Device Overview

Summary

The recommended alternative touch controller is ATMXT2912TD-A.

The Microchip's maXTouch® family, known for its superior performance and rich feature set, is now qualified for automotive applications. The mXT3432S-A is optimized for touchscreens up to 17.3" and enables single-layer shieldless designs. In addition to its superior performance, multi-touch functionality, faster response time, robust operation and lower power consumption, the new mXT3432S-A also provides embedded functionalities such as gesture calculation and filter algorithms that meet current automotive design requirements. Dedicated firmware and a high signal-to-noise ratio makes the device ideally suited for very noisy environments and provide full support for gloved-hand operation on automotive touchscreens.
