EMC CHARACTERISTICS (Cont’d)

12.7.3 Absolute Maximum Ratings (Electrical

Sensitivity)

Based on three different tests (ESD, LU and DLU)

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 the application note AN1181.

12.7.3.1 Electrostatic Discharge (ESD)

Electrostatic 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). This test conforms to the JESD22-

A114A/A115A standard.

Absolute Maximum Ratings

Notes:

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

12.7.3.2 Static latchup

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, out-

put and configurable I/O pin) are performed on

each sample. This test conforms to the EIA/JESD

78 IC latchup standard. For more details, refer to

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

JEDEC criteria (international standard).
