SPEAR300集成電路（IC）的微處理器規(guī)格書PDF中文資料

SPEAR300屬于集成電路（IC）的微處理器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的SPEAR300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。
