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 V_DD and
V_SS through a 100 pF capacitor, until a functional disturbance occurs. This test is
compliant with the IEC 61000-4-4 standard.
A device reset allows normal operations to be resumed.
The test results are given in Table 40. They are based on the EMS levels and classes
defined in application note AN1709.
