The '''Zilog eZ80''' is an [[8-bit computing|8-bit]] microprocessor designed by [[Zilog]] as an updated version of the company's first product, the highly-successful [[Zilog Z80]]. The eZ80 is [[binary compatible]] with the Z80, but it operates almost three times faster at the same [[clock frequency]].
