The MTCH2120 touch controller is designed for seamless integration with a comprehensive tool ecosystem, simplifying development processes and accelerating time-to-market. This turnkey solution offers a straightforward way to upgrade mechanical buttons to modern touch buttons or displays.
Microchip Technology Inc.'s MTCH2120 provides a direct approach for implementing touch button functionality in user interfaces. As a low-power, water-resistant device, it integrates into Microchip's unified ecosystem, streamlining design processes and facilitating transitions between turnkey and MCU-based touch implementations. It is the first product in a series of I2C-based touch controllers supporting a full design ecosystem.
The MTCH2120 ensures a reliable touch experience unaffected by noise or humidity while offering flexibility to meet diverse product requirements. Its low-power design minimizes scanning activity by grouping buttons, reducing energy consumption without compromising performance.
Key features and ecosystem integrations include:
- Easy Tune Functionality: Automatically adjusts sensitivity and filter levels based on real-time noise assessments, eliminating manual threshold adjustments.
- MPLAB® Harmony Host Code Configurator Plugin: Simplifies integration by removing the need for implementing I2C protocols on the host.
- Design Validation via MPLAB Data Visualization Tools: Enables efficient prototyping and evaluation.
- I2C Port Expander Capabilities: Enhances interface flexibility.
- Access to Microchip’s Touch Library: Reduces the need for complex software engineering, accelerating the design cycle.
- MTCH2120 Evaluation Board: Comes with an onboard SAM C21 MCU, ready for immediate integration into prototypes.
Rodger Richey, VP of Microchip’s Development Systems and University Programs, highlighted the controller's advanced touch capabilities and ease of use, offering robust performance and design adaptability without requiring extensive programming or manual adjustments.
The MTCH2120 is part of Microchip's MTCH series, which includes other high-performance models such as the MTCH1010, MTCH1030, and MTCH1060. Future MTCH2XXX series products will introduce enhanced bus control flexibility, expanding the ecosystem's usability across various markets.
