The UJA1168ATK is a mini high-speed CAN system basis chip (SBC) containing an ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant HS-CAN transceiver supporting CAN FD up to 5 Mbit/s together with a 5 V/100 mA supply for a microcontroller. It also features a watchdog and a serial peripheral interface (SPI). The UJA1168ATK can be operated in very-low-current standby and sleep modes and supports CAN partial networking by means of a selective wake-up function. A dedicated implementation of the partial networking protocol called “FD-passive” has been embedded as well. A number of configuration settings are stored in non-volatile memory, allowing the SBC to be adapted for use in a specific application.
