ST72F262G1B6集成電路（IC）的微控制器規(guī)格書PDF中文資料

ST72F262G1B6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ST72F262G1B6微控制器微控制器產(chǎn)品是相對復(fù)雜的用戶可編程數(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。不過按照傳統(tǒng)，微控制器集成了工作存儲器，也更可能包含混合信號外設(shè)，并且往往與更簡單的軟件范例結(jié)合使用，旨在重復(fù)執(zhí)行一系列預(yù)定義的任務(wù)。

INTRODUCTION

The ST72260G, ST72262G and ST72264G devices are members of the ST7 microcontroller family. They can be grouped as follows :

– ST72264G devices are designed for mid-range applications with ADC, I2C and SCI interface capabilities.

– ST72262G devices target the same range of applications but without I2C interface or SCI.

– ST72260G devices are for applications that do not need ADC, I2C peripherals or SCI.

All devices are based on a common industrystandard 8-bit core, featuring an enhanced instruction set.
