ATMXT640T-CCU

Overview

The ATMXT640T-CCU is a maXTouch touchscreen controller IC manufactured by Microchip Technology. It supports two-wire capacitive touch input and features I2C and SPI communication interfaces. The device operates within a supply voltage range of 1.71V to 3.47V, with a typical operating current of 40 mA. It is designed for surface-mount installation in an 88-UFBGA package measuring 6x6 mm. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

Supports 2-wire capacitive touch sensing technology
Dual interface capability with I2C and SPI support
Operates on supply voltages between 1.71V and 3.47V
Available in compact 88-UFBGA (6x6) surface-mount package

Applications

Industrial control panels requiring robust touch input
Consumer electronics utilizing capacitive touch interfaces
Embedded systems with I2C or SPI host controllers

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and environmental rating. Ensure compatibility with the target system's voltage levels and communication protocols before procurement. Check for RoHS compliance status relevant to the manufacturing region.

Selection Notes

Select this component when a 2-wire capacitive solution is required with flexible bus connectivity. Confirm that the host processor supports the necessary I2C or SPI speeds. Verify that the PCB layout can accommodate the 88-UFBGA footprint and thermal requirements for the specified operating temperature range.

Part Context

This part belongs to the maXTouch family of touchscreen controllers from Microchip Technology. It serves as a dedicated sensor controller for managing touch inputs in embedded applications.
