UJA1065TW/5V0,518

Specialized Overview

The UJA1065TW/5V0,518 is a high-speed CAN/LIN fail-safe System Basis Chip (SBC) manufactured by NXP Semiconductors. It integrates a high-speed CAN transceiver compliant with ISO 11898-2 and ISO 11898-5, alongside a LIN transceiver compliant with LIN 2.0 and SAE J2602. The device includes dedicated voltage regulators for the microcontroller (5 V version) and CAN transceiver, an advanced independent watchdog with an on-chip oscillator, and a full-duplex Serial Peripheral Interface (SPI). Designed for automotive Electronic Control Units (ECUs), it supports 14 V and 42 V power architectures. Key features include local wake-up inputs, inhibit/limp-home outputs, and detailed status reporting to ensure safe system start-up and fail-safe behavior.

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment upon receipt. Check for moisture sensitivity level compliance prior to soldering. Ensure ordering suffix matches required voltage regulator output. Validate datasheet revision against manufacturing date code for functional consistency.

Specialized Selection Notes

Select the UJA1065TW/5V0 variant when a 5 V microcontroller supply is required. Verify compatibility with existing CAN transceiver standards such as TJA1041. Ensure the HTSSOP32 package fits the PCB footprint constraints. Confirm that the application requires integrated LIN functionality alongside high-speed CAN. Evaluate power architecture needs for 14 V or 42 V single/dual supply systems.

Specialized Part Context

The UJA1065 series serves as a comprehensive solution for automotive ECUs, replacing discrete components with a single integrated chip. It combines essential networking interfaces with power management and safety features. The TW/5V0 designation specifies the 5 V regulator version housed in an HTSSOP32 package. This component is part of NXP's broader portfolio of system basis chips designed for robust automotive electronics.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with legacy CAN transceivers like TJA1041 if integrating into existing designs. Consult NXP technical support for alternative components if this specific variant is discontinued.
