The First Microprocessor Invention History
In exchange for the product's rights, Intel promised to repay Busicom's $60,000 investment. The Japanese corporation consented despite its financial difficulties. Nobody, even Intel, knew the significance of the acquisition at the time, which laid the road for Intel's future in CPUs.
As a consequence, the 4-bit Intel 4004 CPU was introduced as part of the MCS-4 microcomputer set on November 15, 1971. The 4004 had a maximum clock speed of 740KHz (740,000 cycles per second, or approximately 3/4 of a megahertz); it had 2,300 transistors on a 12 sq. mm (3.5mm3.5mm) area; and it was created using a 10-micron process, with each transistor located around 10 microns apart. The maximum accessible memory was just 640 bytes, and data was sent 4 bits at a time. The chip cost around $200 and had almost the same processing capability as the ENIAC, one of the earliest electronic computers. When ENIAC was completed in 1946, it used 18,000 vacuum tubes crammed into a space of 3,000 cubic feet (85 cubic meters).
