NCV7381BGEVK evaluation kit provides flexible and convenient
platform to evaluate, characterize and verify the operation of the
NCV7381BDP0R2G FlexRay transceivers.
DESCRIPTION
The NCV7381B is a single−channel FlexRay transceiver compliant
with the FlexRay Electrical Physical Layer Specification Rev. 3.0.1,
capable of communicating at speeds of up to 10 Mbit/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.
NCV7381B mode control functionality is optimized for nodes
permanently connected to car battery.
Additional details can be found in the NCV7381B datasheet.
The NCV7381B0V2GEVB 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
NCV7381B FlexRay transceiver. The design incorporates complete
node solution with possibility of modifications and small board size.
A set of two boards allows users to quickly start with the transceiver
evaluation. The MCU is preprogrammed with simple mode control
and FlexRay communication. The MCU firmware can be freely
modified and reprogrammed if needed.
BOARD HARDWARE
The evaluation board consists of an MCU with integrated 2−channel
FlexRay communication controller interconnected with two separate
FlexRay transceivers (NCV7381B), two switchable voltage regulators
and peripherals. The board is ready for various modifications of power
supply concept and FlexRay bus termination, and allows for simple
extension of the system by unused MCU pins. The USB interface
provides connectivity with standard PC. The address of each board can
be easily modified by address switch what allows for building
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 the NCV7381B evaluation board is populated with several
LEDs and most of the transceiver signals are easily accessible to
oscilloscope probes.
