ST72T141K2B6集成電路（IC）的微控制器規(guī)格書(shū)PDF中文資料

ST72T141K2B6屬于集成電路（IC）的微控制器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的ST72T141K2B6微控制器微控制器產(chǎn)品是相對(duì)復(fù)雜的用戶(hù)可編程數(shù)字邏輯器件。這些產(chǎn)品與視為微控制器的器件密切相關(guān)，兩者之間的區(qū)別主要體現(xiàn)在制造商選擇的用詞。不過(guò)按照傳統(tǒng)，微控制器集成了工作存儲(chǔ)器，也更可能包含混合信號(hào)外設(shè)，并且往往與更簡(jiǎn)單的軟件范例結(jié)合使用，旨在重復(fù)執(zhí)行一系列預(yù)定義的任務(wù)。

GENERAL DESCRIPTION

INTRODUCTION

The ST72141K devices are members of the ST7 microcontroller family designed specifically for motor control applications and including A/D conversion and SPI interface capabilities. They include an on-chip Moter Controller peripheral for control of electric brushless moters with or without sensors. An example application, for 6-step control of a Permanent Magnet DC motor, is shown in Figure 1.
