Intel 4004 Microprocessor Release

On November 15, 1971, Intel Corporation released the Intel 4004, the world’s first commercial microprocessor, marking a groundbreaking moment in the field of computing and electronics. This event signified a major technological advancement in the development of microprocessors, which would eventually lead to the creation of personal computers and the digital devices we use today.

Background

In the late 1960s and early 1970s, the need for more efficient and compact computing solutions became increasingly apparent, particularly in the electronics industry. Intel, a relatively new company founded in 1968 by Robert Noyce and Gordon Moore, sought to capitalize on this opportunity. The Intel 4004 was developed as part of a contract with Nippon Calculating Machine Corporation to design a set of integrated circuits for their Busicom 141-PF printing calculator.

Development

The Intel 4004 was designed by a team led by engineers Federico Faggin, Ted Hoff, and Stanley Mazor. The microprocessor integrated the functionality of a central processing unit (CPU) onto a single silicon chip, a revolutionary concept at the time. The 4004 consisted of 2,300 transistors, had a processing speed of 740 kHz, and was capable of performing about 92,000 operations per second. It was built using a 10-micron process technology and utilized a 4-bit databus, which allowed for addressing 640 bytes of memory.

Significance

The introduction of the Intel 4004 opened up new possibilities for computing by drastically reducing the size and cost of electronic devices while enhancing their capability. This innovation laid the groundwork for the microprocessors used in modern computers and countless other electronic devices. The 4004 demonstrated the potential of integrating CPUs and marked the beginning of the microprocessor revolution.

Legacy

The release of the Intel 4004 was a pivotal event that spurred rapid advancements in microprocessor technology. It signified the beginning of the era of personal computing and played a crucial role in the development of subsequent generations of microprocessors, such as the Intel 8008 and 8080. Today’s digital landscape owes much to the groundbreaking work done by the team that created the 4004, as it set a precedent for the future of electronic innovation and integration.
