CY8C25122, CY8C26233, CY8C26443, CY8C26643 Device Data Sheet for Silicon Revision D 8-Bit Programmable System-on-Chip (PSo C™) Microcontrollers CYPRESS MICROSYSTEMS September 5, 2002 Document #: 38-12010 CY Rev. - - CMS Rev. 3.20 Cypress Micro Systems CY8C25122/CY8C26233/CY8C26443/CY8C26643 Family Data Sheet CYPRESS MICROSYSTEMS The CY8C25122/CY8C26233/CY8C26443/CY8C26643 family of Programmable System-on Chip (PSo C™) microcontrollers replaces multiple MCU-based system ponents with one single-chip, programmable device. A PSo C 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 Programmable System-on-Chip es from user configurability of analog and digital arrays: the PSo C blocks.
