ATA663231-GBQW-VAO

Specialized ICS Overview

The ATA663231-GBQW-VAO is an automotive-grade LIN System Basis Chip (SBC) manufactured by Microchip Technology. It integrates a LIN transceiver with a 3.3V low-dropout regulator, designed for robust communication in vehicle networks. The device operates within a supply voltage range of 5 V to 28 V and supports data rates up to 20 kBd. It features a propagation delay of 6 µs and functions reliably across an extended temperature range from -40°C to +150°C. Packaged in an exposed pad 8-VDFN (3x3 mm) format with wettable flank capability, it meets AEC-Q100 qualification standards for automotive reliability.

Specialized ICS Feature Summary

• Integrated LIN transceiver with 3.3V LDO regulator
• AEC-Q100 qualified for automotive applications
• 8-VDFN package with wettable flank for enhanced inspection
• Wide operating voltage range: 5 V to 28 V

Specialized ICS Applications

• Automotive LIN network nodes
• Body control modules
• Sensor and actuator interfaces in vehicles

Specialized ICS Procurement Notes

Verify the specific ordering suffix GBQW-VAO against the manufacturer's current datasheet to confirm pinout, regulatory compliance, and packaging details. Confirm availability status directly with authorized distributors or the manufacturer, as stock levels fluctuate. Ensure the procurement channel provides valid traceability documentation required for automotive component sourcing.

Specialized ICS Selection Notes

Select this component when a 3.3V regulated output is required alongside LIN communication in automotive environments. Compare with the ATA663254 variant if a 5V regulator is needed instead. Verify that the 8-VDFN footprint matches the PCB design constraints. Ensure the application environment stays within the specified -40°C to +150°C operating temperature range.

Specialized ICS Part Context

This part belongs to the Microchip ATA6632xx family of LIN System Basis Chips. It shares the same physical interface and core LIN transceiver functionality as other members like the ATA663254, differing primarily in the integrated voltage regulator output level. The family is designed to reduce component count and board space in automotive electronic control units.

Specialized ICS Replacement Considerations

The ATA663254-GBQW-VAO is a functional alternative within the same package if a 5V regulator is acceptable. Verify pin compatibility and regulator specifications before substitution. No other direct cross-model replacements are confirmed in public documentation.
