UJA1167ATK/X/0Z

UJA1167ATK/X/0Z is a mini high-speed CAN system-based chip with standby/sleep modes and watchdog. It 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 and an integrated 5V/100mA supply for a microcontroller. It also features a watchdog and a Serial Peripheral Interface (SPI). The UJA1167A 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. The UJA1167ATK variant contains a battery-related high-voltage output (INH) for controlling an external voltage regulator, while the UJA1167ATK/X is equipped with a 5V sensor supply (VEXT). This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5Mbit/s.
