The Intel 8080 is an eight-bit microprocessor designed and manufactured by Intel in the mid 1970s.[1]
| specification | value |
|---|---|
| number of transistors | 6,000 transistor on die |
| clock speed | 2 megahertz |
| instruction set | 75 instructions |
| Registers | seven eight bit registers.[2] |
| introduction date | January 4, 1974 |
| initial cost | $360 each |
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.[3]
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.[2] The 8080 was the lineal descendant of the Intel 4004 and Intel 8008 microprocessors.[3]
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".[1] The 8052 was embedded in non-computer devices, like microwave ovens, and electronic fuel ignitions.
