Automotive PSOC™ 4700S Plus

Overview

The PSOC™ 4700S Plus product family is the industry’s first microcontroller with a single chip with inductive and capacitive sensing technology. The inductive sensing technology enables the sensing of metal objects and the industry's leading capacitive sensing (CAPSENSE™) technology enables the sensing of non-metallic objects.

The PSOCTM 4700S Plus family is Automotive Electronics Council (AEC) AEC-Q100 qualified
