Littelfuse Discontinues eZ80 Microcontrollers, Final Orders Due December 21, 2026
Littelfuse's PCN ZAC26-0074 sets final orders for the eZ80 and other MCU lines at December 21, 2026, with deliveries running through 2027.
Littelfuse has notified customers that it is discontinuing the eZ80 and its other microcontroller lines, according to Hackaday. The company issued product change notice PCN ZAC26-0074 setting a final order date for the affected parts.
Orders are being accepted until December 21, 2026. Final deliveries will take place throughout 2027 as Littelfuse winds down MCU manufacturing.
Distributor Mouser has already marked all eZ80 parts as End of Life, giving buyers an early signal that supply is closing out.
The eZ80 is the latest casualty of a gradual retreat from the Zilog architecture. The original Z80 and its peripherals were discontinued a few years before this notice, with the eZ80 positioned as an alternative for designers who wanted to stay on the instruction set.
For those still building on the architecture, open source cores compatible with the Z80 and real silicon from the TinyTapeout project offer a way for it to live on.
