MCS-51 - Wikipedia
ウェブThe Intel MCS-51 (commonly termed 8051) is a single chip microcontroller (MCU) series developed by Intel in 1980 for use in embedded systems. The architect of the Intel MCS-51 instruction set was John H. Wharton. [1] [2] Intel's original versions were popular in the 1980s and early 1990s, and enhanced binary compatible derivatives ...

ウェブIntel 8051 は 1980年 、 組み込みシステム 用に インテル が開発した ハーバード・アーキテクチャ をもつワンチップ マイクロコントローラ である。 1980年代から1990年代初頭まで極めて広範に用いられたが、2006年現在では様々な機能拡張を施された8051互換のプロセッサコアが20以上の製造業者から出荷されている。 例えば Atmel 、 Maxim …
ウェブAll four ports in the 8051 core are bidirectional. Each port has SFR (Special Function Registers P0 through P3) which works like a latch, an output driver and an input buffer. Both the output driver and the input buffer of Port 0, and the output driver of Ports 2 are used for accessing the external memory.
Introduction to 8051 Microcontroller - GeeksforGeeks
ウェブ2023年4月25日 · 8051 is one of the first and most popular microcontrollers also known as MCS-51. Intel introduced it in the year 1981. Initially, it came out as an N-type metal-oxide-semiconductor (NMOS) based microcontroller, but later versions
Explore Intel’s history- The 8051 Microcontroller
ウェブThe 8051 family could accommodate programs up to 16 times larger than Intel's previous flagship controller, the 8048. Its capabilities would allow it to find a home in everything from anti-lock brakes and airplanes to musical
8051 Datasheet(PDF) - Intel Corporation
ウェブ8051 Product details. The MCS@51 controllers are optimized for control applications. Byte-processing and numerical operations on small data structures are facilitated by a variety of fast addressing modes for accessing the internal RAM. The instruction set provides a convenient menu of 8-bit arithmetic instructions, including multiply and ...
ウェブThe following set of 8051 microcontroller features are available in Core8051s, but are either optional or reduced in scope: • Multiply and divide instructions (MUL, DIV, and DA) – present by default, but may optionally be • Of the ...
A History of Early Microcontrollers, Part 8: The Intel 8051
ウェブ2022年12月19日 · by Steven Leibson. Intel introduced the successor to its 8048 microcontroller, the 8051, in 1980. It’s become the immortal microcontroller, and it was all because an applications engineer forgot to bring his wallet to work one day and asked his boss at Intel to buy lunch. Intel announced the 8048 microcontroller in 1976.
ウェブThe original Intel 8051 core took 12 cycles to execute 1 instruction; thus, at 12 MHz, it ran at 1million instructions per second (1 MIP). In contrast, a 100 MHz Silicon Labs 8051 core will run at 100 MIPS or 100 times faster than the classic 8051 at a frequency that is only about 8x the classic 8051’s frequency.
