The Zilog eZ80 is an 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 instruction set, but it operates almost three times faster at the same clock frequency. eZ80 features an optional mode that expands memory addressing to 16 megabytes.
