EMC characteristics

Susceptibility tests are performed on a sample basis during device characterization.

Functional EMS (electromagnetic susceptibility)

While a simple application is executed on the device (toggling 2 LEDs through I/O ports).

the device is stressed by two electromagnetic events until a failure occurs. The failure is

indicated by the LEDs:

•

Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until

a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard.

•

FTB: A burst of fast transient voltage (positive and negative) is applied to VDD and VSS

through a 100 pF capacitor, until a functional disturbance occurs. This test is compliant

with the IEC 61000-4-4 standard.
