The Intel 8080 was the first popular 8-bit microprocessor [[CPU]].  It was the successor to the 8008, which was the very first 8-bit microprocessor.  It was succeeded by the 8085, and then by 16-bit processors.  The [[Zilog Z-80]] had the 8080 instruction set as a subset of its own instruction set.
