EMC characteristics

5.4.1

Electrostatic discharge (ESD)

Electrostatic discharges (3 positive then 3 negative pulses separated by 1 second) are

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

depends on the number of supply pins in the device (3 parts * (n + 1) supply pin).

Data based on characterization results, not tested in production.

5.4.2

Static latch-up

Two complementary static tests are required on 10 parts to assess the latch-up

performance.

A supply overvoltage (applied to each power supply pin) and a current injection (applied to

THE each input, output and configurable I/O pin) are performed on each sample. This test

conforms to the EIA/JESD 78 IC latch-up standard.
