The UJA1167ATK 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 and an integrated 5 V/100 mA supply for a microcontroller. It features a watchdog and a serial peripheral interface (SPI). The UJA1167ATK can be operated in very-low-current standby and sleep modes with bus and local wake-up capability and supports ISO 11898-2:2016 compliant autonomous CAN biasing. The microcontroller supply is switched off in sleep mode. A number of configuration settings are stored in non-volatile memory, allowing the SBC to be adapted for use in a specific application.
