Supply current characteristics

The following current consumption specified for the ST7 functional operating modes over

temperature range does not take into account the clock source current consumption. To get

the total device consumption, the two current values must be added.

EMC characteristics

Susceptibility tests are performed on a sample basis during product characterization.

6.5.1

Functional EMS (electromagnetic susceptibility)

Based on a simple running application on the product (toggling 2 LEDs through I/O ports),

the product is stressed by two electromagnetic events until a failure occurs (indicated by the

LEDs).

●

ESD: Electrostatic discharge (positive and negative) is applied on all pins of the device

until a functional disturbance occurs. This test conforms with the IEC 1000-4-2

standard.

●

conforms with the IEC 1000-4-4 standard.

A device reset allows normal operations to be resumed. The test results are given in the

table below based on the EMS levels and classes defined in application note AN1709.
