PIC12F508集成電路（IC）的微控制器規(guī)格書PDF中文資料

PIC12F508屬于集成電路（IC）的微控制器。由微芯科技股份有限公司制造生產(chǎn)的PIC12F508微控制器微控制器產(chǎn)品是相對復(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。不過按照傳統(tǒng)，微控制器集成了工作存儲器，也更可能包含混合信號外設(shè)，并且往往與更簡單的軟件范例結(jié)合使用，旨在重復(fù)執(zhí)行一系列預(yù)定義的任務(wù)。

GENERAL DESCRIPTION

The PIC12F508/509/16F505 devices from Microchip Technology are low-cost, high-performance, 8-bit, fully-static, Flash-based CMOS microcontrollers. They employ a RISC architecture with only 33 single-word/ single-cycle instructions. All instructions are single cycle (200 μs) except for program branches, which take two cycles. The PIC12F508/509/16F505 devices deliver performance an order of magnitude higher than their competitors in the same price category. The 12-bit wide instructions are highly symmetrical, resulting in a typical 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.
