ATA6571-GCQW0-VAO

Drivers, Receivers, Transceivers Overview

The ATA6571-GCQW0-VAO is a Grade 0 high-speed CAN FD transceiver designed for automotive applications, supporting communication speeds up to 5 Mbps. It complies with ISO 11898-2, ISO 11898-5, and SAE J2962-2 standards. The device operates within an ambient temperature range of -40°C to +150°C and features a dedicated High-Voltage WAKE input pin for local wake-up capabilities. It includes remote wake-up detection via the CAN bus according to ISO 11898-2: 2016 specifications.

Drivers, Receivers, Transceivers Feature Summary

• Supports CAN FD protocols with high electromagnetic compatibility and electrostatic discharge protection on bus pins.
• Features a dedicated high-voltage WAKE input pin for flexible local wake-up circuit design.
• Provides advanced low-power management with multiple operating modes including Sleep, Standby, Silent, and Normal.
• Includes comprehensive diagnostic flags accessible through the NERR pin for system health monitoring.

Drivers, Receivers, Transceivers Applications

• High-speed Controller Area Network (CAN) node implementation in automotive environments.
• Systems requiring robust local wake-up functionality via external switches connected to the WAKE pin.
• Applications demanding extended temperature operation up to +150°C ambient conditions.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'GCQW0' against the manufacturer's current product identification system to confirm package type and grade availability. Ensure that the 'VAO' suffix aligns with the required manufacturing origin or lifecycle status as defined by Microchip Technology documentation prior to finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when an ambient temperature rating up to +150°C is required, distinguishing it from the Grade 1 variant which supports up to +125°C. Confirm that the application utilizes the High-Voltage WAKE pin for local wake-up events rather than relying solely on remote bus wake-up patterns. Verify voltage levels for VCC and VIO match the microcontroller interface requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ATA6571 family of CAN FD transceivers manufactured by Microchip Technology. The family includes Grade 1 variants such as the ATA6571-GNQW1, which share similar functional architectures but differ in maximum ambient temperature ratings. The ATA6571 series is designed to meet OEM hardware requirements for automotive CAN applications.

Drivers, Receivers, Transceivers Replacement Considerations

The ATA6571-GNQW1 serves as a functional substitute within the same family, offering identical electrical characteristics and pinouts. The primary distinction lies in the thermal grade; the GNQW1 variant supports a maximum ambient temperature of +125°C compared to the +150°C limit of the GCQW0 variant.
