The Intel 4004, released by the Intel Corporation in 1971, was the first commercially produced microprocessor and the first in a long line of Intel central processing units (CPUs). Priced at US$ 60 (equivalent to $466 in 2024), it marked a breakthrough in computing by condensing an entire 4-bit CPU onto a single chip.

Intel 4004是英特尔制造的一款微处理器，片内集成了2250个晶体管，晶体管之间的距离是10微米，能够处理4bit的数据，每秒运算6万次，频率为108KHZ，前端总线为0.74MHz（4bit）。

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 。

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.

【新智元导读】今年是英特尔首款商用微处理器4004诞生50周年。4004为10微米工艺，仅有2250个晶体管，但却开启了计算和芯片产业的伟大时代，彻底改变了人类的生活。这个故事，要从1969年的一款计算器讲起。 今年是英特尔首款商用芯片4004诞生50周年。

The Intel® 4004 is a complete 4-bit parallel central processing unit (CPU). The 4004 easily interfaces with keyboards, switches, displays, A-D converters, printers and other peripheral equipment. The CPU can directly address 4K 8-bit instruction words of program memory and 5120 bits of data storage RAM. Sixteen

The 4004 was the first single chip microprocessor, originally designed and manufactured by Intel for Busicom for use in their calculators. It was invented by Intel engineers Federico Faggin, Ted Hoff, and Stan Mazor and introduced in November 1971.

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 …

The birth of the 4004 was an intense moment witnessed by Faggin alone, working into the night in the deserted Intel labs. He had received the 4004 wafers from the manufacturing line at around 6 PM, in January 1971, as people were leaving for the day. With hands trembling and heart pounding he loaded the wafers in the wafer prober and connected ...
