UJA1069TW24/5V0/C:

Specialized Overview

The UJA1069TW24/5V0/C is a LIN fail-safe System Basis Chip (SBC) from NXP Semiconductors, designed for automotive Electronic Control Units. It integrates a LIN transceiver compliant with LIN 2.0 and SAE J2602, a dedicated 5.0 V voltage regulator for the microcontroller, an enhanced window watchdog with an on-chip oscillator, and a full-duplex Serial Peripheral Interface. The device supports 14 V and 42 V power supply architectures and features local wake-up inputs, inhibit/limp-home outputs, and advanced low-power modes. It is housed in a compact HTSSOP24 package.

Specialized Feature Summary

• Integrates a LIN transceiver compliant with LIN 2.0 and SAE J2602 standards.
• Includes a dedicated 5.0 V voltage regulator for microcontroller power supply.
• Features an enhanced window watchdog with an on-chip oscillator for system supervision.
• Provides a full-duplex SPI interface for configuration and status reporting.

Specialized Applications

• Automotive electronic control units requiring LIN bus communication.
• Systems utilizing 14 V or 42 V single/dual power supply architectures.
• Applications demanding advanced fail-safe behavior and low-power management.

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Ensure storage conditions meet semiconductor handling guidelines to prevent moisture damage. Check for obsolescence notices as availability may vary. Validate pin compatibility with target PCB layouts before integration.

Specialized Selection Notes

Select this component for applications requiring integrated LIN communication and power management in a small form factor. Consider the HTSSOP24 package constraints for thermal dissipation. Evaluate the need for 42 V architecture support versus standard 14 V systems. Assess software complexity regarding the fail-safe state machine and watchdog implementation requirements.

Specialized Part Context

This part belongs to the UJA1069 family of LIN fail-safe System Basis Chips. It is specifically the TW24 variant, indicating the HTSSOP24 package type. The suffix /5V0/C typically denotes the voltage regulator output and commercial temperature grade, consistent with NXP naming conventions for this series.

Specialized Replacement Considerations

Direct replacements within the same family include the UJA1069TW (HTSSOP32 package). Verify pinout compatibility between HTSSOP24 and HTSSOP32 variants if considering package changes. No other specific substitute part numbers are confirmed in public documentation.
