PSoC® Functional Overview

The PSoC family consists of many Programmable System-on-Chip with on-chip controller devices. These devices are designed to replace multiple traditional microcontroller unit (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 I/O are included in a range of convenient pinouts.
