Module Block Diagram
General Description
The eZ80L92 Module is a compact, high- perfor-
mance Ethernet module specially designed for rapid
development and deployment of embedded systems
requiring control and Internet/Intranet connectivity.
This low-cost, expandable module is powered by
ZiLOG’s latest power-efficient, optimized pipeline
architecture eZ80L92 microprocessor with inte-
grated IrDA capabilities and rich on-chip peripher-
als.
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
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.

TCP/IP Software
ZiLOG’s royalty-free TCP/IP Internet software
suite is an integrated, preemptive multitasking OS
and TCP/IP protocol stack that meets all of the rele-
vant RFCs. It is optimized for embedded systems
and is implemented as an extension to the ZiLOG
C-Compiler’s runtime library. Supported protocols
and network features are:
TCP, UDP, IP, ARP, RARP, ICMP, IGMP, PPP
FTP, SMTP, HTTP, TELNET, DNS
TFTP, SNMP, DHCP/BOOTP, TIMEP
In-system configuration or updates of network
parameters, web pages, and module firmware
A set of well-documented OS and network service
APIs allow system developers to quickly take
advantage of the ZiLOG TCP/IP software suite
while remaining focused on the main application.
Final binary output from the compiler/linker is the
complete user application with networking capabil-
ities across the Internet or any Intranet.
