Z80181集成電路（IC）的微處理器規(guī)格書(shū)PDF中文資料

Z80181屬于集成電路（IC）的微處理器。由Zilog, Inc.制造生產(chǎn)的Z80181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(shù)語(yǔ)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(huì)在設(shè)備內(nèi)集成工作存儲(chǔ)器，不太可能集成混合信號(hào)外設(shè)，并且可能在更為復(fù)雜的軟件范式下使用，這些范式涉及使用操作系統(tǒng)來(lái)管理多任務(wù)同時(shí)執(zhí)行。

GENERAL DESCRIPTION

The Z80181 SAC? Smart Access Controller (hereinafter, referred to as Z181 SAC) is a sophisticated 8-bit CMOS microprocessor that combines a Z180-compatible MPU (Z181 MPU), one channel of Z85C30 Serial Communication Controller (SCC), a Z80 CTC, two 8-bit general-purpose parallel ports, and two chip select signals, into a single 100-pin Quad Flat Pack (QFP) package (Figures 1 and 2). Created using Zilogs patented Superintegration? methodology of combining proprietary IC cores and cells, this high-end intelligent peripheral controller is well-suited for a broad range of intelligent communication control applications such as terminals, printers, modems, and slave communication processors for 8-, 16- and 32- bit MPU based systems.
