ST7FLITE25F2B6集成电路（IC）的微控制器规格书PDF中文资料

ST7FLITE25F2B6属于集成电路（IC）的微控制器。由意法半导体集团制造生产的ST7FLITE25F2B6微控制器微控制器产品是相对复杂的用户可编程数字逻辑器件。这些产品与视为微控制器的器件密切相关，两者之间的区别主要体现在制造商选择的用词。不过按照传统，微控制器集成了工作存储器，也更可能包含混合信号外设，并且往往与更简单的软件范例结合使用，旨在重复执行一系列预定义的任务。

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.
