Firmware updates are supported via the vehicle's main computer with integrated authentication verification.

Feature Summary

• Supports up to 112 reconfigurable touch channels or 162 equivalent channels in ultrawide mode
• Compatible with large, curved, and free-form displays up to 20" (16:9) and 34" (7:1)
• Meets ASIL-A/B functional safety standards per ISO 26262
• Features integrated firmware authentication and update capabilities

Applications

• Automotive infotainment systems requiring large display support
• Curved or free-form touchscreen interfaces in vehicles
• Safety-critical human-machine interaction (HMI) modules

Procurement Notes

Verify the specific suffix ARVAO against official Microchip documentation to confirm package type, temperature range, and tape-and-reel specifications. Ensure compatibility with existing system firmware for authenticated updates. Confirm supply chain status directly with authorized distributors as availability may vary.

Selection Notes

Select this component when designing for automotive-grade capacitive touch solutions requiring high channel counts and functional safety certification. Compare against other M1 series variants like ATMXT2496M1 if lower channel density suffices. Validate that the target display dimensions fit within the supported 20-inch 16:9 or 34-inch 7:1 form factors.

Part Context

This part belongs to the maXTouch M1 series, an expansion of Microchip's automotive touchscreen portfolio. It complements earlier generations like the TD and UD series by offering enhanced safety features and larger channel capacity suitable for modern vehicle interiors.

Replacement Considerations

Check for direct substitutes within the M1 series such as ATMXT2496M1 for reduced channel needs. Verify pin-to-pin compatibility and firmware equivalence before replacing legacy parts like those from the TD or UD series.
