General description

PSoC™ 4 is a scalable and reconfigurable platform architecture for a family of programmable embedded system

controllers with an Arm® Cortex®-M0+ CPU. It combines programmable and reconfigurable analog and digital

blocks with flexible automatic routing. The PSoC™ 4000S product family is a 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, programmable general-purpose

continuous-time and switched-capacitor analog blocks, and programmable connectivity. PSoC™ 4000S products

are upward compatible with members of the PSoC™ 4 platform for new applications and design needs.
