Absolute maximum ratings (electrical sensitivity)

Based on three different tests (ESD, LU) using specific measurement methods, the device is

stressed in order to determine its performance in terms of electrical sensitivity.

Electrostatic discharge (ESD)

Electrostatic discharges (a positive then a negative pulse separated by 1 second) are

applied to the pins of each sample according to each pin combination. The sample size is

either 3 parts (cumulative mode) or 3 parts × (n + 1) supply pins (non-cumulative mode).

The human body model (HBM) can be simulated. The tests are compliant with JESD22-

A114A standard.

For more details, refer to the application note AN1181.

Static latch-up

Two complementary static tests are required on six parts to assess the latch-up

performance:

●

A supply overvoltage is applied to each power supply pin

●

A current injection is applied to each input, output and configurable I/O pin

These tests are compliant with EIA/JESD 78A IC latch-up standard.
