Time Specification in UJA1169A

Contributor I


We are using UJA1169ATK3 and would like to know certain timing specification.

  1. Time taken for switching between modes of SBC like from Power off to RESET to Standby,
  2. Time taken for from Standby mode to Normal mode and from Normal mode to Standby mode after it is configured to the respective mode via SPI communication.
  3. What would be the state of CAN line, RST pin, Limp, Watchdog and any other specific changes during the transition time(Normal to standby and vice-versa).
  4. I was able to see, that tstartup(CAN) in datasheet, I assume that this is the time taken for CAN to be able to communicate from the instant CAN is configured to be in active mode after SBC is configured to Normal mode.

We will not be using the SBC sleep mode or the wakeup functionality of CAN.

Please provide clarifications for the above.
