Zilog on.

While it may surprise some of you not only do Zilog still exists but they still make the Z80 as well as a host of other chips variously based on it. I recently pulled to buts a broken soldering iron only to find a Zilog microcontroller in there. Likely your TV has one. I put tother a few symbols for KiCad for the Z80, Z180, Z380, eZ80 and a few others and stored them as Z80-CPU-for-KiCADon GitHub.
I've done some Z8 but the collection of them is massive so it will be a long time before they are done. If at all, some of the ones I have done are below.


  • Z80
  • Z180 
  • Z280
  • Z380
  • eZ80
  • Z8
  • CIO
  • KIO
  • DART
  • SIO
  • Z16c32
  • Z16c35
  • Z53c80
  • Z8536
  • Z8l382
  • Z85c30
  • Z08530
  • Z08536
  • Z16c30
  • Z80230
  • Z80380

The Z380, an 8-bit chip with 4 gigabytes of memory space, is the best.

L2R Z8, Z80, Z180, Z380 & eZ80
That 16g was an unthinkably large amount of memory about 16,000 times bigger than you average PC at the time(1994), now a single SRAM chip does it all for £110.
