ATMXT112S-MA5UR024

Overview

The ATMXT112S-MA5UR024 is a single-chip capacitance touch controller from Microchip Technology's maXTouch M1 series. It provides up to 112 reconfigurable touch channels, supporting displays up to 20 inches in 16:9 format or 34 inches in 7:1 aspect ratio. The device integrates firmware authentication for secure Over-the-Air updates compliant with ISO 21434:2021 and meets ASIL-A/B functional safety standards under ISO 26262. It operates within a voltage range of 1.8 V to 3.3 V and supports an operating temperature range of -40°C to +85°C.

Feature Summary

Supports large, curved, and free-form touch displays with high channel density.
Integrates firmware authentication to enable reliable Over-the-Air updates.
Complies with automotive functional safety standards (ASIL-A/B).

Applications

Automotive infotainment systems requiring certified functional safety.
Large-format consumer display interfaces.
Curved or free-form touchscreen applications.

Procurement Notes

Verify the specific ordering suffix MA5UR024 against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing I2C or USB interface configurations before procurement. Cross-reference the part number with current product change notifications to verify manufacturing status and availability constraints.

Selection Notes

Select this component when designing systems requiring ISO 26262 compliance and secure OTA capabilities. The 112-channel capacity suits medium-to-large display sizes. Verify that the host system can support the required voltage levels and thermal conditions within the specified operating range.

Part Context

This part belongs to the maXTouch M1 series, designed for high-performance capacitive touch sensing. It replaces older generations by integrating advanced security features and functional safety certifications directly into the controller silicon, suitable for modern automotive and premium consumer electronics.

Replacement Considerations

Consult Microchip's official obsolescence notices for confirmed substitutes. Generic equivalents may lack the specific ASIL certification or firmware authentication mechanisms required for this application.
