General Description
The eZ80F92 Ethernet Module is a compact, high-
performance Ethernet module specially designed
for rapid development and deployment of embed-
ded systems requiring control and Internet/Intranet
connectivity.
This low-cost, expandable module is powered by
ZiLOG’s latest power-efficient, optimized pipeline
architecture eZ80F92 microcontroller¹. This device
is part of ZiLOG’s new eZ80Acclaim! product line,
which offers MCUs featuring integrated IrDA capa-
bilities and rich on-chip peripherals.
Combined with a 10Mbps 802.3 Ethernet control-
ler, memories, and ZiLOG’s industry-leading IrDA
transceiver, this module is ideal for wireless IrDA
connectivity, industrial control, communication,
security, automation, and embedded networking
applications.
For rapid development, this module can interface to
the eZ80^® Development Platform, which provides a
1. ZiLOG also offers an eZ80^® Development Module
based on the eZ80F93 MCU, which is intrinsically the
same device, yet offering a smaller memory size.
complete user debug environment with power,
breadboard area, and serial connectors such as RS-
232 and JTAG. For deployment, this compact mod-
ule interfaces to a user system via its system inter-
face connectors. An RJ-45 Ethernet connector is
provided on the module.
System designers with aggressive time-to-market
requirements can take comfort in the fact that this
tested module, together with available ZiLOG TCP/
IP Internet connectivity software and OS, will facil-
itate quick product launch and low ownership cost.
