The CY8C25122/CY8C26233/CY8C26443/CY8C26643 family of Programmable System-on-
Chip (PSoC™) microcontrollers replaces multiple MCU-based system components with one sin-
gle-chip, programmable device. A PSoC microcontroller includes a fast CPU, Flash program
memory, and SRAM data memory with configurable analog and digital peripheral blocks in a
range of convenient pin-outs and memory sizes. The driving force behind this innovative Pro-
grammable System-on-Chip comes from user configurability of analog and digital arrays: the
PSoC blocks.
