The 180-mil-square [0.18 inches-square (4.6 mm-square)] chip contains the logic for a four function 12-digit calculator - more than 2,100 transistors in 360 gates plus 160 flip-flops. Its promise of lower labor costs means a giant step toward a calculator for the consumer market. ... ...
4003, 10-bit shift register. 4004, 4-bit central processing unit (CPU) (the microprocessor) with a maximum clock speed of 750 kHz. Complete 4004 chip-sets were sent to Busicom early in 1971 and by March Shima had built a working 141-PF calculator.
Intel 4004 CPU and associated chips on the circuit board from a Busicom calculator. The result of the discussions between Intel and Busicom was an architecture that reduced the 7-chip Busicom design to a 4-chip Intel proposal composed of CPU, ROM, RAM and I/O (input-output) devices.

In 1969, a Japanese calculator manufacturer called Busicom hired Intel to create chips for a calculator that Busicom designed. Intel devised a chipset (called the MCS-4---short for "Micro Computer System") composed of four integrated circuits (ICs) that dramatically simplified the calculator's internal design. In delivering its solution, Intel deve...
Some controversy existsover which chip was actually the first microprocessor, so historians generally add qualifying statements such as "single chip" and "commercial" to place a narrow focus on each company's achievement. At the time of the Intel 4004's commercial debut in mid-1971, a multi-chip microprocessor was already flying in the US Navy's F-...
Microprocessor technology has dramatically changed since 1971, when Intel's 4004 CPU ran at a mere 740 KHz and contained only 2,250 transistors using a 10 micrometer process. To show just how dramatically things have changed, we've compared the 4004 with Intel's latest top-of-the-line desktop CPU, the recently-announced Intel Core i9-12900K. Here's...
Due to its limited capabilities---and quickly getting eclipsed by more powerful chips such as the Intel 8008---the 4004 didn't see widespread use relative to the 8-bit Intel chips that followed. Still, here's a list of some products that incorporated a 4004 CPU. I've pulled many of these examples from a piece about the 4004I wrote for Technologizer...
Only five months after Intel announced the 4004 in Electronic News, the firm shipped the Intel 8008, the first 8-bit microprocessor. The 8008 launched an era of at-home hobby computers like the Mark-8, whose appearance on the cover of Radio-Electronics in 1974 spurred the personal computer industry. After the 8008, Intel followed up with the 8-bit ...
Nov 16, 2008 · Intel's solution was the world's first single chip microprocessor -- the tiny Intel 4004 -- which powered the Busicom machine to groundbreaking success in 1971. 37 years later, Bill Kotaska has crafted a replica of this historical machine capable of running the software from the original Busicom ROMs.
Nov 15, 2021 · Intel engineer Federico Faggin was on the team that designed the Intel 4004 microprocessor, which made its debut in November 1971. Masatoshi Shima was an engineer with Nippon Calculating Machine Corp., the Japanese firm that designed the Busicom 141-PF printing calculator.
