UJA1061TW/5V0/C/T,

Specialized Overview

The UJA1061TW/5V0/C/T is a fault-tolerant CAN/LIN fail-safe System Basis Chip (SBC) manufactured by NXP Semiconductors. It integrates a microcontroller voltage regulator, a dedicated CAN transceiver regulator, and an advanced watchdog with an on-chip oscillator into a single HTSSOP32 package. The device supports 14 V, 24 V, and 42 V automotive architectures. Key electrical parameters include a minimum operating voltage of 5.5 V, maximum supply voltages of 27 V and 52 V, and an operating temperature range from -40 °C to +125 °C. It features a full-duplex SPI interface for system control and status reporting.

Specialized Feature Summary

• Integrates ISO 11898-3 compliant fault-tolerant CAN transceiver and LIN 2.0 transceiver within a single package.
• Provides intelligent power management with independent voltage regulators for the microcontroller and CAN transceiver.
• Ensures safe operation through a programmable fail-safe coded window and time-out watchdog with on-chip oscillator.
• Supports remote flash programming via the CAN-bus and includes detailed status reporting on system and subsystem levels.

Specialized Applications

• Electronic Control Units (ECUs) utilizing fault-tolerant CAN as the main network interface.
• Automotive networking applications requiring a local sub-bus via LIN.
• Systems designed for 14 V, 24 V, or 42 V single and dual power supply architectures.

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required voltage version and packaging format. Check for end-of-life status or obsolescence notices prior to procurement planning. Ensure compliance with RoHS directives and relevant automotive standards for the intended deployment environment.

Specialized Selection Notes

Select the UJA1061TW/5V0 variant when a 5.0 V output is required for the microcontroller supply. Verify compatibility with the target microcontroller's CAN controller integration. Evaluate the need for 42 V architecture support if BAT42 pin usage is necessary. Consider the HTSSOP32 package dimensions and thermal requirements for the printed-circuit board layout.

Specialized Part Context
