Ken Shirriff has a great write-up on everything from the history to the design configuration of the legendary Intel 8008 microprocessor, which celebrates its 45th anniversary next month.
Intel’s groundbreaking 8008 microprocessor was first produced 45 years ago.1 This chip, Intel’s first 8-bit microprocessor, is the ancestor of the x86 processor family that you may be using right now. I couldn’t find good die photos of the 8008, so I opened one up and took some detailed photographs. These new die photos are in this article, along with a discussion of the 8008’s internal design.
The photo above shows the tiny silicon die inside the 8008 package. (Click the image for a higher resolution photo.) You can barely see the wires and transistors that make up the chip. The squares around the outside are the 18 pads that are connected to the external pins by tiny bond wires. You can see the text “8008” on the right edge of the chip and “© Intel 1971” on the lower edge. The initials HF appear on the top right for Hal Feeney, who did the chip’s logic design and physical layout. (Other key designers of the 8008 were Ted Hoff, Stan Mazor, and Federico Faggin.)
