Zilog Z80 bites the dust

dougw
dougw over 2 years ago

I just noticed this extinction event.

Littelfuse who own the Zilog Z80 IP announced the Z80 would cease production in June 2024.  (Semiconductor fab lines are not interested in running a 4 micron process)

Fortunately the eZ80 system-on-a-chip is still in production if you want to pursue this technology.

At one time I was ultra keen to obtain or build a Z80 microcomputer, but never managed to scrounge enough money until recently when I made a low cost emulator on an ESP32....

    Incidentally there's a book that might be of interest to people.

    I can't say it's written like a bestseller, but the guy isn't a journalist or author, he created the Z80!. So I take back even the slightest criticism in that previous sentence : ) Plus, it's a first-hand account, so that's also a significant positive.

    I bought the book and have read it now. Very interesting stuff about the early development of logic chips. I hadn't realised just how manual the process on the first 8080 and Z80 was.

    The book is somewhat spoiled by the random AI/philosophical stuff, of which there is far too much - you did warn us !

    Just read the excerpt you posted.  I've suffered a bit in PCB layout when it's a challenge to fit everything onto a tiny board... but yeah what Federico went through would have been a hundred times worse.
