Functional Description
This section describes the eZ80L92 Module hardware, its interfaces and
key components, including the CPU, Ethernet Media Access Control, and
memory.
The eZ80L92 Module is a compact, high-performance Ethernet module
specially designed for the rapid development and deployment of embed-
ded systems requiring control and Internet/Intranet connectivity via
Ethernet and/or IrDA. Additional devices such as serial ports, LED matri-
ces, general-purpose port, and I

to the eZ80 Development Platform. A block diagram representing both
of these boards is shown in
The eZ80L92 Module is developed to be a plug-in module to the
Development Platform. This small-footprint module provides a CPU,
RAM, Flash memory, an IrDA transceiver, and an Ethernet Media Access
Controller (EMAC). This low-cost, expandable module is powered by the
eZ80L92 microprocessor, a member of ZILOG's new eZ80
family. The module also contains a battery and an oscillator in support of
the on-chip Real-Time Clock (RTC). The eZ80L92 Module can also be
used as a stand-alone development tool when provided with an external
power source.
The dimensions of the eZ80L92 Module PCB is 64x64mm. With an RJ-
45 Ethernet connector, the overall height is 25mm. See Figure 11.
