Description

N80C188-25 Rochester Electronics 1 Core, 16-Bit Microprocessor 25MHz 5.0V DRAM 68-LCC. The 80C186/80C188 is a CMOS high-integration microprocessor. It has features that are new to the 80186/80188 family, which include a DRAM refresh control unit, and power-save mode. When used in “compatible” mode, the 80C186/80C188 is 100% pin-for-pin compatible with the NMOS 80186/80188 (except for 8087 applications). The Enhanced mode of operation allows the full feature set of the 80C186/80C188 to be used. The 80C186/80C188 is upward compatible with 8086 and 8088 software and fully compatible with 80186 and 80188 software.
