of a needle bed adapter or other special equipment. The pin allocation of the connector corresponds to most standard debug and flash tools on the market and is shown in the table below.

Reset generation In normal operation the reset signal is pulled to the supply voltage of the microcontroller through a resistor. If the window watchdog is not triggered correctly or if the supply voltage of the microcontroller is out of the nominal range, the SBC pulls the reset signal active low.

Further information For further information about the microcontroller refer to the TC29x data sheets from Infineon.

2.3.2 System Basis Chip

Overview The VC36B-12 contains a MC33908LAE system basis chip from NXP. The chip includes functions for observation, power management, the transceivers for LIN0 and CAN0 and several voltage regulators.

Voltage regulator and power management

The SBC regulates and observes the supply voltage of the microcontroller. The supply voltage is activated by a wakeup event through the power management and is switched off in sleep mode of the VC36B-12. Entering sleep mode is controlled by the microcontroller software.

In fault conditions the SBC tries to restart the microcontroller through reset generation. If the fault condition is not solved, the supply of the microcontroller is switched off. For debugging reasons this behavior can be disabled.

Watchdog and reset control

A windowed watchdog with “challenge / response” principle is included in the SBC to observe the correct operation of the microcontroller. If the watchdog is not triggered within the defined time window, a reset signal is generated, except working in debug mode.

Debug mode Working in debug mode, the window watchdog of the SBC doesn’t have to be triggered to prevent reset generation and supply voltage shut off. This mode can be used for flashing and debugging the VC36B-12.



The SBC enters debug mode after power up, if the pin header with two pins on the PCB is connected. Entering debug mode without plugged header or without power up is not possible. To exit the debug mode, the header must be unplugged and a T30 reset has to be performed.

CAN and LIN transceiver

The transceiver for CAN0 and LIN0 are integrated in the SBC. The transceivers can be configured by the microcontroller through SPI commands.

Further information For further information about the SBC refer to the MC33908LAE data sheets from NXP.

2.3.3 Switch

Description The VC36B-12 contains a Broadcom BCM89531 BroadR-Reach switch. The switch is configured to have five BroadR-Reach channels. Two ports are configured as MII ports to communicate with the microcontroller and the 100Base-TX transceiver.

100Base-Tx interface The 100Base-TX transceiver is connected to the switch with a standard MII and additionally with a MDC/MDIO interface. Details can be found in section Ethernet on page 18.

EEPROM If shorter startup times are required, the Ethernet switch can also be configured by using an external NOR-Flash with 128 Mbit. The Flash is connected via QSPI to the switch.

Note The flash is not populated in standard configuration.

Example of use The Switch can be used as central BroadR-Reach gateway

2.4 Communication

2.4.1 LIN

Description The VC36B-12 contains one LIN transceiver, which is compatible to the LIN protocol specification 1.3, 2.0, 2.1, 2.2 and SAEJ2602-2. The channel is configured as LIN master.

Wakeup The wakeup ability of the system basis chip is configurable. The ECU cannot enter sleep mode while there is any communication. For further information about wakeup and power management see chapter 2.2.2.

2.4.2 CAN

Description The VC36B-12 contains four high speed CAN channels. The CAN0 transceiver is integrated in the SBC and fulfills the ISO 11898-2 and -5 standards. The channels CAN1, CAN2 and CAN3 are CAN transceiver, which support Non-ISO CAN FD and partial networking. These three channels are compliant with the ISO 11898-2:2003, ISO 11898-5:2007 and ISO 11898-6:2013 standards.

Wakeup Communication on the CAN channels will lead to a wakeup of the VC36B-12. The ECU cannot enter sleep mode while there is communication on any of these channels. For further information about wakeup and power management see section

Power Management.

Structure CAN1…3 All CAN channels except CAN0 use individual transceivers. The partial networking channels are realized with a TJA1145T transceiver from NXP and each of them is configured via an own SPI. If the partial networking function is not needed, the transceiver can be replaced by the TJA1043T transceiver in series applications.

The VC36B-12’s PCB provides pads for bus termination, which are not populated in standard configuration. If a termination is needed, two resistors (61.9 Ω, 1 %) and one capacitor (4.7 nF, 50 V, 10 %) have to be populated for each channel.

2.4.3 BroadR-Reach

Description There are five BroadR-Reach channels available in the VC36B-12 which can be used for communication over an unshielded single twisted pair connection.

Structure All needed filter components for interference-free operation are integrated in the switch except the common mode chokes. The diodes and capacitors which are connected to GND protect the lines against transients and ESD impulses. The series capacitors block DC voltages which are present in power-over-Ethernet (PoE) systems.

2.4.4 Ethernet

Description There is one 100Base-TX transceiver in the VC36B-12. This interface can be used for communication with up to 100 Mbit/s over two twisted pair cables.

Wakeup The 100Base-TX interface cannot wakeup the VC36B-12. A sleeping VC36B-12 will remain in sleep, even if there is communication on this channel. For this reason, the ECU is able to enter sleep mode independently of communication on the 100Base-TX interface.

Structure The interface uses the Ethernet physical layer transceiver DP83848Q-Q1 from Texas Instruments. It is connected to the switch via MII. The transceiver can be configured via its MDC/MDIO-interface which is also connected to the switch. The two signal lines are terminated with a split termination of two 49.9 Ω resistors and a 0.1 µF capacitor. The electronic control unit is electrically isolated from the external signal lines by transformers. The interface is protected against electrostatic discharge by quadruple rail-to-rail ESD protection.

2.5 Inputs

Description The VC36B-12 contains four digital input pins DIN0…3. Two inputs support switches to ground, the other two inputs support switches to battery level. All four channels have wakeup functionality with unique identification possibility by the SBC. An error detection function is implemented on each channel.

Example of use > Connection of switches to GND

> Connection of switches to battery level

> Connection of T15 signal for wakeup

Diagnostics Error detection on the digital input channels is limited due to the fact that a short circuit is electrically identical to a closed switch and that an open wire is essentially the same as an open switch. Errors can only be detected using switchable current sources and logical interpretation of implausible conditions in software. Implausible conditions are a short circuit to GND for high active inputs (DIN0, DIN1) and a short circuit to supply voltage for low active inputs (DIN2, DIN3).

Structure of DIN0 / DIN1

The high active digital inputs contain ESD protection, a switchable resistor for the diagnostics function, a comparator with fixed threshold, a low-pass filter with a cutoff frequency of 159 kHz and a wakeup line. The output of the comparator is directly connected to a GPIO of the microcontroller. A hysteresis is implemented to reduce switch bounce.

DIN2, DIN3 (low active) 2.1 V

2.6 Real Time Clock

Description The VC36B-12 includes a Real-Time Clock (RTC) and calendar with the possibility to generate a wakeup signal on its interrupt line. The RTC provides values for year, month, day, weekday, hours, minutes and seconds based on a 32.768 kHz quartz crystal.

The unbuffered real time clock is supplied by a standby regulator to ensure the possibility of time triggered events during sleep. It is connected to the microcontroller via SPI. The interrupt line of the real time clock is connected to the system basis chip to generate a wakeup.

If the real time clock generates a wakeup, the signal is active until it gets cleared by a SPI command.



Note The RTC is not temperature compensated. The RTC values may drift due to temperature changes.

5 Appendix A: Release Notes

Release Notes Subject Description

Testing level / sample grade The VC36B-12 is a prototype / A-sample for evaluation purposes only. Therefore, it is not fully tested.

Ethernet wakeup detection on port basis / Switch wakeup

Due to hardware limitation the detection of wakeup events of the switch is not possible.

EMC The hardware does not fulfill the OEM harmonized EMC standards yet.

Quiescent current The quiescent current can be higher than specified depending on the actors / sensors connected to the inputs.

T30 measurement slightly too high / T30 measurement incorrect after sleep

The internal reference voltage and therefore all voltage measurements are incorrect after a wakeup via CAN0. This may not be present on all devices.

Temperature range of BroadR-Reach and Ethernet

The BroadR-Reach and Ethernet communication will not operate beyond the specified temperature range. Additionally, at high temperatures the SPI communication to the RTC is disturbed.

High-Side Output diagnostics Diagnostics of the outputs operates beyond specification under a voltage of 8 V and may provide incorrect results.

High-Side Output voltage measurement The internal reference voltage and therefore all voltage measurements are incorrect after a wakeup via CAN0. This may not be present on all devices.

High-Side Output Short-To-Ground The hardware may be damaged by a short to ground fault.

100Base-TX link establishment The link up-times on the channel 100Base-TX may take an unexpected long time.

Inductive loads Inductive loads are not supported.
