ESD/EMI Protection
Caution: The eZ80190 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.
The EMAC can be additionally protected by placing an ESD protection array on
the eZ80190 at position U9. Either use ESDA25B1 from ST Microelectronics 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 currents
from flowing through the digital circuitry.
The RJ45 Ethernet Connector on the eZ80190 contains a transformer and com-
mon mode chokes for EMI suppression.
Caution: CMOS I/Os are ESD-sensitive and must be handled with care.
Handling of the module should be performed in ESD-safe
environments (for example with a wrist-wrap attached). When
