The Intel 4004 is an early single chip computer chip, from 1971, and a lineal ancestor of the Pentium family of computer chips.[1][2]
| specification | value |
|---|---|
| number of transistors | 2,300 transistor on die[1][2] |
| clock speed | 108 hertz[2], 740 hertz[1] |
| bus speed | 108 hertz[2] |
| instruction set | 46 instructions[1] |
| Registers | 16 4 bit registers or eight bit registers.[1] |
| introduction date | November 1971[2] |
| memory | 1k data memory, 4k program memory[1] |
| address space | 4k[1] |
| transistor size | 10 micron[2] |
The computer had separate data and memory spaces. The maximum addressable memory was 4 kilobytes.[1]
According to the History of Computing website the chip "it is widely considered to be the world's first commercial single-chip microprocessor."[1]
