The PSoC® family consists of many Mixed Signal Array with On-Chip Controller devices. 这些器件旨在使用一个低成本的单芯片可编程元件取代多个基于 MCU 的传统系统元件。PSoC 器件包含多个可配置的模拟模块、数字模块以及内部互连。这种架构使得用户能够根据每个应用的要求，来创建定制的外设配置。此外，在一系列方便易用的引脚布局和封装中还包含快速 CPU、Flash 程序存储器、SRAM 数据存储器和可配置的 I/O。
Each CY8C20XX6A/S 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 GPIO are also included. The GPIO provides access to the MCU and analog mux.
CY8C20xx6A/S family is low power, at 1.8V and supports USB interface. This family is geared towards battery-powered applications such as Handheld Devices, Mobile, Bluetooth Headsets and towards wall-plugged applications sensitive to electrical noise such as Printers, LCD TVs and Monitors. The 20xx6A family is enabled with SmartSense automatic tuning technology that makes CapSense designs easier than ever to use.
