Overview
The 33897 Series provides a physical
layer for digital communications
purposes using a Carrier Sense
Multiple Access/Collision Resolution
(CSMA/CR) data link operating over a
single wire medium. This is more
commonly referred to as Single Wire
Controller Area Network (CAN).
The 33897 Series operates directly
from a vehicle's 12 V battery system
or a broad range of DC-power
sources. It can operate at either low
or high (33.33 kbps or 83.33 kbps)
data rates. A high voltage wake-up
feature allows the device to control
the regulator used in support of the
MCU and other logic. The device
includes a control pin that can be
used to put the module regulator into
Sleep mode. The presence of a
defined wake-up voltage level on the
bus will reactivate the control line to
turn the regulator and the system
back on.
The device complies with the
GMW3089v2.4 General Motors
Corporation specification.
