FlexRay™ Transceiver With Wakeup
[attachment=39789]
Features
Part of the FlexRay™ electrical, physical layer
Interface between communication controller
and physical medium (twisted pair bus line)
Support of data rates up to 10 Mbit/s
Support of low power mode for an ECU
Remote wake-up via bus line
Enhanced diagnosis capability via SPI
with interrupt generation
Protection against overload damage by current
limitation and overtemperature detection
Bus driver
Brief Functional Description
The low cost bus driver is a part of the electrical, physical
layer in a FlexRay™ communication network. The
E910.55 provides an interface between the twisted pair
physical bus medium and a communication controller
(CC). An SPI interface connects the bus driver (BD) to
a host controller (HOST) to provide status information
concerning failure detection on the bus lines (e.g.
short-circuits, ground loss) and overtemperature condition.
An interrupt signal is generated whenever the
failure status changes.
The device supports normal and standby modes and
provides remote wake up capability via bus line. The
output (INH) can be used to control an external voltage
regulator.
