MTCH6102T-I/SS

Overview

The MTCH6102T-I/SS is a low-power projected capacitive touch controller manufactured by Microchip Technology. It supports up to 15 sensor channels for gesture detection including taps, swipes, and scrolling. The device operates on a 1.8V to 3.6V supply with an active current consumption of less than 12 µA and standby current below 500 nA. It features an I²C interface supporting speeds up to 400 kbps and provides 12-bit resolution coordinate reporting at frame rates exceeding 200 reports per second. The component is housed in a 28-pin SSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports up to 15 RX channels for XY touch pads and screens
• I²C interface with configurable sleep/idle frame rates
• Detects gestures including taps, swipes, and double-taps
• 12-bit resolution coordinate reporting with >200 Hz frame rate

Applications

• Wearable devices such as watches and fitness wristbands
• Track pads and computer peripherals
• Gaming devices and remote control touch pads
• Home automation control panels and security keypads

Procurement Notes

Verify the ordering suffix 'T' indicates tape and reel packaging configuration compared to standard tube packaging. Confirm the '-I' suffix denotes the industrial temperature grade range of -40°C to +85°C. Ensure the '/SS' designation matches the required 28-SSOP surface mount package type for the specific PCB layout constraints.

Selection Notes

Select this controller for applications requiring single-finger gesture support with minimal power consumption. The device accommodates cover layers up to 3 mm plastic or 5 mm glass. Designers must ensure the sensor layout utilizes contiguous channels starting from RX0 without gaps in the middle of the axis configuration.

Part Context

The MTCH6102 is part of Microchip's turnkey projected capacitive touch controller family. It simplifies integration into cost-sensitive designs by providing built-in filtering and gesture decoding algorithms. The device allows field upgrades over the I²C interface and supports various sensor materials including PCB, film, glass, and flexible printed circuits.
