ATMXT2952TD-C2URKD1

Overview

The ATMXT2952TD-C2URKD1 is a maXTouch touchscreen controller featuring a charge-transfer acquisition engine for high-accuracy multi-touch tracking. It supports up to 41 X and 71 Y lines, allocating a maximum of 2911 nodes for sensors or keys. The device operates on a 3.3V digital supply with 1.8V to 3.3V I/O levels and an external XVdd up to 9.2V. Interfaces include I2C (up to 3.4 MHz) and USB HID. It provides simultaneous mutual and self-capacitance measurements, supporting up to 16 concurrent touches with a typical report rate of ≥110 Hz.

Feature Summary

• Supports up to 2911 nodes across 41 transmit and 71 receive lines for large displays.
• Enables 16 concurrent touch tracking with initial latency under 20 ms.
• Includes moisture compensation for water drops up to 22 mm diameter.
• Features encrypted configuration parameters and touch coordinate reports using customer security keys.

Applications

• Industrial displays ranging from 12.1 to 23.8 inches.
• On-cell and touch-on-display implementations for OLED and LCD panels.
• Discrete out-cell sensor applications using glass or PET film materials.

Procurement Notes
