The Intel M80C186 is a CHMOS high integration microprocessor It has features which are new to the M80186
family which include a DRAM refresh control unit power-save mode and a direct numerics interface When
used in ‘‘compatible’’ mode the M80C186 is 100% pin-for-pin compatible with the NMOS M80186 (except for
M8087 applications) The ‘‘enhanced’’ mode of operation allows the full feature set of the M80C186 to be
used The M80C186 is upward compatible with M8086 and M8088 software and fully compatible with M80186
and M80188 software
