Overview

The UJA1169ATK/FZ is a high-speed CAN System Basis Chip (SBC) featuring an integrated ISO 11898-2:2016 compliant transceiver and a scalable 5V supply for microcontrollers. It supports CAN FD communication up to 5 Mbit/s and includes a second 5V regulator for peripheral components. This device is designed to manage power and communication for automotive electronic control units with minimal external components.

Why Choose This Part

This SBC integrates a watchdog timer and non-volatile memory for configuration, significantly reducing PCB area and software overhead. It offers high robustness with 8 kV HBM ESD protection and short-circuit protection up to 58 V on CAN pins, ensuring reliability in harsh electrical environments.

Applications

Automotive Body Control Modules
Manages power distribution and CAN FD networking for centralized vehicle control units.
Partial Networking ECUs
Utilizes selective wake-up functions to reduce overall vehicle power consumption by keeping inactive nodes in Sleep mode.
Industrial Control Systems
Provides a robust CAN interface and regulated 5V power for industrial sensors and actuators requiring SPI configuration.

Getting Started

To evaluate this part, use the NXP SJA1169 evaluation boards and interface with a microcontroller via the SPI bus for configuration. Ensure the V1 regulator is properly scaled for your MCU load and configure the watchdog settings in the non-volatile memory during initial setup.

Also Consider

TCAN4550-Q1 TITexas Instruments - Includes an integrated CAN FD controller in addition to the transceiver and LDO, allowing CAN FD support via a standard SPI interface.
MCP25625 MCHPMicrochip Technology - A more compact solution that combines a CAN controller and transceiver for space-constrained designs, though with fewer power management features.
