Intel 4004 Microprocessor was considered to be an innovative computer part November 1971 when it was first brought to the public attention. By that time most of the engineers felt that integrated circuit technology was not quite ready to support such a chip, however Ted Hoff from Intel, had another feeling. He understood the importance of such a piece and that the new silicon-gated MOS technology might make a single-chip CPU possible.
Naming Intel’s early numbering scheme for integrated circuits used a four-digit number for each component. The first digit indicated the process technology used, the second digit indicated the generic function, and the last two digits of the number were used to indicate the sequential number in the development of the component.
- A pioneer – is had the smallest microprocessor design that ever went into commercial production.
- Powerful yet small – delivered the same computing power as the first electronic computer that filled and entire room
- A serious amount of transistors – 2 300 transistors, which was a great number for that period of time
- Very slim – the circuit line width was 10 microns, or 10,000 nanometers
Conclusion: Intel 4004, was the first commercially available microprocessor. Nowadays, the 64-bit microprocessors are still based on similar design, and the microprocessor is still the most complex mass-produced product ever.
