to prevent unrecoverable errors occurring. See application note Software techniques for

improving microcontrollers EMC performance (AN1015) for more details.

Electromagnetic Interference (EMI)

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

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

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

5.3.12

Electrical sensitivity characteristics

Based on three different tests (ESD, latch-up) 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

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

conforms to the ANSI/JEDEC standard.
