UJA1065TW/5V0/512

Specialized Overview

The UJA1065TW/5V0/512 is a fail-safe System Basis Chip (SBC) from NXP Semiconductors, designed for automotive Electronic Control Units (ECUs). It integrates a high-speed CAN transceiver compliant with ISO 11898-2 and a LIN transceiver compliant with LIN 2.0. The device includes dedicated voltage regulators providing 5.0 V for the microcontroller and 5.0 V for the CAN transceiver. It supports 14 V and 42 V power supply architectures and features an advanced independent watchdog with an on-chip oscillator. The component operates within a temperature range of -40 °C to +125 °C and is housed in a 32-lead HTSSOP package.

Specialized Feature Summary

• Integrates high-speed CAN and LIN transceivers with fail-safe system supervision
• Provides dedicated regulated power supplies for both the microcontroller and the CAN transceiver
• Features an autonomous fail-safe controller with detailed status reporting and error detection
• Supports multiple low-power operating modes including Standby and Sleep with cyclic wake-up capabilities

Specialized Applications

• Automotive Electronic Control Units (ECUs)
• Network applications utilizing high-speed CAN as the main interface
• Local sub-bus systems using LIN communication
• Power and sensor peripheral control modules

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout compatibility and regulatory compliance status. Confirm that the 5 V regulator version matches the target microcontroller requirements. Check for any obsolescence notices or recommended replacement components if the part is no longer actively manufactured.

Specialized Selection Notes

Select this component when a single-chip solution is required for integrating CAN, LIN, and power management functions. Ensure the design utilizes a 14 V or 42 V architecture compatible with the BAT14 and BAT42 inputs. Verify that the microcontroller supports SPI communication for configuration and that the HTSSOP32 package fits the PCB layout constraints.
