Automotive PSOC™ 4000 - Infineon Technologies

Overview

The PSOC™ 4000 product family is the smallest member of the PSOC™ 4 platform architecture. It is a combination of a microcontroller with standard communication and timing peripherals, a capacitive touch-sensing system (CapSense®) with best-in-class performance, and general-purpose analog.

The automotive PSOC™ 4000 products will be fully upward compatible with members of the PSOC™ 4 platform for new applications and design needs.
