Overview
The UJA1168TK,118 is a mini high-speed CAN (Controller Area Network) System Basis Chip (SBC) developed by NXP USA Inc. This component is designed for use in small electronic control units, particularly in body and comfort applications within automotive systems. The UJA1168TK is compliant with ISO 11898-2/5/6 standards and supports both standard CAN 2.0 and CAN FD (Flexible Data Rate) communications. It features an integrated 5 V/100 mA supply for a microcontroller, a watchdog, and a Serial Peripheral Interface (SPI). The chip also includes low-current Standby and Sleep modes with bus and local wake-up capabilities, making it efficient for partial networking scenarios.
