PIC16F57集成电路（IC）的微控制器规格书PDF中文资料

PIC16F57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PIC16F57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。

GENERAL DESCRIPTION

The PIC16F5X from Microchip Technology is a family of low-cost, high-performance, 8-bit, fully static, Flash-based CMOS microcontrollers. It employs a RISC architecture with only 33 single-word/single-cycle instructions. All instructions are single cycle except for program branches which take two cycles. The PIC16F5X delivers performance an order of magnitude higher than its competitors in the same price category. The 12-bit wide instructions are highly symmetrical resulting in 2:1 code compression over other 8-bit microcontrollers in its class. The easy-to-use and easy to-remember instruction set reduces development time significantly.
