NCV73810V2GEVB NCV7381 FlexRay) Bus Driver Evaluation Board User's Manual http://onsemi.com EVAL BOARD USER’S MANUAL Introduction allows users immediately start with the NCV7381 FlexRay Bus Driver. The MCU is preprogrammed with a firmware which provides simple mode control and FlexRay communication. With use of Freescale BDM programmer and a suitable development environment, the MCU firmware can be freely modified and reprogrammed. This document describes the NCV7381 APP V2 Evaluation board for the ON Semiconductor NCV7381 FlexRay® Bus Driver. The functionality and major parameters can be evaluated with the NCV7381_APP_v2 board. The NCV7381 is a single-channel FlexRay® bus driver compliant with the FlexRay® Electrical Physical Layer Specification Rev. 3.0.1, capable of communicating at speeds of up to 10 Mb/s. It provides differential transmit and receive capability between a wired FlexRay® communication medium on one side and a protocol controller and a host on the other side. NCV7381 mode control functionality is optimized for nodes permanently connected to car battery. Additional details can be found in the NCV7381 datasheet.

The board is prepared for various modifications in power supply concept and FlexRay bus termination, and allows simple extension of the system by unused MCU pins. USB interface provides compatibility with standard PC. The address of each board can be easily modified by address switch what allows creating complex FlexRay network without need of reprogramming the MCU. Implemented High Speed CAN interface can be used as a diagnostic interface in a network built from several nodes. For evaluation purposes NCV7381 is populated with several LED diodes and most of the bus driver signals are comfortable accessible to oscilloscope probes. The NCV7381_APP_V2 Evaluation board is a reference design for stand-alone 2-channel FlexRay® node. The board is intended to give designers easy, quick and convenient means for evaluation of NCV7381 FlexRay bus drivers. The design incorporates complete node solution with possibility of modifications and small board size.

Only a few steps need be proceeded to get fully working simple FlexRay network. Connect the evaluation boards as follows: 1. Set the boards to default configuration according to Jumpers and Default Configuration section 2. Set a different board address on each board. One of the boards must be set with address 1 and is considered as Master Board. Node address is configurable by address switch (SW12) – see Address Switch section for details 3. Connect the boards according to figure below 4. Optionally connect an oscilloscope to any test-point as needed 5. After the power supply is applied, FlexRay communication is automatically initialized With properly running setup, button SW11 (#IRQ) has following functions: • Press the button shortly to read-out Bus Driver status register (Only in Bus Driver status indication mode) • Press and hold the button for approximately 2 seconds to change LED bar indication mode. Three modes are available: ♦ ♦ ♦ ♦ FlexRay communication indication – each LED is assigned to one slot according to LED number. The LED is blinking if the respective slot in FlexRay communication is active Bus Driver status indication – Channel A, Bus Driver status indication – Channel B: LED1 – Local Wake-Up status LED2 – Remote Wake-Up status LED3 – TxEN-BGE Timeout status LED4 – Bus Error status LED5 – Vio Undervoltage status LED6 – Vcc Undervoltage status LED7 – Vbat Undervoltage status LED8 – Power On status Press and hold the button for more than 5 seconds – Both nodes are switched to SLEEP mode and can be woken-up by one of the Local Wake-up switches.

Each board is programmed with the same firmware, so every node in the network must be configured with different unique number. Be careful: LSB is situated on the left. ON means the particular switch is closed and output is Logical 0! OFF means the particular switch is open and output is Logical 1! 0 1 2 3 4 5 6 7 SW12 OFF ON MCU Reset Button This switch is used for generating low level at the MCU Reset pin. If MCU detects low level at the RESET pin external reset is performed. MCU External Interrupt Button The MCU interrupt module support one maskable interrupt input. This input is connected to SW11. BD Local Wakeup Buttons The FlexRay Bus drivers support Local Wakeup event detection. If a falling edge is recognized on WAKE pin, a local wakeup is detected. These switches (each for one FlexRay channel) are used for simulation of Local wakeup event normally generated by e.g. mechanical switch. LEDs Three power LEDs indicate proper function of voltage regulators. In case the MCU and the NCV7381 bus drivers IO cells use the same power supply (as by default) MCU VCC LED and BD VIO LED signalling is also the same. The board contains a bank of eight general purpose LEDs (Green). Their function depends on the MCU program. There is also USB indication LED which is used to signal ongoing USB data transmission.

SPECIFICATIONS Power Supply The Evaluation board can be power either via DC power supply input socket with plug diameter 2.1 mm and length 14 mm or by one of the FlexRay bus connectors (See the connector description section). Maximum input voltage (42 V) is limited by on-board voltage regulators input voltage range. Split Termination In order to achieve a better EMC performance, it is recommended to make use of a so-called split termination in all ECUs, where the Termination resistance RT is split into two equal parts RTA and RTB [2]. ECU BP RTA BD C1 R1 RTB BM Figure 6. ECU with Split Termination [2] The serial RC combination (R1; C1) at the centre tap of the split termination provides a termination to GND for common mode signals. R1 is preferably omitted. Typical values are given in the following table: Table 5. TERMINATION PARAMETERS Name Description Typ Units R1 Resistor < 10 C1 Capacitor 4700 pF ≤2 % 2 x ⎪RTA − RTB⎪ / (RTA + RTB) Matching of Termination Resistors For RTA and RTB the use of 1% tolerated resistors leads to a matching of 2%. The better the matching of the split termination resistors RTA and RTB, the lower the electromagnetic emission. http://onsemi.com 10 NCV73810V2GEVB Standard Termination Recommended bus split termination is shown in the Figure 7. Considering passive network, without active stars, proper termination should be applied at the two nodes that have the maximum electrical distance on the bus. The sum of termination resistors values should match the nominal cable impedance. At other nodes a high ohmic split termination should be applied. BP FlexRay Bus BM Driver BUS RTA RTB C1 Figure 7.

The function of the common mode choke is to force the current in both signal wires to be of the same strength, but opposite direction. Therefore, the choke represents high impedance for common mode signals. The parasitic stray inductance should be as low as possible in order to keep oscillations on the bus low. The common mode choke is placed between transceiver and split termination [2]. ECU BP RTA BD C1 R1 RTB BM Figure 10. ECU with Split Termination and Common Mode Choke [2] Table 8.
