Preliminary Information
Rev. A1, 04-May-00
49 (60)
The following guide will help to reduce EME:
D Keep the length of PCB current switching signal
tracks to a minimum..
D Adopt a PCB star power routing system connected at
one point.
D Many of the microcontroller port outputs can be con-
figured with several drive strengths. This means that
a high drive output will switch a signal faster than for
example standard drive output. The resulting change
in current in the signal and power lines will also in-
crease, causing an increase in EME. So wherever
speed and drive current is not necessary the ports
should be configured with the lowest drive possible.
D If possible, write the application program to avoid
multiple outputs switching at any instant.
D Cables can be equipped with ferrite rings to slow cur-
rent spikes or the system can be encased in a grounded
conducting casing.

Stresses
greater than those listed under absolute
maximum ratings may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at any condition above those
indicated in the operational section of these specification
is not implied. Exposure to absolute maximum rating
condition for an extended period may affect device
reliability. All inputs and outputs are protected against
high electrostatic voltages (4kV, HBM) or electric fields.
However, precautions to minimize the build-up of
electrostatic charges during handling are recommended.
Reliability of operation is enhanced if unused inputs are
connected to an appropriate logic voltage level (e.g.
VDD).
