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.

A device reset allows normal operations to be resumed.

The test results are given in Table 41. They are based on the EMS levels and classes

defined in application note AN1709.

VPP

Cumulative time during

which VPP is applied

hour

Guaranteed by design, not tested in production.

The maximum programming time is measured after 100K erase operations.

VPP should only be connected during programming/erasing.
