UJA1061TW/5V0/C/T/

Specialized Overview

The UJA1061TW/5V0/C/T/ is a fail-safe System Basis Chip (SBC) from NXP Semiconductors designed for automotive Electronic Control Units. It integrates a fault-tolerant CAN transceiver compliant with ISO 11898-3, a LIN transceiver compliant with LIN 2.0 and SAE J2602, and dedicated voltage regulators for the microcontroller (5 V) and CAN transceiver (5 V). The device supports 14 V, 24 V, and 42 V power architectures and features an advanced watchdog with an on-chip oscillator. It utilizes a 32-lead HTSSOP package with an exposed thermal pad.

Specialized Feature Summary

• Integrates fault-tolerant CAN and LIN transceivers with independent voltage regulation
• Provides autonomous fail-safe system supervision via programmable window and time-out watchdog
• Supports multiple low-power operating modes including Standby and Sleep with cyclic wake-up capabilities
• Features detailed status reporting and failure detection through a fail-safe coded SPI interface

Specialized Applications

• Automotive Electronic Control Units requiring fault-tolerant CAN communication
• Systems utilizing LIN as a local sub-bus for peripheral control
• Applications demanding intelligent power management and safe start-up behavior
• Network nodes requiring partial networking and global wake-up features

Specialized Procurement Notes

Verify component authenticity by checking the manufacturer's marking code against official documentation. Confirm the specific ordering suffix matches the required voltage regulator version. Ensure the package type corresponds to the intended PCB layout requirements. Validate that the device revision aligns with the design specifications before integration into production systems.

Specialized Selection Notes

Select this component when a combined CAN/LIN interface with integrated power management is required. Choose the 5 V version if the microcontroller supply voltage requirement is 5 V rather than 3.3 V. Consider the HTSSOP32 package dimensions for space-constrained designs. Evaluate the need for 42 V architecture support versus standard 14 V systems during the initial design phase.

Specialized Part Context

This part belongs to the UJA1061 family of System Basis Chips. Variants such as UJA1061TW/3V3/C/T/ provide a 3.3 V microcontroller regulator instead of 5 V. The family is designed to replace discrete components in ECUs, offering a compact solution for automotive networking applications with integrated safety features.

Specialized Replacement Considerations

Direct substitutes within the same family include the UJA1061TW/3V0/C/T/ variant which differs only in the microcontroller output voltage. Cross-family replacements require careful evaluation of pin compatibility and feature sets. Verify that alternative devices support the same fault-tolerant CAN and LIN standards.
