Microchip expands capacitive touch controller family

11/12/2024 34

Microchip’s MTCH2120 is the first in a family of I2C-based capacitive touch controllers with a comprehensive design-in ecosystem.

Microchip Technology Inc. has launched the MTCH2120 capacitive touch controller, the first in the family of I²C-based touch controllers with a comprehensive design-in ecosystem. The 12-button turnkey touch controller enables easy implementation of touch-button capabilities on user interfaces.

Providing a fast upgrade path from mechanical buttons to modern touch buttons or displays, the low-power, water-tolerant turnkey touch device is integrated with Microchip’s unified ecosystem, and facilitates transitions between other turnkey solutions and microcontroller (MCU)-based touch implementations.

The MTCH2120 provides a robust touch experience independent of noise events and moisture, Microchip said. Low-power features allow buttons to be grouped, reducing scan activity and power, while enabling the buttons to remain fully operational. Other features include I²C port expander capabilities and easy tuning to automatically adjust sensitivity and filter levels based on real-time noise assessment, eliminating the need for threshold tuning.

Ecosystem tools include the MPLAB Harmony Host Code Configurator plug-in that eliminates the need to implement the I²C protocol on the host for a more straightforward connection to Microchip MCUs and microprocessors. It also features design validation via MPLAB Data Visualizer and provides access to Microchip’s touch library, reducing the need for complex software engineering and firmware.

The MTCH2XXX family will add more solutions with bus-controlled flexibility for additional market applications. A MTCH2120 evaluation board includes a SAM C21 host MCU on board for out-of-the box integration into prototypes.
