SB80L186EC13集成電路（IC）的微處理器規(guī)格書PDF中文資料

SB80L186EC13屬于集成電路（IC）的微處理器。由英特爾制造生產(chǎn)的SB80L186EC13微處理器微處理器產(chǎn)品是用于信息和數(shù)據(jù)處理的集成電路。與主要按照制造商所選術語而視為微控制器的類似產(chǎn)品相比，這些器件有所不同。但是按照傳統(tǒng)，微處理器不會在設備內(nèi)集成工作存儲器，不太可能集成混合信號外設，并且可能在更為復雜的軟件范式下使用，這些范式涉及使用操作系統(tǒng)來管理多任務同時執(zhí)行。

INTRODUCTION

Unless specifically noted, all references to the 80C186EC apply to the 80C188EC, 80L186EC, and 80L188EC. References to pins that differ between the 80C186EC/80L186EC and the 80C188EC/80L188EC are given in parentheses. The ‘‘L’’ in the part number denotes low voltage operation. Physically and functionally, the ‘‘C’’ and ‘‘L’’ devices are identical.
