Who is first invented 8051 microcontroller or 8051 microprocessor?
Intel
What is microcontroller8051?
The 8051 Microcontroller is a microcontroller ("chip") developed by Intel in 1980.
What is microcontroller 8051?
The 8051 is a microcontroller. It has the MCS-51 core by Intel and was designed for embedded systems in the 1980's. The name of the CMOS version is 80C51. Today the core is still used in microcontrollers from other companies like Atmel, e.g. AT89C51.
Is 8051 is Harvard architecture?
The Intel 8051 is a Harvard architecture, single chip microcontroller (µC) which was developed by Intel in 1980 for use in embedded systems. Intel's original versions were popular in the 1980s and early 1990s, but has today largely been superseded by a vast range of faster and/or functionally enhanced 8051-compatible devices manufactured by more than 20 independent manufacturers including Atmel, Infineon Technologies (formerly Siemens AG), Maxim Integrated Products (via its Dallas Semiconductor subsidiary), NXP (formerly Philips Semiconductor), Nuvoton (formerly Winbond), ST Microelectronics, Silicon Laboratories (formerly Cygnal), Texas Instruments and Cypress Semiconductor. Intel's official designation for the 8051 family of µCs is MCS 51.Nandakumar (Source Wikipedia)
What is the purpose of 8051 microcontrollers?
8051 Microcontrollers were popular computer chips used in Intel computers throughout the eighties and nineties. Though technology has advanced beyond their common use, they can still often be found in engineering schools as tools used in introductory microcontroller classes.
Which company introduced the worlds first microprocessors?
intel in 1917, named intel 4004.
What is a 8051 Micro-controller?
An 8051 microcontroller is a popular 8-bit microcontroller that was first introduced by Intel in 1980. It is widely used in embedded systems due to its simple architecture, low cost, and ease of use. The 8051 microcontroller typically includes CPU, RAM, ROM, I/O ports, timers, and serial communication interfaces on a single chip.
Why there is no driver circuit needed between 8051 microcontroller and an optoisolater?
Are you referring to the original Intel 8051, or one of the many variants? The 8051 has weak internal pullups on the i/o pins, and can source only about 60 ua, but can sink 1.6 ma, still not much when it comes to driving the led in an opto. Some 8051-based dervatives can sink much more current. Atmel's 89C2051 for instance, can sink up to 20 ma per i/o pin. This can directly drive most optos.

Differences between Intel 8051 and atmel 89c51 micro controller?
The instructions used by Atmel 89CXX and 89CXXXX are the same or subset of 8051 microcontrollers.Fully static operation,flash program memory,less pin count andprecision analog comparator ( in case of 89C20510)are some of the attractions in going for these microcontrollers. Due to many similar features in the architecture and instruction and instruction set as that of 8051, it becomes possible for the 8051 designer to directly start using 89CXX and 89C20XX microcontrollers without any more efforts in learning these microcontrollers.
What is the use of two capacitor with crystal in 8051?
The "requirement" of using two capacitors with the crystal in the 8051 is complicated, and based on many factors, such as series resistance, the design of the parallel resonant feedback circuit, stray or parasitic capacitance, startup stability, etc. Insight can be gained from Intel's Application Note AP-155 but, in the final analysis, from a purely pragmatic standpoint, the requirement is there simply because "Intel says so". Use the circuit from the data sheet.
Disadvantages of Intel 8051?
disadvantages:1.It has limitations on the size of data. 2.Most Microprocessor does not support floating-point operations. 3.over heating physically, 4. not bit addressable,
