Automotive touchscreen controllers aim for large-screen HMI designs

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

The chips are available for a wide range of screen size options and support larger screen sizes above 10 inches in addition to smaller multi-finger pinch separation. The MXT1665T-A family consists of three controllers: the MXT1665T-A supports 1664 touch-node sensors; the MXT1189-A supports 1188 touch-node sensors; and the MXT799T-A with support for 798 touch-node sensors.

All are available now for sampling and volume production in a LQFP176 package. A designated evaluation kit is available for each of these parts.
