The standard arrangement for a 4004 system is anything up to 16 × 4001 ROM chips (in a single bank) and 16 × 4002 RAM chips (in four banks of four), which together provide the 4 KB program storage, 1024 + 256 nibbles of data/status storage, plus 64 output and 64 input/output external data/control lines (which can themselves be used to operate ...

Intel designed a set of four chips known as the MCS-4. It included a central processing unit (CPU) chip—the 4004—as well as a supporting read-only memory (ROM) chip for the custom applications programs, a random-access memory (RAM) chip for processing data, and a shift-register chip for the input/output (I/O) port.

Intel 4004處理器. 4004是美國 英特爾公司 (Intel) 推出的第1款商用微處理器，也是全球第一款商用微處理器；1971年11月15日发布。 4004處理器的尺寸為3mm×4mm，外層有16隻針腳，內有2,300個晶體管，採用五层設計、10微米製程。

2021年11月15日 · A 4-bit binary logic chip, the 4004 was designed as an alternative to a series of more specific chips that used a decimal architecture by a team that included Busicom's Masatoshi Shima, and...

Is the Intel 4004 really the world's first microprocessor? Yes and no, but mostly yes. The Intel 4004 is widely considered to be the world's first general-purpose CPU-on-a-chip. But there were pioneers of LSI technology at other companies who also deserve credit for their work.

Intel announced the availability of a new product that would change the world: the 4004 general-purpose programmable microprocessor. Instead of having all of its functions built into expensive custom-designed hardware, the 4004 could be mass-produced and then programmed to perform different functions via its software.

Intel's engineers proposed a new design of just four chips, including one that could be programmed for use. That programmable chip, later known as the Intel 4004, became the first general-purpose microprocessor.

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, the world's first microprocessor, is signed with the initials F.F., for Federico Faggin, its designer. Signing the chip was a spontaneous gesture of proud authorship. It was also an original idea, imitated after him by others. Faggin initially etched the F.F. inside the design.

The Intel 4004 (i4004), a 4-bit CPU, was the first microprocessor on a single chip, as well as the first commercially available. At about the same time, some other integrated circuit CPU designs, such as the 1970s military F14 CADC, were implemented as …
