PSoC™ 1 reducing your 8-BIT system cost
The PSoC™ family consists of many Mixed Signal Array with On-Chip Controller devices. These devices are designed to replace multiple traditional MCU-based system components with a low cost single-chip programmable component. A PSoC™ device includes configurable blocks of analog and digital logic, and 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, consists of four main areas: the Core, the System Resources, the Digital System, and the Analog System. Configurable global bus resources allow the combining of all device resources into a complete custom system. Each CY8C21x23 device includes four digital blocks. Depending on the PSoC™ package, up to two analog comparators and up to 16 general purpose IO (GPIO) are also included. The GPIO provide access to the global digital and analog interconnects.
