1D Turnkey Solutions


Turnkey Touch solutions are the speed boats for your touch user interface. With a  fixed functionality and simple GUI based configuration they offer the shortest time-to-market (TTM). From a single button, via sliders and proximity, via water tolerant touch up to 64 buttons – Microchip offers fast and reliable turnkey touch solution. Hook them up to the sensor – power up – done.


1D Touch Library Solutions – Touch on MCU


Every MCU from Microchip with an ADC (PIC, AVR, SAM) can realize touch. To ensure your touch project benefits from proven touch algorithms for highest performance and reliability Microchip offers touch  libraries – These libraries are the essence of several decades of touch expertise, readily available for your design.

maXTouch® Touchscreen Controllers


Turnkey Solution for Multi-Finger Robust and Reliable Touch Pads and Screens


The maXTouch touch controller family provides a leading projected capacitive technology for touchscreens and touch pads. It supports single-finger, multi-fingers and gloved-finger operation. Regardless of the operating environment—hot or cold, dry or wet, noisy power supply or strong radiating surrounding devices—maXTouch controllers are designed for robust and reliable operation without compromising touch performance.


The maXTouch portfolio covers solutions for all touch surfaces and touch screens up to 24” diagonal size. Additionally, I2C, SPI, and USB communication interfaces are available. maXTouch controllers embed best-in-class and proven touch algorithms which ease the touch system development and significantly reduce time to market.


2D Touch Libraries


With maXTouch®, Microchip offers the leading multi touch solution for touch pad and touch screens in automotive and industrial applications.


2D Touch on MCUs is an alternative solution for smaller touch pads and touch screens. Key element is the integration of the user interface into the main controller of your device.  Supported are 8-bit PIC controller and 32-bit SAM controller – Low power and cost efficient platforms.


2D Analog Resistive Touch


The AR11xx series is legacy product suite for analog resistive touch. Cost effective, support for finger, stylus and Pen are just some key advantages of this mature technology.

3D Gestures

GestIC® Technology


The MGC3030 and MGC3130 are the world’s first electrical near–field (E-field) 3D gesture controllers. Based on Microchip’s patented GestIC® technology, they enable user gesture detection and motion tracking. Interaction with devices is as simple and intuitive as a wave of the hand. The MGC controller family enables single-chip gesture solutions, with no host processing needed for embedded applications.


GestIC Technology Benefits:


  • True single-chip gesture solution for embedded usage
  • From 0 (touch) to 20 cm detection range
  • Very low–power design
  • No detection blind spots
  • No ambient influences (light/sound)
  • Usage of thin, low-cost sensing electrodes, e.g. standard PCB
  • Requires no openings in the housing
  • Highest gesture detection reliability
  • Active noise handling
  • 44-115 kHz carrier frequency no RF interference


Typical Applications:


  • Notebooks/PC peripherals (e.g. the 3DTouchPad from Microchip)
  • Audio products
  • White goods/appliances/air conditioning control
  • Home automation
  • Light switches
  • Industrial/medical switches
  • Electronic readers
  • Game controllers
