ATMXT1664S-CU

Overview

The ATMXT1664S-CU is a maXTouch capacitive touch sensor integrated circuit manufactured by Microchip Technology. It supports up to 1664 channels for high-resolution touch sensing applications. The device operates within a supply voltage range of 1.8V to 3.6V and functions across an industrial temperature range from -40°C to +85°C. It is housed in a VFBGA-128 package, suitable for surface-mount assembly. This component serves as a dedicated controller for complex multi-touch interfaces.

Feature Summary

Supports extensive channel counts for large-area or high-density touch panels
Integrates advanced signal processing for reliable multi-touch detection
Compatible with standard serial communication protocols for host interfacing

Applications

Large-format interactive displays
Industrial control panels requiring robust touch input
Consumer electronics with high-node count touchscreens

Procurement Notes

Verify the specific suffix 'CU' against the latest Microchip datasheet to confirm package type and temperature grade. Check for obsolescence status as this part may be discontinued. Ensure compatibility with existing firmware configurations before procurement.

Selection Notes

Select this model when a high node count exceeding 1000 is required for the touch interface. Compare against the ATMXT1664T series if automotive qualification or different packaging is needed. Confirm that the VFBGA-128 footprint matches the PCB design constraints.

Part Context

This component belongs to the maXTouch family of capacitive touch controllers. It is designed to replace older resistive touch solutions with more responsive and durable capacitive alternatives. The 1664-channel capacity allows for support of very large screens or highly segmented touch areas.

Replacement Considerations

The ATMXT1664T2-C2UR039 is a related variant within the same functional family. Verify pinout and software compatibility before substitution. Other models like ATMXT1664S1 may offer updated features but require firmware adaptation.
