Cypress MicroSystems CY8C25122/CY8C26233/CY8C26443/CY8C26643 Family Data Sheet

CYPRESS MICROSYSTEMS

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.
