The Intel 4004 - The Original Microprocessor

The Intel 4004 was the first CPU on a single chip as well as the first available to the commercial market. This week it celebrated it’s 40th birthday! We would like to say thank you to the microprocessor that grandfathered the CPUs we have today. A CPU is the brain of a computer. Known as the central processing unit, every piece of information in or out of a computer goes though the CPU. Just imagine what the Intel 4004, a tiny yet powerful CPU, did for the computing world in 1971. CPUs have come a considerable ways since then, but they continue to be a huge part of our everyday lives.

The Intel 4004 was originally created for a calculator, but it quickly led to technological leaps in computing. Many common products would not exist if it weren’t for the powerful CPUs born from the Intel 4004. These products include laptops, streetlights, and cell phones. The Intel 4004 quite literally grandfathered many modern technologies. Check out this article showing the evolution of technology thanks to the CPU.

We can’t say happy birthday to the Intel 4004 without mentioning the engineers responsible for its development. Federico Faggin led the planning and development of the Intel 4004 with Ted Hoff, and Stan Mazor. In this ever-changing world of technology we can lose sight of its humble origins. The Intel 4004 was no small player in this.

So take the time to appreciate the little microprocessor that grandfathered the technological world of today.
