eZ80F91 Mini Enet Module for
eZ80AcclaimPlus!^™
Zilog’s eZ80F91 Mini Enet Module for eZ80AcclaimPlus!™ family is a compact, high-
performance Ethernet module specially designed for the rapid development and deploy-
ment of embedded systems requiring remote control and Internet/Intranet connectivity.
This expandable module is powered by the eZ80F91–Zilog’s latest Ethernet controller,
featuring a power-efficient, high-speed, optimized pipeline architecture. This Application
Specific Standard Product (ASSP) is a member of Zilog’s new eZ80AcclaimPlus! family
products.
The eZ80F91 is a high-speed plus single-cycle instruction-fetch device, 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, communication, security,
automation, point-of-sale terminals, and embedded networking applications.
