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, while being AEC-Q100-compliant. 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 applications and design needs.
