Technical Data

Single Wire CAN Transceiver

33897

The 33897 series provides a physical layer for digital

communication 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 (SWCAN).

SINGLE-WIRE CAN

TRANSCEIVER

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 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.
