ST72F623F2M1集成電路（IC）的微控制器規(guī)格書(shū)PDF中文資料

ST72F623F2M1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ST72F623F2M1微控制器微控制器產(chǎn)品是相對(duì)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(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)。

INTRODUCTION

The ST7262 and ST72F62 devices are members of the ST7 microcontroller family designed for USB applications.

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

The ST7262 devices are ROM versions.

The ST72F62 versions feature dual-voltage FLASH memory with FLASH Programming capability.

Under software control, all devices can be placed in WAIT, SLOW, or HALT mode, reducing power consumption when the application is in idle or standby state.

The enhanced instruction set and addressing modes of the ST7 offer both power and flexibility to software developers, enabling the design of highly efficient and compact application code. In addition to standard 8-bit data management, all ST7 microcontrollers feature true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes.
