EMC characteristics
Susceptibility tests are performed on a sample basis during product characterization.
7.9.1
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).
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.
FTB: A Burst of Fast Transient voltage (positive and negative) is applied to VDD, VDDQ
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 resumed. The test results are given in the
table below based on the EMS levels and classes defined in application note AN1709.
