ATMXT1664S-CUR044

Overview

The ATMXT1664S-CUR044 is a maXTouch capacitive touch sensor integrated circuit manufactured by Microchip Technology. It supports up to 1664 reconfigurable touch channels, enabling control of large and complex display surfaces. The device operates within a supply voltage range of 1.8 V to 3.3 V and functions reliably across an industrial temperature range from -40°C to +85°C. It utilizes I2C and USB interfaces for communication and data transfer. The component is housed in a UFBGA-162 surface-mount package, designed for high-density PCB integration in advanced touchscreen applications.

Feature Summary

Supports extensive channel counts for large-format displays
Integrates multiple communication protocols including I2C and USB
Operates within standard industrial temperature limits

Applications

Large-format commercial displays
Industrial human-machine interfaces
Automotive infotainment systems

Procurement Notes

Verify the specific suffix CUR044 against official Microchip documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing firmware configurations before procurement. Check for any product change notifications or lifecycle status updates directly from the manufacturer to avoid obsolescence risks during production planning.

Selection Notes

Select this component when high channel density is required for expansive touch surfaces. Confirm that the host system supports the necessary I2C or USB interface speeds. Evaluate power consumption requirements against the 1.8V to 3.3V operating range. Ensure the PCB layout accommodates the UFBGA-162 package dimensions and thermal dissipation needs.

Part Context

This part belongs to the maXTouch family of touch controllers, which are widely used in consumer electronics and industrial automation. The 1664-channel capacity distinguishes it from lower-density variants, making it suitable for next-generation large-screen devices requiring precise multi-touch input handling and robust gesture recognition capabilities.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Consider the ATMXT1664T series if automotive qualification is not required. Verify pin-to-pin compatibility and firmware support before transitioning to alternative part numbers.
