Technical Data
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.
Features
• Waveshaping for Low Electromagnetic Interference (EMI)
• Detects and Automatically Handles Loss of Ground
• Worst-Case Sleep Mode Current of Only 60 µA
• Current Limit Prevents Damage Due to Bus Shorts
• Built-In Thermal Shutdown on Bus Output
• Protected Against Vehicular Electrical Transients
• Undervoltage Lockout Prevents False Data with Low Battery
• Pb-Free Packaging Designated by Suffix Code EF

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.

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.

Battery
Power input. An external diode is needed for reverse battery protection.

Load
The external bus load resistor connects here to prevent bus pullup in the
event of loss of module ground.

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.

7. GMW3089V2.4 specifies the maximum load voltage rise to be 0.1 V whenever module battery is intact, including when in Sleep mode.
The maximum load voltage rise of 1.0 V in Sleep mode is a GM-approved exception to GMW3089V2.4.
8. 33897A/B/C/D remove diode drop during Sleep mode.
9. LOAD terminal is at system ground voltage.
