to prevent unrecoverable errors occurring (see application note AN1015, available on

www.st.com).

Electromagnetic interference (EMI)

The electromagnetic field emitted by the device are monitored while a simple application is

executed (toggling two LEDs through the I/O ports). This emission test is compliant with the

IEC 61967-2 standard, which specifies the test board and the pin loading.

Electrical sensitivity characteristics

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

stressed 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

depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test

conforms to the ANSI/JEDEC standard.

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.
