Sensor Controller Capacitive 448-CH I2C/SPI 100-Pin TQFP T/R

The mXT449T-A uses the latest capacitive touch technologies that Microchip has designed for the highest-performance automotive touchscreens in the centerstack or entertainment systems. With a revolutionary adaptive-sensing architecture featuring both mutual- and self-capacitance, it enables the highest performance supporting hover, gloved touch and thick lens support. Hover operation will track the position of the finger when it floats within 20mm of the touchscreen. Hover allows user interaction without making a physical contact, and brings a more dynamic interface to user applications. In addition it provides best in class water and moisture immunity guaranteeing that no false touch will be detected under this harsh conditions. With 448 nodes, the mXT449T-A touchscreen controller supports touchscreens up to 8”.
