UJA1169TK/3Z

Specialized Overview

The UJA1169TK/3Z is a mini high-speed CAN System Basis Chip (SBC) from NXP Semiconductors. It integrates an ISO 11898-2:201x compliant HS-CAN transceiver supporting active CAN FD communication up to 2 Mbit/s, and a scalable 3.3 V microcontroller supply (V1) with 250 mA output current capability. The device includes a watchdog timer, Serial Peripheral Interface (SPI), and a dedicated second on-board 5 V regulator (V2) for internal CAN transceiver power. It operates in low-current Standby and Sleep modes with bus and local wake-up capabilities.

Specialized Feature Summary

• Integrates a high-speed CAN transceiver compliant with ISO 11898-2:201x standards.
• Features a scalable 3.3 V low-drop voltage regulator for microcontroller supply.
• Includes a dedicated 5 V on-board regulator for internal CAN transceiver power.
• Supports autonomous bus biasing and partial networking functions.

Specialized Applications

• Automotive general-purpose electronic control units
• Body control modules requiring integrated power management
• Sensor nodes utilizing CAN FD communication

Specialized Procurement Notes

Verify the specific ordering suffix '3Z' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required host microcontroller interface and voltage levels before finalizing procurement orders.

Specialized Selection Notes

Select this variant when a 3.3 V microcontroller supply is required alongside a dedicated 5 V rail for the internal transceiver. Confirm that the application does not require off-board sensor supplies, as this model lacks the VEXT pin found in '/X' variants.

Specialized Part Context

This component belongs to the UJA1169 family of mini high-speed CAN system basis chips. It is commonly utilized in automotive evaluation boards, such as those based on the S32K144 MCU, to provide integrated CAN connectivity and power regulation for body electronics applications.

Specialized Replacement Considerations

Compatible substitutes within the same family include UJA1169TK/F/3Z, which offers partial networking support, or UJA1169TK/3, which uses cut-tape packaging instead of reel packaging.
