PSoC™ 1 reducing your 8-bit system cost
The PSoC™ architecture for the CY8C20x34 device, 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 CY8C20x34 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 I/O (GPIO) are also included. The GPIO provide access to the MCU and analog mux.
