New Family of maXTouch Touchscreen Controllers Designed for Large Screen

A family of maXTouch touchscreen controllers is now available from Microchip Technology Inc. The MXT1665T-A family of automotive qualified touchscreen controllers is designed for large screen automotive human machine interface (HMI) designs. The technology brings the user experience of multi-touch HMI, such as on a mobile phone, to car drivers and passengers in screen sizes from eight to 15 inches.

MXT1665T-A family carries Microchip’s adaptive touch technology that utilizes self-capacitive touch as well as mutual capacitive touch scanning. This combination provides the multi-touch experience even with thick cover lenses, thick gloves or in the presence of moisture and water. The product family is fully AEC Q100 qualified to address all the unique needs of automotive system designs.

The family complements the MXT641T-A family of products. It shares many of the same features developed for the automotive industry, but is able to address larger screen sizes over 10 inches. The MXT1665T-A family supports screen sizes from eight to 15 inches and also supports smaller multi-finger pinch separation.

By having a large range of screen size options within Microchip’s touchscreen controller families, companies are more scalable. It will ultimately shorten design time, and lower system and development cost.

The MXT1665T-A family consists of three parts that are all available now, the MXT1665T-A supports 1664 touch node sensors, the MXT1189-A supports 1188 touch node sensors and the MXT799T-A with 798 touch node sensors.

A designated evaluation kit is available for each of the parts in the MXT1665T-A family. The kit includes a PCB with maXTouch controller, a touch sensor on a glass/plastic lens, the FPC to connect to the sensor display, a converter PCB to connect this kit to the host PC via USB, as well as cables, software and documentation. All parts are also compatible with maXTouch Studio, a full software development environment to support the evaluation of maXTouch.
