Microchip Introduces its First Turnkey Touch Controllers for Buttons, Sliders and Wheels with Parallel Sensing

  • Microchip Technology launched the MTCH3380P & MTCH3240P turnkey capacitive-touch controllers to enable display-free HMIs with lower system costs & reduced design complexity.
  • These devices utilize parallel sensing with 12 on-chip analog-to-digital converters to support high sensor counts while maintaining fast response times & a high signal-to-noise ratio.
  • The MTCH3380P supports up to 38 sensors in self-capacitance mode or 64 in mutual-capacitance mode, while the MTCH3240P supports up to 24 & 32 sensors respectively.
  • Both controllers offer enhanced touch sensitivity for operation through thick cover materials & with gloves, making them suitable for appliances, outdoor EV chargers, & industrial environments.
  • The new devices support operation up to 105°C & are designed for IEC/UL 60730 Class B functional safety certification.
  • Pricing starts at $1.06 for the MTCH3380P & $0.80 for the MTCH3240P in 10,000-unit quantities.
  • Development support includes mTouch Studio, evaluation hardware, & host drivers for Linux® & Zephyr®.
