Features
PS006614-1208
Zilog’s eZ80190 microprocessor is a high-speed single-cycle instruction-fetch micropro-
cessor with a clock speed of up to 50 MHz. It is the first of a new set of products based
upon Zilog’s eZ80
The eZ80 CPU is one of the fastest 8-bit CPUs available today, executing code up to four
times faster with zero wait-state memory than a standard Z80
quency. 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 eZ80 CPU’s
processing power rivals the performance of 16-bit microprocessors.
