PSoC™ Automotive Multitouch Gen7XL

概要

Infineon designed the new PSoC™ Automotive & Transportation Multitouch Gen7XL 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.
