The UJA1167ATK is a mini high-speed CAN System Basis Chip containing an ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant HS-CAN transceiver and an integrated 5 V/100 mA supply for a MCU. It also 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 MCU 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 5 V sensor supply (VEXT). This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s.
Several configuration settings are stored in non-volatile memory, allowing the SBC to be adapted for use in a specific application. This makes it possible to configure the power-on behavior of the UJA1167ATK to meet the requirements of different applications.
