UJA1169ATK/XZ

Specialized Overview

The UJA1169ATK/XZ is a mini high-speed CAN System Basis Chip (SBC) from NXP Semiconductors. It integrates an ISO 11898-2:2016 and SAE J2284 compliant HS-CAN transceiver supporting CAN FD active communication up to 5 Mbit/s. The device includes a scalable 5 V or 3.3 V, 250 mA low-drop voltage regulator (V1) for microcontroller supply. It features a watchdog timer, Serial Peripheral Interface (SPI), and local wake-up capability. The variant supports very low-current Standby and Sleep modes with bus and local wake-up functionality.

Specialized Feature Summary

• Integrates a high-speed CAN transceiver compliant with ISO 11898-2:2016 and SAE J2284 standards, supporting CAN FD data rates up to 5 Mbit/s.
• Includes a scalable 5 V or 3.3 V, 250 mA low-drop voltage regulator (V1) designed for microcontroller power supply with thermal scaling capabilities.
• Features autonomous bus biasing and CAN-bus connections that remain floating when the BAT pin power is off.
• Provides robust protection including ±8 kV ESD on CAN pins, short-circuit proof CAN pins to ±58 V, and protection against automotive transients per ISO 7637-3.

Specialized Applications

• Automotive electronic control units requiring high-speed CAN communication
• Systems utilizing CAN FD protocols for enhanced data throughput
• Microcontroller power supply integration in compact automotive modules

Specialized Procurement Notes

Verify the specific ordering suffix 'Z' against the official NXP datasheet to confirm package type, tape and reel specifications, and environmental compliance status. Ensure the selected variant matches the required voltage regulator configuration (5 V vs 3.3 V) and supply options (VEXT) for your application design.

Specialized Selection Notes

Select this component if your design requires a mini high-speed CAN SBC with integrated CAN FD support up to 5 Mbit/s. The UJA1169ATK/XZ variant specifically provides a protected off-board sensor supply (VEXT) suitable for external components. Consider the low quiescent current in Standby and Sleep modes for power-sensitive automotive applications.

Specialized Part Context

The UJA1169A series comprises six variants differentiated by their voltage regulators and additional supply options. The UJA1169ATK/XZ belongs to the group equipped with a 5 V supply (VEXT) for off-board components, distinguishing it from variants with internal CAN supply (V2). This family is designed for hardware and software compatibility within the UJA1169 product line.

Specialized Replacement Considerations

Direct replacements within the UJA1169A family include UJA1169ATK/FZ, UJA1169ATK/3Z, and UJA1169ATK/F/3Z, depending on whether partial networking or different voltage regulator outputs are required. Verify pin compatibility and specific feature sets like CAN FD passive support before substitution.
