SB80C186EB20

IC MPU 16Bit 5V 20MHz 80-SQFP

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.
