The eZ80F91 Mini Enet Module
The eZ80F91 Mini Enet Module is a compact, high-performance Ethernet module
specially designed for the rapid development and deployment of embedded sys-
tems requiring control and Internet/Intranet connectivity.
This expandable module is powered by ZiLOG’s latest power-efficient, high-
speed, optimized pipeline architecture eZ80F91 microcontroller, a member of
ZILOG’s family of eZ80Acclaim! Flash Microcontrollers.
The eZ80F91 is a high-speed single-cycle instruction-fetch microcontroller, which
can operate with a clock speed of 50 MHz. It can operate in Z80-compatible
addressing mode (64 KB) or full 24-bit addressing mode (16 MB).
The rich peripheral set of the eZ80F91 Mini Enet Module makes it suitable for a
variety of applications, including industrial control, IrDA connectivity, communica-
tion, security, automation, point-of-sale terminals, and embedded networking
applications.
