Who Discovered 8051 microcontroller?
John H. Wharton
The Intel MCS-51 (commonly termed 8051, typically pronounced eight-oh-five-one) 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.
When was the 8051 microcontroller introduced?
1981
8051 is one of the first most popular microcontroller also known as MCS-51. It was introduced by Intel in the year 1981.
How many microcontrollers are there in 8051?
Brief History of 8051 In 1981, Intel introduced an 8-bit microcontroller called the 8051. It was referred as system on a chip because it had 128 bytes of RAM, 4K byte of on-chip ROM, two timers, one serial port, and 4 ports (8-bit wide), all on a single chip.

Home Applications (TVs, VCR, Video Games, Camcorder, Music Instruments, Home Security Systems, Garage Door Openers, etc.) Communication Systems (Mobile Phones, Intercoms, Answering Machines, Paging Devices, etc.) Office (Fax Machines, Printers, Copiers, Laser Printers, etc.)
Who discovered microcontroller first?
One book credits TI engineers Gary Boone and Michael Cochran with the successful creation of the first microcontroller in 1971. The result of their work was the TMS 1000, which became commercially available in 1974.
When was microcontroller invented?
1971
A microcontroller was developed in 1971 by Intel Corporation in the United States. That is the 4 bit microcontroller called i4004. It was ordered by a Japanese company BUSICOM for calculators.
What is the difference between 8051 microcontroller and PIC microcontroller?
PIC stands for Peripheral Interface Controller. PIC micro-controller was developed by Microchip….Difference between 8051 and PIC :
| S.No. | 8051 | PIC |

What is the history of 80C51 microcontroller?
It was introduced by Intel in the year 1981. Initially it came out as N-type metal-oxide-semiconductor (NMOS) based microcontroller, but later versions were based on complementary metal-oxide-semiconductor (CMOS) technology. These microcontrollers were named as 80C51, where C in the name tells that it is based on CMOS technology.
