Introduction
This document describes the NCV7383EVB Evaluation
board for the ON Semiconductor NCV7383 FlexRay Bus
Driver. The functionality and major parameters can be
evaluated with the NCV7383EVB board.
The NCV7383 is a single-channel FlexRay bus driver
compliant with the FlexRay Electrical Physical Layer
Specification Version 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.
NCV7383 mode control functionality is optimized for
nodes without the need of extended power management
provided by transceivers with permanent connection to the
car battery as is on NCV7381.
NCV7383 is primarily intended for nodes switched off by
ignition. Additional details can be found in the NCV7383
datasheet.

The NCV7383EVB 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 NCV7383 FlexRay bus drivers. The
design incorporates complete node solution with possibility
of modifications and small board size. A set of two boards
allows users immediately start with the NCV7383 FlexRay
Bus Driver. The MCU is preprogrammed with a firmware
which provides simple mode control and FlexRay
communication. With use of Freescalet BDM programmer
and a suitable development environment, the MCU
firmware can be freely modified and reprogrammed.

Board Hardware
The board consists of MCU with integrated 2-channel
FlexRay communication controller interconnected with two
separate FlexRay bus drivers (NCV7383), two voltage
regulators and peripherals. 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 to create complex
FlexRay network without the 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 NCV7383 is populated with
several LED diodes and most of the bus driver signals are
comfortable accessible to oscilloscope probes.
