eZ80

eZ80

An 8-bit microprocessor from Zilog that was four times as fast as the Z80. Introduced in 2000, the eZ80 was suited for Internet appliances, PDAs and games and could address up to 16MB of RAM. As of 2019, eZ80 CPUs were still being offered in Zilog microcontrollers. See Z80 and microcontroller.

The new eZ80 Internet Engine is a synthesizable core that retains compatibility with the original, and according to Zilog offers "a clear migration path" for existing Z80 customers.
The eZ80 essentially combines microprocessor and DSP digital signal processing capabilities onto a single chip, also embedding an optimized TCP/IP stack and linear addressing that supports up to 16Mb of addressing space.
Because it's a synthesizable core, the eZ80 should be easily portable to any process geometry, from .5 to .18 micron and beyond.
