ATMXT1188S-CU

Overview

The ATMXT1188S-CU is a capacitive touch sensor integrated circuit from Microchip Technology, belonging to the maXTouch family. It functions as a touchscreen sensor IC designed for high-channel-count applications. The component supports up to 1188 channels, enabling complex touch interfaces. It operates within a supply voltage range of 1.8 V to 3.3 V and withstands ambient temperatures from -40°C to +105°C. The device utilizes an I2C interface for communication and is housed in a VFBGA-96 package suitable for surface mount technology.

Feature Summary

• Supports high-density touch sensing with up to 1188 channels
• Operates across extended industrial temperature ranges
• Compatible with standard I2C communication protocols

Applications

• Large format capacitive touch displays
• Industrial control panels requiring high channel counts
• Automotive infotainment systems

Procurement Notes

Verify current availability status as this component may be subject to limited supply conditions. Confirm that the specific ordering suffix matches the required package and temperature grade. Check for any product change notifications or end-of-life notices before finalizing procurement plans.

Selection Notes

Select this part when a high number of touch nodes is required within a single controller. Ensure the host system supports the necessary I2C interface speeds. Verify that the VFBGA-96 footprint aligns with the PCB layout constraints and thermal management requirements.

Part Context

This component is part of Microchip's maXTouch series, which provides scalable solutions for touch sensing. It shares architectural similarities with other models like the ATMXT768E-CU but offers significantly higher channel capacity. The series is designed for robust performance in demanding environments.

Replacement Considerations

Direct substitutes are not explicitly listed in available documentation. Consider evaluating other maXTouch variants based on channel count requirements and interface compatibility.
