4004

The first microprocessor from Intel. Designed by Marcian E. "Ted" Hoff at Intel in 1971, it was a 4-bit, general-purpose CPU initially developed for the Japanese Busicom calculator. Running at a clock rate of 740 kHz, the 4004 could address 4KB of ROM for a program and 640 bytes of RAM for input/output.

A Small But Great Start
Given the tiny amount of RAM the 4004 supported, it was limited to calculator-like applications. Nevertheless, it was the beginning of a long line of microprocessors. The 4040 successor added interrupts, 24 index registers (up from 16) and a second 4KB program bank.

Truckstop's

In November, 1971, Intel, a small start-up company, announced the first microprocessor--the Intel 4004. It used solid state integrated circuit technology that the firm had been using to make memory "chips" to develop the logic circuitry of a computer's central processing unit.
