Single Wire CAN Transceiver
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 terminal 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.

Electrical Common Ground and Heat removal. A good thermal path
will also reduce the die temperature.

TXD
Transmit Data
Data input here will appear on the BUS terminal. A logic [0] will assert
the bus, a logic [1] will make the bus go to the recessive state.

Mode Control
These Pins control Sleep Mode, Transmit Level, and Speed. They

RXD
Receive Data
Open drain output of the data on BUS. A recessive bus = a logic [1], a
dominant bus = logic [0]. An external pullup is required.

No Connect
No internal connection to these Pins. Pin 13 can be connected to GND
to allow the use of the 14-terminal or 8-terminal device. (1)

Battery
Power input. An external diode is needed for reverse battery
protection.
11 6 LOAD
Load
The external bus load resistor connects here to prevent bus pullup in
the event of loss of module ground.
12 7 BUS
Bus This terminal connects to the bus through external components.
Notes
1. Module boards can be planned for the 14-terminal package and still use the 8-terminal package.
