Description (Brief)
Marked on top: “i / D4004 / W1082718 / S1310 BI”; on bottom: “E BJ / Philippines”. The Intel 4004 microprocessor was released on November 15, 1971. Packaged in a 16-pin ceramic dual in-line package is a 4-bit central processing unit (CPU). The 4004 is the first complete CPU on one chip, the first commercially available microprocessor, a feat made possible by the use of the new (1970) silicon gate technology allowing the integration of a higher number of transistors (2,300) and a faster speed than was possible before. The 4004 employed a 10 um silicon-gate enhancement load pMOS technology and could execute approximately 92,000 instructions per second (a single instruction cycle was 11 microseconds).
