Intel 8080

The Intel 8080 is an eight-bit microprocessor designed and manufactured by Intel in the mid 1970s.

Like rival microprocessors like the Motorola 6800, the Intel 8080 used registers that were only eight bits wide.

Zilog later produced a object compatible replacement, the Zilog Z80|Z80, with some extended features.

The Altair (microcomputer)|Altair, Imsai and Tandy Radio Shack TRS80 microcomputer was built around the intel 8080.

The 8080 is the lineal ancestor of intel's later designs, the intel 8088|8088, intel 8086|8086, intel 80186|186, intel 80286|286, intel 80386|386, intel 80486|486 and all of intel's Pentium processors. The 8080 was the lineal descendant of the Intel 4004 and Intel 8008 microprocessors.

Later integrated circuits intended for embedded computer applications, like the Intel 8052, incorporated the intel 8080 architecture, memory, and what had previously been various support chips on a single chip, allowing a "computer on a chip". The 8052 was embedded in non-computer devices, like microwave ovens, and electronic fuel ignitions.
