UJA1075TW/3V3,112

Specialized Overview

The UJA1075TW/3V3,118 is a high-speed CAN/LIN core System Basis Chip (SBC) from NXP Semiconductors. It integrates a high-speed CAN transceiver compliant with ISO 11898-2 and ISO 11898-5, and a LIN transceiver compliant with LIN 2.1, LIN 2.0, and SAE J2602. The device includes a scalable 3.3 V voltage regulator delivering up to 250 mA for microcontroller supply, extendable via an external PNP transistor. A separate 5 V regulator powers the on-board CAN transceiver. Additional integrated features include a programmable watchdog, full-duplex SPI interface, two local wake-up input ports, and a limp home output port.

Specialized Feature Summary

• Integrates high-speed CAN and LIN transceivers within a single package
• Provides scalable 3.3 V or 5 V voltage regulation with external current expansion capability
• Features advanced low-power modes including Standby and Sleep with bus wake-up detection
• Includes a programmable watchdog with independent clock source and multiple operating modes

Specialized Applications

• Electronic Control Units (ECU) in automotive applications
• Power and sensor peripheral control networks
• Microcontroller-based systems requiring integrated power management and bus interfaces

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact voltage regulator version and packaging details. Confirm component availability status through authorized distributors as lead times may vary. Ensure all electrical parameters match the system requirements before finalizing procurement orders.

Specialized Selection Notes

Select this component when designing automotive ECUs requiring both high-speed CAN and LIN interfaces alongside integrated power management. Choose the 3.3 V version if the target microcontroller operates at that voltage level. Consider the external PNP transistor option if higher current capacity or improved thermal distribution across the PCB is required for the application.

Specialized Part Context

This component belongs to the UJA1075 family of System Basis Chips designed specifically for automotive electronic control units. It replaces discrete components by combining CAN and LIN physical layers with power regulation and system control functions. The HTSSOP32 package provides a compact solution with low thermal resistance suitable for dense PCB layouts.

Specialized Replacement Considerations

Consult the manufacturer's official cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains compatibility with ISO 11898 and LIN standards while matching the required voltage regulator specifications and pinout configuration.
