Microchip's 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.
The 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 very successful 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.
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 supports 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 a maXTouch touchscreen 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 touchscreen controllers.
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.
