Although the demise of the Zilog Z80 processor has long been predicted, it would seem that this moment has finally arrived. The owner of the Zilog name – Littelfuse – recently sent out PCN ZAC26-0074, notifying customers that they will be taking final orders for the eZ80 and all other microcontroller lines that they currently own.
Over at Mouser, eZ80 parts have correspondingly all been marked as “End of Life”. This comes a few years after the original Z80 and its peripherals were discontinued, with the eZ80 still being an alternative until now.
Any potential sellers will have to put in their orders today, with orders still accepted until December 21 2026, with final deliveries taking place throughout 2027 as Littelfuse winds down its MCU manufacturing. This means that for commercial customers are least this is pretty much the end of the road for any circuit that still uses the eZ80 or similar.
Many of us have fondness for the Z80, which also has led to a potential way that the Z80 can live on. This includes both the many open source cores that are compatible with the Z80, as well as real silicon courtesy of the TinyTapeout project.
