Introduction
Unless specifically noted, all references to the Intel® 80C186EA apply to the Intel® 80C188EA, Intel® 80L186EA, and Intel® 80L188EA. References to pins that differ between the Intel® 80C186EA/80L186EA and the Intel® 80C188EA/ 80L188EA are given in parentheses. The “L” in the part number denotes low voltage operation. Physically and functionally, the “C” and “L” devices are identical.
The 80C186EA is the second product in a new generation of low-power, high-integration microprocessors. It enhances the existing Intel® 80C186XL family by offering new features and operating modes. The 80C186EA is object code compatible with the 80C186XL embedded processor.
