Electromagnetic Interference (EMI)
Based on a simple application running on the product (toggling 2 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.

1. Data based on characterization results, not tested in production.
2. Refer to application note AN1709 for data on other package types.
Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, and LU) using specific measurement methods, the
product is stressed in order to determine its performance in terms of electrical sensitivity.
For more details, refer to the application note AN1181.
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). This test
conforms to the JESD22-A114A/A115A standard.

Static latchup (LU)
3 complementary static tests are required on 10 parts to assess the latchup performance. A
supply overvoltage (applied to each power supply pin) and a current injection (applied to
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. For more details, refer to the application
note AN1181.
