eZ80F91 Mini Enet Module
Zilog’s eZ80F91 Mini Enet Module is a compact, high-performance Ethernet module
specially designed for the rapid development and deployment of embedded systems
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 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.
