FUNCTIONAL DESCRIPTION

FUNCTIONAL PIN DESCRIPTION

CAN LOW (CANL)

This is the CAN Low input/output pin. CANL circuitry is

design to work as a low side switch connected to GND. In the

recessive state, this switch is turned off and CANL is then

biased to SPLIT voltage or Gnd, depending on device’s

operating state. In the dominant state, the switch is turned on

and CANL is biased to GND voltage. The CANL pin is

protected and diagnostics reporting is available against short

to Battery, Gnd, and 5.0 V (VDD).

STANDBY (STBY)

This is the standby input pin for device static mode control.

This pin is connected to the MCU to place transceiver in the

desired mode. Functional voltage thresholds are determined

by VIO voltage to accommodate the implementation of 3.3 V

or 5.0 V MCUs. CLK (Clock) during Pseudo SPI

communication.
