1971!it was 4004!
The first Intel 4-bit micrprocessor, and arguably the first ever microprocessor was the the 4004, introduced in 1971.
In November, 1971, a company called Intel publicly introduced the world's first single chip microprocessor, the Intel 4004 (U.S. Patent #3,821,715), invented by Intel engineers Federico Faggin, Ted Hoff, and Stan Mazor.
The Intel 8080 was the first microprocessor using an 8 bit databus.
Ted hughes was the first person who designed microprocessors. In 1971 Ted hughes make first microprocessor for intel. The name of the first microprocessor was: Intel-4004. It contains lacs of electronic circuits.
I assume you mean an Intel Microprocessor. Intel has made many different microprocessors, starting with the 4 bit Intel 4004 in 1971 followed by the 8 bit Intel 8008 in 1972. The modern Intel Microprocessor used in PC is a 32 bit or 64 bit Microprocessor whose architecture is derived from the 8 bit Intel 8008. Some of the other Intel Microprocessor in this path of architectural evolution are the 8 bit Intel 8080, the 8 bit Intel 8085, the 16 bit Intel 8086 (and the 16 bit Intel 8088 with 8 bit external multiplexed databus), the 16 bit Intel 80186, the 16 bit Intel 80286, the 32 bit Intel 80386 (first 80x86 Microprocessor to implement virtual memory), the 32 bit Intel 80489, the 32 bit Intel Pentium (was originally to have been the 80586, but you cannot Trademark numbers only words and Intel wanted a Trademark at that time to protect their IP rights). Intel also built many other Microprocessors with unrelated architectures (e.g. 3000 series bitslice, 80432, 80860, 80960).
Intel had produced four bit and eight bit Microprocessor chips in the 1970's and it started it's 16 bit family of microprocessor chips with the 8086 chip and the family has developed through five generations to date.
8 bit input is given to Intel 8085 microprocessor.
8085 is a 8 bit microprocessor designed by Intel Co.
Intel invented the 32 and 64 bit microprocessor which are in all modern computers
The question is unclear, but it looks like it meant to ask when the first microprocessor was invented. That was the Intel 4004, invented in 1971. It was the first single chip microprocessor, and the first microprocessor available commercially. The 4004 was a 4 bit processor, with a 12 bit address bus and an 8 bit opcode. Everything was multiplexed, 4 bits at a time, in 8 clock cycles per instruction.
b/c the 8085 microprocessor is the first 8 bit microprocessor which Intel is produces in 1877 and this is the first general purpose 8 bit microprocessor. there was an 8 bit general purpose register before 8085 named as 8008 but this microprocessor is not functional 8 bit microprocessor
The Intel 8088 microprocessor was a variant of the Intel 8086 and was introduced on July 1, 1979. It had an 8-bit external data bus instead of the 16-bit bus of the 8086. The 16-bit registers and the one megabyte address range were unchanged, however. The original IBM PC was based on the 8088.
