PIC16LF84A-04/SO集成电路（IC）的微控制器规格书PDF中文资料

PIC16LF84A-04/SO属于集成电路（IC）的微控制器。由微芯科技股份有限公司制造生产的PIC16LF84A-04/SO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。

DEVICE OVERVIEW

This document contains device specific information for the operation of the PIC16F84A device. Additional information may be found in the PICmicro™ Mid Range Reference Manual, (DS33023), which may be downloaded from the Microchip website. The Refer ence Manual should be considered a complementary document to this data sheet, and is highly recom mended reading for a better understanding of the device architecture and operation of the peripheral modules.
