Electrical characteristics

202/243
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.
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). Two models
can be simulated: Human Body Model and Machine Model. This test conforms to the
JESD22-A114A/A115A standard.

ESD(HBM)
JEDEC specifications, that means when a device belongs to Class A it exceeds the JEDEC standard. B
Class strictly covers all the JEDEC criteria (international standard).
ESD(MM)
Symbol
A supply overvoltage is applied to each power supply pin.
A current injection is applied to each input, output and configurable I/O pin.
