描述 Description

The high performance of the PIC16F62X family can beattributed to a number of architectural featurescommonly found in RISC microprocessors. To beginwith, the PIC16F62X uses a Harvard architecture, inwhich, program and data are accessed from separatememories using separate buses. This improvesbandwidth over traditional Von Neumann architecturewhere program and data are fetched from the samememory. Separating program and data memory furtherallows instructions to be sized differently than 8-bitwide data word. Instruction opcodes are 14-bits widemaking it possible to have all single-word instructions.

簡介

PIC16F627屬于集成電路（IC）的微控制器。由制造生產(chǎn)的PIC16F627微控制器微控制器產(chǎn)品是相對復雜的用戶可編程數(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，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，并且往往與更簡單的軟件范例結(jié)合使用，旨在重復執(zhí)行一系列預定義的任務。
