PSOC 1 Family CY8C21x23 Series Microcontrollers 8-bit Microcontrollers:

The PSoC architecture consists of four main areas: the Core, the System Resources, the Digital System and the Analog System. Each CY8C21x23 device includes four digital blocks. Depending on the PSoC package, up to two analog comparators and up to 16 general purpose IOs (GPIO) are also included. The GPIO provides access to the global digital and analog interconnects.
