On last 15th of November 2011, Intel celebrates 40 years of digital revolution. On the same date, 40 years ago is the actual date where by the first Microprocessor was ever built, the Intel 4004.
Intel 4004 is a set of four chips that was called the MCS-4. It included a central processing unit (CPU) chip, the 4004, 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.
Microprocessors are the “brains” inside computers, servers, phones, cars, cameras, refrigerators, radios, TVs and many other everyday devices. The proliferation of microprocessors is due in large part to Intel’s relentless pursuit of Moore’s Law, a forecast for the pace of silicon technology development that states that roughly every 2 years transistor density of semiconductors will double, while increasing functionality and performance and decreasing costs. It has become the basic business model for the semiconductor industry for more than 40 years. – Patrick Darling
Here are some fun facts about the world first Microprocessor:
- Powerful and Small – This revolutionary microprocessor, the size of a little fingernail, delivered the same computing power as the first electronic computer built in 1946, which filled an entire room.
- Manufacturing – The first Intel 4004 microprocessor was produced on two-inch wafers compared to the 12-inch wafers commonly used for today’s products. The Intel 4004 microprocessor is unique in that it is one of the smallest microprocessor designs that ever went into commercial production.
- A Human Hair – The Intel 4004 microprocessor circuit line width was 10 microns, or 10,000 nanometers. Today Intel’s microprocessors have circuit features of 45 or 32 nanometers. By comparison, an average human hair is 100,000 nanometers wide.
