Overview
The UJA1164ATK/0Z, produced by NXP USA Inc., is a mini high-speed CAN System Basis Chip (SBC) designed specifically for automotive applications. This chip integrates an ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant high-speed CAN (HS-CAN) transceiver along with a 5 V/100 mA supply for microcontrollers. It features a watchdog, a Serial Peripheral Interface (SPI), and operates in a very-low-current Standby mode with bus wake-up capability. The device supports data rates up to 5 Mbit/s in CAN FD fast phase and offers autonomous CAN biasing, making it highly suitable for reliable communication in vehicle networks.
