MC33897CTEFR2

MC33897CTEFR2 is a 33897 series single wire CAN transceiver. It 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. It is more commonly referred to as a single-wire Controller Area Network (SWCAN). It operates directly from a vehicle's 12V battery system or a broad range of DC-power sources. It can operate at low or high (33.33kbps or 83.33kbps) 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.

• Wave shaping for low Electromagnetic Interference (EMI)
