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, 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 PSoC architecture for this device family, as illustrated on the left, is comprised of three main areas the Core, the System Resources, and the CapSense Analog System. A common, versatile bus allows connection between IO 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 IO GPIO are also included. The GPIO provide access to the MCU and analog mux. CY8C20234, CY8C20334, CY8C20434 Final Data Sheet Overview The PSoC Core The PSoC Core is a powerful engine that supports a rich instruction set. It encompasses SRAM for data storage, an interrupt controller, sleep and watchdog timers, and IMO internal main oscillator and ILO internal low speed oscillator . The CPU core, called the M8C, is a powerful processor with speeds up to 12 MHz. The M8C is a two-MIPS, 8-bit Harvard architecture microprocessor. System Resources provide additional capability, such as a configurable I2C slave/SPI master-slave communication interface and various system resets supported by the M8C. The Analog System is composed of the CapSense PSoC block and an internal 1.8V analog reference, which together support capacitive sensing of up to 28 inputs. The CapSense Analog System The Analog System contains the capacitive sensing hardware. Several hardware algorithms are supported. This hardware performs capacitive sensing and scanning without requiring external components. Capacitive sensing is configurable on each GPIO pin. Scanning of enabled CapSense pins can be completed quickly and easily across multiple ports.
