The Intel 4004 is a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. Sold for US$60 (equivalent to $450 in 2023 [ 2 ] ), it was the first commercially produced microprocessor , [ 3 ] and the first in a long line of Intel CPUs .

Intel 4040 DIP chip pinout. The 4040 was essentially an expansion of the 4004, with additional pins, more registers and new instructions to take advantage of both. The 4004 had a single ROM pin, whereas the 4040 added another ROM pin to allow two banks of ROM. This effectively increased the ROM address from 12 to 13 bits, or 8 kB.
The first commercial microprocessor was the binary-coded decimal (BCD-based) Intel 4004, [2] [3] developed for calculator applications in 1971; it had a 4-bit word length, but had 8-bit instructions and 12-bit addresses. It was succeeded by the Intel 4040, which added interrupt support and a variety of other new features.
Intel introduced its first PMOS microprocessor, the Intel 4004, in 1971. A number of companies followed Intel's lead. Most early microprocessors were manufactured in PMOS technology: 4040 and 8008 from Intel; IMP-16, PACE and SC/MP from National Semiconductor; TMS1000 from Texas Instruments; PPS-4 [13] and PPS-8 [14] from Rockwell International.
The 4004 was designed for Busicom, which had earlier proposed a multi-chip design in 1969, before Faggin's team at Intel changed it into a new single-chip design. The 4-bit Intel 4004 was soon followed by the 8-bit Intel 8008 in 1972.
Intel Haswell Core i7-4771 CPU, sitting atop its original packaging that contains an OEM fan-cooled heatsink. This generational list of Intel processors attempts to present all of Intel's processors from the 4-bit 4004 (1971) to the present high-end offerings.
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
