The PSoC family consists of many devices with on-chip controllers. 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 blocks of analog and digital logic, and programmable interconnect. This architecture makes it possible for you 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. The PSoC architecture, as illustrated in the “Logic Block Diagram” on page 1, comprises of four main areas: the core, the system resources, the digital system, and the analog system. Configurable global bus resources allow all the device resources to be combined into a complete custom system. Each CY8C21x12 device includes one limited digital block and one CapSense block. Depending on the PSoC package, up to 24 GPIOs are also included. The GPIOs provide access to the global digital and analog interconnects.
