INTRODUCTION
Unless specifically noted, all references to the 80C186EB apply to the 80C188EB, 80L186EB, and 80L188EB. References to pins that differ between the 80C186EB/80L186EB and the 80C188EB/80L188EB 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 80C186EB is the first product in a new generation of low-power, high-integration microprocessors. It enhances the existing 186 family by offering new features and new operating modes. The 80C186EB is object code compatible with the 80C186XL/80C188XL microprocessors.
