ATMXT2952TD-C2U002

Overview

The ATMXT2952TD-C2U002 is a maXTouch 2911-node touchscreen controller from Microchip Technology, designed for high-performance capacitive sensing. It supports up to 41 X and 71 Y lines, enabling tracking of up to 16 concurrent touches with a typical report rate of ≥110 Hz. The device integrates I²C and USB HID interfaces for host communication. It operates within an industrial temperature range of –40°C to +85°C and utilizes a 162-ball UFBGA package measuring 10 × 5 × 0.6 mm.

Feature Summary

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

Applications

• On-cell and touch-on-display solutions for OLED and LCD panels.
• Discrete or out-cell sensor implementations using glass or PET film materials.
• Industrial and commercial displays requiring robust noise suppression and stylus support.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's product identification system to confirm packaging type. The C2U002 designation indicates supply in trays, whereas the C2UR002 variant is supplied in tape and reel. Confirm that the selected part number aligns with the required manufacturing assembly process before procurement.

Selection Notes

Select this component for designs requiring extensive node allocation and advanced gesture recognition. Ensure the host interface matches the supported I²C modes (up to 3.4 MHz) or USB HID requirements. Verify that the application environment remains within the specified –40°C to +85°C operating temperature range for industrial grade performance.

Part Context

This device belongs to the ATMXT2952TD family, utilizing firmware revision 2.0.AA. It is distinct from automotive-qualified variants and is classified as industrial grade. The part number structure includes specific identifiers for the package type, temperature range, and pattern requirements defined by Microchip.

Replacement Considerations

The ATMXT2952TD-C2UR002 serves as a functional equivalent with identical electrical characteristics but differs in packaging format. The C2UR002 is supplied in tape and reel, suitable for automated surface-mount assembly, while the C2U002 is provided in trays.
