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 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. PSoC 4000 products will be fully upward compatible with members of the PSoC 4 platform for new applica-
tions and design needs.
