ATMXT1664T3-C2UR035

Overview

The ATMXT1664T3-C2UR035 is a maXTouch touchscreen controller manufactured by Microchip Technology. It functions as a 1664-node capacitive touch sensor IC designed for high-channel-count applications. The device supports multiple communication interfaces including I2C, SPI, and USB, allowing flexible integration with host processors. It operates within a supply voltage range of 1.8V to 3.6V and is rated for industrial temperature ranges. This component provides advanced touch processing capabilities for complex user interfaces.

Feature Summary

• Supports up to 1664 touch nodes for large or multi-zone displays
• Integrated self-capacitance and mutual-capacitance sensing
• Multiple interface options: I2C, SPI, and USB
• Configurable via external configuration data stored in host memory

Applications

• Large-format interactive whiteboards
• Industrial control panels with extensive button arrays
• Automotive infotainment systems requiring high node counts
• Medical equipment with complex touch interfaces

Procurement Notes

Verify the specific suffix 'C2UR035' against official Microchip documentation to confirm package type, temperature grade, and tape/reel specifications. Ensure compatibility with existing firmware configurations, as maXTouch devices require precise configuration data matching the hardware revision. Check for end-of-life status or alternative recommendations from the manufacturer before finalizing procurement plans.

Selection Notes

Select this model when the application requires more than 128 channels, necessitating the 1664-node capacity. Confirm that the host system can support the required interface (I2C/SPI/USB) and has sufficient memory to store the configuration file. Verify that the operating environment falls within the specified temperature range and voltage constraints defined in the datasheet.

Part Context

This part belongs to the maXTouch family of touchscreen controllers from Microchip. The T3 designation typically indicates a specific generation or feature set within the 1664-node series. The C2UR035 suffix denotes specific packaging, temperature rating, and shipping format details unique to this ordering code.

Replacement Considerations

Direct replacements must match the 1664-node count and pinout. Consult Microchip's official substitution guide for any updated revisions or equivalent parts with identical electrical characteristics and interface support.
