Cypress designed the new TrueTouch CYAT817 touchscreen controller family specifically to meet rigorous automotive quality standards, while enabling innovative driver and passenger usage models. The family offers class-leading Hover and Force Touch features while meeting stringent automotive electromagnetic interference (EMI) and electromagnetic compatibility (EMC) requirements. For infotainment systems, the CTAT817X can replace mechanical on/off buttons with a capacitive touchscreen, enabling sleek, modern interior designs. The controllers perform acoustic and haptic feedback processing on-chip for faster response times compared to distributed implementations where the chip is connected to a head-unit via a Controller Area Network (CAN) or Low-Voltage Differential Signaling (LVDS) backchannel.
