Soldering information

In order to meet environmental requirements, ST offers these devices in ECOPACK®

packages. These packages have a lead-free second level interconnect. The category of

second level interconnect is marked on the package and on the inner box label, in

compliance with JEDEC Standard JESD97. The maximum ratings related to soldering

conditions are also marked on the inner box label.

Power dissipation(1)

The maximum power dissipation is obtained from the formula PD = (TJ -TA) / RthJA. The power dissipation

of an application can be defined by the user with the formula: PD =PINT +PPORT where PINT is the chip

internal power (IDD x VDD) and PPORT is the port power dissipation depending on the ports used in the

application.
