eZ80190 Module
This section describes the eZ80190 Module hardware, its interfaces and
key components, including the CPU, Ethernet Media Access Controller
(EMAC), and memory.
Functional Description
The eZ80190 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 fast Multiply-Accumulate operations. Additional devices
such as serial ports, LED matrices, GPIO ports, and I
2 C devices are sup-
ported when connected to the eZ80Acclaim! ® Development Platform. A
block diagram representing both of these boards is shown in Figure 1 on
page 4.
The eZ80190 Module is developed to be a plug-in module to the eZ80 ®
Development Platform. The small-footprint eZ80190 Module provides a
CPU, SRAM, Flash memory, a real-time clock, and an EMAC. This low-
cost, expandable module is powered by the eZ80190 microprocessor, a
member of ZILOG’s new eZ80
® product family. The module also con-
tains a battery and an oscillator in support of the onboard Real-Time
Clock (RTC). The eZ80190 Module can also be used as a stand-alone
development tool when provided with an external power source.
Physical Dimensions
The footprint of the eZ80190 Module PCB is 63.5 mm x 78.7 mm. With an
RJ-45 Ethernet connector, the overall height is 25 mm. See Figure 11.
