12.7 EMC CHARACTERISTICS
Susceptibility tests are performed on a sample ba-
sis during product characterization.
12.7.1 Functional EMS
(Electro Magnetic Susceptibility)
Based on a simple running application on the
product (toggling 2 LEDs through I/O ports), the
product is stressed by two electro magnetic events
until a failure occurs (indicated by the LEDs).
s
ESD: Electro-Static Discharge (positive and
negative) is applied on all pins of the device until
a functional disturbance occurs. This test
conforms with the IEC 1000-4-2 standard.
s
FTB: A Burst of Fast Transient voltage (positive
and negative) is applied to VDD and VSS through
a 100pF capacitor, until a functional disturbance
occurs. This test conforms with the IEC 1000-4-
4 standard.
A device reset allows normal operations to be re-
sumed.

Notes:
1. Data based on characterization results, not tested in production.
2. The suggested 10nF and 0.1
F decoupling capacitors on the power supply lines are proposed as a good price vs. EMC
performance tradeoff. They have to be put as close as possible to the device power supply pins. Other EMC recommen-
dations are given in other sections (I/Os, RESET, OSCx pin characteristics).
