UJA1075ATW/5V0,118

Specialized Overview

The UJA1075ATW/5V0,118 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 standards, and a LIN transceiver supporting LIN 2.0 through 2.2A. The device includes a scalable 5 V main voltage regulator (V1) delivering up to 250 mA for microcontroller supply, and a separate 5 V voltage regulator (V2) dedicated to the on-board CAN transceiver. Communication with the host microcontroller is facilitated via a full-duplex Serial Peripheral Interface (SPI). The component operates within a battery supply range of 4.5 V to 28 V and is housed in a 32-lead HTSSOP package.

Specialized Feature Summary

• Integrates high-speed CAN and LIN transceivers with enhanced EMC performance and ESD protection.
• Features independent voltage regulators for microcontroller and CAN bus power management.
• Supports advanced low-power modes including Standby and Sleep with wake-up detection capabilities.
• Provides detailed system status reporting and diagnostic features via SPI interface.

Specialized Applications

• Electronic Control Units (ECU) requiring integrated CAN/LIN communication and power management
• Automotive sensor peripheral control networks
• Power distribution units in vehicle body electronics

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product data sheet to confirm pinout compatibility and regulatory compliance status. Ensure that the selected variant matches the required voltage regulator output and watchdog functionality for the target application design.

Specialized Selection Notes

Select this variant when a 5 V output is required for the microcontroller supply rail. Compare against the 3.3 V version if lower voltage regulation is needed. Confirm whether the integrated watchdog timer is necessary; if not, variants without the 'W' suffix may be considered, though this specific part includes standard SBC features.

Specialized Part Context

This component belongs to the UJA1075A family of System Basis Chips designed for automotive applications. It replaces discrete components typically found in ECUs by combining communication interfaces and power management into a single package. The family offers variations in output voltage and feature sets to suit different microcontroller requirements.

Specialized Replacement Considerations

Direct substitutes include other UJA1075A variants such as UJA1075ATW/3V0 or UJA1075ATW/5V0WD depending on voltage and watchdog needs. Cross-family replacements require careful evaluation of pin compatibility and register mapping differences.
