ATMXT2113TD-ABRKDVA1

Overview

The ATMXT2113TD-ABRKDVA1 is an automotive-grade touchscreen controller from Microchip Technology, belonging to the maXTouch M1 series. It integrates up to 2112 reconfigurable touch nodes within a single chip, supporting large display formats including 20-inch 16:9 and 34-inch 7:1 screens. The device operates with a maximum supply voltage of 3.47 V and supports I2C and SPI interfaces. Designed for automotive environments, it functions reliably across a temperature range of -40°C to +85°C and is housed in a 144-pin LQFP package.

Feature Summary

• High node density with up to 2112 reconfigurable touch channels for complex display configurations.
• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle applications.
• Dual interface support enabling flexible integration via I2C or SPI communication protocols.
• Integrated firmware authentication mechanism to ensure secure Over-the-Air (OTA) updates.

Applications

• Automotive infotainment systems requiring high-resolution touch input.
• Large curved or free-form touch displays in vehicle dashboards.
• Digital instrument clusters with advanced gesture recognition capabilities.

Procurement Notes

Verify the specific suffix 'ABRKDVA1' against official Microchip documentation to confirm exact packaging, tape-and-reel specifications, and regional availability. Confirm RoHS compliance status through the manufacturer's product compliance database prior to procurement. Ensure the ordering quantity aligns with the factory reel pack size specified in the datasheet.

Selection Notes

Select this component when designing automotive displays requiring extensive touch node counts exceeding standard controllers. Verify that the host system supports the required I2C or SPI clock speeds and voltage levels compatible with the 3.47 V maximum supply. Ensure the PCB layout accommodates the LQFP-144 package dimensions and thermal requirements for the specified operating temperature range.

Part Context

This part belongs to the maXTouch M1 series, which expands Microchip's portfolio of single-chip touchscreen controllers. The series is engineered to meet ASIL-A/B functional safety standards under ISO 26262. It replaces older generations by offering higher channel density and enhanced cybersecurity features for modern automotive HMI designs.

Replacement Considerations

Cross-reference with other ATMXT2113 variants to determine if different suffixes offer alternative packaging or temperature grades. Verify pin-to-pin compatibility before substituting with non-Microchip solutions, as firmware architecture differences may require significant redesign.
