The PSoCfamily consists of many Programmable System-on-Chips 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 I/O are included in a range of convenient pin outs.The PSoC architecture for this device family consists of three main areas: the Core, the System Resources, and the CapSense Analog System. A common versatile bus enables connection between I/O and the analog system. Each CY8C2 PSoC device includes a dedicated CapSense block that provides sensing and scanning control circuitry for capacitive sensing applications. Depending on the PSoC package, up to 28 general purpose IO (GPIO) are also included. The GPIO provide access to the MCU and analog mux.
