PSoC Functional Overview

The PSoC® family consists of many Mixed Signal Arrays with On-Chip Controller devices. These devices are designed to replace multiple traditional MCU based system components with one low cost single chip programmable component. A PSoC device includes configurable analog and digital blocks and programmable interconnect. This architecture enables the user to create customized peripheral configurations to match the requirements of each individual application. Additionally, a fast CPU, Flash program memory, SRAM data memory, and configurable IO are included in a range of convenient pinouts.
