Architectural Overview
PS006613-0306
Features
The eZ80190 microprocessor is a high-speed single-cycle instruction-fetch micro-
processor with a clock speed of up to 50 MHz. It is the first of a new set of products
based upon the eZ80
The eZ80
up to four times faster with zero wait-state memory than a standard Z80 operating
at the same frequency. This increased processing efficiency can be used to
improve available bandwidth or to decrease power consumption.
Considering both the high clock speed and instruction pipeline efficiency, the
