eZ80L92 Module
This chapter describes the eZ80L92 Module hardware, its interfaces and
key components, including the CPU, Ethernet Media Access Control, and
memory.
Functional Description
The eZ80L92 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 via
Ethernet and/or IrDA. Additional devices such as serial ports, LED
matrices, general-purpose port, and I
2
C devices are supported when
connected to the eZ80Acclaim! ® Development Platform. A block diagram
representing both of the boards is illustrated in Figure 1 on page 4 .
The eZ80L92 Module is developed to be a plug-in module to the
eZ80Acclaim! ® Development Platform. This small-footprint module pro-
vides 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 eZ80
®
product 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.
Physical Dimensions
The dimensions of the eZ80L92 Module PCB is 64 x 64 mm. With an
RJ-45 Ethernet connector, the overall height is 25 mm. See
