ATMXT2952TD-C2UR001

Overview

The ATMXT2952TD-C2UR001 is a maXTouch touchscreen controller from Microchip Technology, designed for high-performance capacitive sensing. It supports up to 2911 X/Y nodes and tracks up to 16 concurrent touches with a typical report rate of ≥100 Hz. The device integrates I²C (up to 3.4 MHz) and USB HID interfaces. Power requirements include nominal 3.3V for digital/analog supplies and 1.8V to 3.3V for I/O. It operates within an industrial temperature range of –40°C to +85°C and is housed in a 162-ball UFBGA package measuring 10 × 5 × 0.6 mm.

Feature Summary

• Supports up to 2911 nodes with 16 concurrent touch tracking and gesture recognition
• Integrated I²C slave interface supporting speeds up to 3.4 MHz and USB HID interface
• Advanced noise suppression handling up to 240 V PP ambient noise and water compensation
• Includes lens bending algorithms and palm recovery for display integration

Applications

• Industrial displays ranging from 12.1 to 23.8 inches
• On-cell and touch-on-display solutions for TFT, IPS, and OLED panels
• Mid-sized displays requiring compliance with EMC evaluation criteria

Procurement Notes

Verify the C2U suffix indicates tape and reel packaging as specified in the product identification system. Confirm firmware revision 1.0.AA compatibility during sourcing. Ensure procurement channels provide official Microchip documentation for the specific ordering code.

Selection Notes

Select this component for designs requiring extensive node counts up to 2911. Verify that the host system supports either I²C or USB HID communication protocols. Ensure power rails can supply 3.3V for AVdd/Vdd and 1.8V-3.3V for VddIO. Check that the PCB layout accommodates the 162-ball UFBGA footprint.

Part Context

This part belongs to the mXT2952TD series, utilizing charge-transfer acquisition technology. It is distinct from automotive-grade variants and is intended for general industrial and commercial applications. The 'R' suffix specifically denotes the tape and reel packaging option.

Replacement Considerations
