Product Summary

The N80C188-20 is a CMOS high-intergration 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 N80C188-20 is 100% pin-for-pin compatible with the NMOS 80186/80188. The enhanced mode of operation allows the full feature set of the 80C186/C188 to be used. The N80C188-20 is upward compatible with 8086 and 8088 software anf fully compatible with 80186 and 80188.
