RCA 1802 - Moore's Law In Pictures

Before we leave 8-bit computing behind, let’s take a moment to remember the RCA 1802, which NASA put on board the Galileo probe to Jupiter in 1989. The microprocessor was created much earlier than that, of course. It was ideal for a mission like this because of its static CMOS design, which had no minimum clock frequency--it could run at very low speeds and very low power. Galileo often used little power for much of its six year journey. The chip could also be manufactured using a process called Silicon on Sapphire, which was ideally suited for the radiation and electrostatic shock of outer space.
