PIC16C505-04/SL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的PIC16C505-04/SL微控制器微控制器產品是相對復雜的用戶可編程數字邏輯器件。這些產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合使用，旨在重復執(zhí)行一系列預定義的任務。

GENERAL DESCRIPTION

The PIC16C505 from Microchip Technology is a low cost, high-performance, 8-bit, fully static, EPROM/ROM-based CMOS microcontroller. It employs 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 PIC16C505 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 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.
