EMC CHARACTERISTICS (cont’d)

13.7.3 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. For more details, re-

fer to application note AN1181.

13.7.3.1 Electro-Static Discharge (ESD)

Electro-Static Discharges (a positive then a nega-

tive 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 con-

forms to the JESD22-A114A/A115A standard.

Absolute Maximum Ratings

Notes:

1. Data based on characterization results, not tested in production.

13.7.3.2 Static and Dynamic Latch-Up (LU)

Three complementary static tests are required on

six parts to assess the latch-up 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

application note AN1181.

Electrical Sensitivities

Notes:

1. Class description: A Class is an STMicroelectronics internal specification. All its limits are higher than the JEDEC spec-

ifications, which means when a device belongs to Class A it exceeds the JEDEC standard. Class B strictly covers all the

JEDEC criteria (international standard).
