Table 1. CAN FD Controller Interface
Symbol Description 1 Min Max Units
FCAN_FD_REFCLK 2 CAN FD reference clock frequency 1x 80 MHz
CAN FD reference clock frequency 2x 160 MHz

  1. The test conditions are configured to the LVCMOS 3.3V I/O standard with a 12 mA drive strength, fast slew rate, and a 15 pF load.
  2. The APB interface (LPD_LSBUS_CLK) operating frequency must be greater than or equal to the CAN FD operating frequency (which is the CAN_FD_REFCLK frequency divided by the CAN[0|1]_REF_CTRL[DIVISOR]).
