The EMAC can be additionally protected by placing an ESD protection array on
the eZ80L92 Module at position U9. Either use ESDA25B1 from ST Microelec-
tronics or LCDA15C-6 from Semtech. A mounting hole on the board can be used
for grounding the shield of the Ethernet RJ45 jack to prevent surge or ESD cur-
rents from flowing through the digital circuitry.
The RJ45 Ethernet Connector on the eZ80L92 Module contains a transformer and
common mode chokes for EMI suppression.
The components are mounted on a multilayer PCB to provide a stable ground
plane for onboard components. The module features several GND pins next to
pins with higher switching frequency for short ground returns. If unused, the clock
output can be separated from the module header by removing a series resistor on
the module. Removing the series resistor further reduces electromagnetic emis-
sions.
Stresses greater than those listed in Table 5 can cause permanent damage to the
device. These ratings are stress ratings only. Operation of the device at any con-
dition outside those indicated in the operational sections of these specifications is
not implied. Exposure to absolute maximum rating conditions for extended peri-
ods may affect device reliability. For improved reliability, unused inputs should be
tied to one of the supply voltages (V
The eZ80L92 Module is a component that is intended to be part of a
system design for end-user devices. Therefore, the user must exercise
caution to use ESD protection on the I/O pins.
CMOS I/Os are ESD-sensitive and must be handled with care. Han-
dling of the module should be performed in ESD-safe environments (for
example with a wrist-wrap attached). When developing applications,
the user must provide for proper ESD protection on external, user-
accessible I/Os (e.g. suppressor arrays for the I/Os).
