Electrical characteristics

13.8.2

EMI (electromagnetic interference)

Based on a simple application running on the product (toggling two LEDs through the I/O

ports), the product is monitored in terms of emission. This emission test is in line with the

norm SAE J 1752/3 which specifies the board and the loading of each pin.

13.8.3

Absolute maximum ratings (electrical sensitivity)

Based on two different tests (ESD and LU) using specific measurement methods, the

product 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 pin). Two models

can be simulated: Human Body model and Machine model. This test conforms to the

JESD22-A114A/A115A standard. For more details, refer to the application note AN1181.

Static latch-up (LU)

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 the EIA/JESD 78 IC latch-up standard.
