Atmel® maXTouch® touchscreen controllers combine patented Atmel charge transfer technology and either an 8-, 16- or 32-bit Atmel AVR® microcontroller (MCU). These advanced devices provide unlimited touch (up to 16 touches), fast response time and smart processing of a capacitive touch image, which accurately regenerates and reports the user’s interaction with the touchscreen. Multitouch performance identifies and individually tracks touches, while allowing a range of built-in gestures to be reported to the host processor.

A high signal-to-noise ratio (SNR) enables these devices to work well with fingertip touch as well as a conductive stylus. They have also been designed to work in demanding, rapidly changing environments. In addition, since only the touchscreen area is touch-sensitive, you have the freedom to place the chip on the main board or adjacent to the sensor.

Integrated Atmel maXFusion™ Sensor Hub technology fuses sensor data from devices such as accelerometers, gyroscopes and magnetometers to deliver real-time motion sensing information. The result is a visibly superior user experience with gaming, navigation or virtual reality applications. Integrating maXFusion technology with maXTouch devices offers the added benefits of reduced system cost and lower power consumption.
