Introduced in 1976 as Zilog’s first product, the Z80 was the brainchild of ex-Intel engineer Federico Faggin and Masatoshi Shima. It was designed as an enhanced alternative to Intel’s 8080, optimized for embedded applications, and rapidly became a top choice for microcomputers of the era. Competing closely with MOS Technology’s 6502, the Z80 found its way into numerous iconic systems, such as the Sinclair ZX Spectrum, Tandy TRS-80, and even Namco’s Pac-Man arcade games.
Despite its retro roots, the Z80 still powers some embedded systems and nostalgia-driven projects, offering a gateway to the simpler tech of past decades. Yet, Zilog is now sunsetting the standalone CPU models, marking the end of an era for one of the most widely sourced CPUs in computing history.
A recent product change notice from Zilog’s parent company, Littelfuse, confirmed the end-of-life status of 13 Z80 parts in the Z84C00 family. The last date for orders is set for June 14, 2024, after which these parts will no longer be available. These parts are commonly used for repairing vintage machines or creating new builds inspired by classic systems. Notably, this discontinuation does not impact the eZ80 range, which continues to serve embedded applications.
Additionally, the Z180 core line will also cease production, with the same last-time-buy date. This decision may lead enthusiasts to seek alternatives or stockpile parts for future projects, as a remarkable chapter in the history of microprocessors draws to a close.
