Industry Standard Moving To Chmos

14 EE INDUSTRY STANDARD MOVING TO CHMOS High CPU power and a very high level of integration have developed the Type 80186 and 80188 16-bit microprocessors into industry standards in the embedded control arena. Most systems in the automation and power engineering area, like CNC machines and robots, are based on the 80186/188 architecture. INTEL"s 80C186 is the newest member of the popular, high integrated 80186/ 188 microprocessor family. The chip provides full hardware and software compatibility with its NMOS prede- cessor 80186 and gives the design engin- eer additional opportunities via an inte- grated DRAM refresh unit, special power-saving logic and the new asyn- chronous numerics coprocessor (NPX) interface. The 80C186 is manufactured with IN- TEL"s CHMOS III process technology (the same process on which the 32-bit 80386 is based) and is specified for 10, 12.5, or 16 MHz operation. Two operating modes The 80C186 supports two operating modes: Compatible Mode and En- hanced Mod...
