Keywords: Capacitive Touch

Atmel maXTouch touchscreen controllers combine Atmel's patented Charge Transfer and either 8/16-bit or 32-bit Atmel AVR® microcontroller technology to provide unlimited touch (up to 16 touches), fast response time, and smart processing of a capacitive touch image, accurately regenerating and reporting the user's interaction with the touchscreen. Multitouch performance identifies and individually tracks touches, and allows a range of built-in gestures to be reported to the host processor.

A high signal-to-noise ratio (SNR) enables the device to work well with fingertip touch as well as with a conductive stylus. It has been designed to work in demanding, rapidly changing environments, and with only the touchscreen area being touch-sensitive allows design freedom to place the chip on the main board or adjacent to the sensor. Only the touchscreen area is touch-sensitive, allowing designers the freedom to place the chip on the main board or adjacent to the sensor.

The advanced mXT616 and mXT1386 devices offer a high-performance architecture with a fast response time of >150Hz. They support grip suppression and palm rejection, giving users a more intuitive user experience.

  • The mXT224 is a 224-node, single-chip, highly configurable controller suitable for mobile-phone-size touch screens up to 10.2 inches.
  • The mXT616 is a 616-node, 3-chip, 32-bit controller suitable for tablet PCs, mobile Internet devices, smartbooks, and PCs with touchscreens up to 10.1-inches.
  • The mXT1386 is a 1386-node, 4-chip, 32-bit controller suitable for tablet PCs, mobile Internet devices, smartbooks, and PCs with touchscreens up to 15.6-inches.
