The PSoC family consists of many Mixed-Signal Array with OnChip Controller devices. These devices are designed to replace multiple traditional MCU-based components with one, low cost single-chip programmable component. A PSoC device includes configurable analog and digital blocks, as well as programmable interconnect. This architecture allows 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. The architecture for this device family, as illustrated above, is comprised of three main areas: the Core, the CapSense Analog System, and the System Resources (including a full-speed USB port). A common, versatile bus allows connection between IO and the analog system. Each CY8C20x46/CY8C20x66 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 36 general purpose IO (GPIO) are also included. The GPIO provides access to the MCU and analog mux.
