ST7FLITE25F2B6集成電路（IC）的微控制器規(guī)格書(shū)PDF中文資料

ST7FLITE25F2B6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ST7FLITE25F2B6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)。

Description

ST7LITE20F2, ST7LITE25F2 and ST7LITE29F2 are referred to as ST7LITE2. The ST7LITE2 is a member of the ST7 microcontroller family. All ST7 devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set.

The ST7LITE2 features FLASH memory with byte-by-byte In-Circuit Programming (ICP) and In-Application Programming (IAP) capability.
