This ready-to-use, low-power, and water-resistant touch device is part of Microchip's unified ecosystem, which simplifies the design process and transitions between other ready-to-use and microcontroller-based touch solutions. The MTCH2120 is the first model in a new family of I2C-based touch controllers with a comprehensive design-oriented system.
The MTCH2120 provides a robust touch experience, independent of noise and humidity, and offers high flexibility to adapt to the requirements of each product. Its low power consumption allows buttons to be grouped, reducing scanning activity and energy consumption while keeping the buttons fully functional.
These are the main features of the MTCH2120 and its ecosystem:
• Easy Tune function that automatically adjusts filter sensitivity and levels based on real-time noise, eliminating the need for cumbersome threshold level adjustments.
• An MPLAB® Harmony Host Code Configurator extension that eliminates the need to implement the I2C protocol on the host and simplifies connectivity with Microchip microcontrollers and microprocessors.
• Design validation via MPLAB Data Visualizer
. • I2C port expandability.
• Access to and compatibility with the Microchip Touch Library, minimizing the need for complex software and firmware engineering, thus helping to reduce design cycles.
• The MTCH2120 evaluation board, which incorporates a SAM C21 host microcontroller for direct integration into prototypes.
“The MTCH2120 combines decades of experience in touch technology and Microchip’s comprehensive ecosystem with development tools and support to deliver an advanced, user-friendly touch experience,” said Rodger Richey, vice president of development systems and academic programs at Microchip Technology. “It’s a winning solution. Developers can implement the highest level of touch robustness and excellent design flexibility without the hassle of tuning or programming.”.
The MTCH2120 is the first in Microchip's MTCH family to incorporate I2C, while the recently introduced MTCH1010, MTCH1030, and MTCH1060 offer the same robust touch performance with a simple GPIO interface. The MTCH2XXX family will be expanded with more bus-controlled solutions, bringing the ease of use provided by the design-oriented ecosystem to other markets.
