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.
