Package information

Device marking for LQFP32

Figure 33 gives an example of topside marking versus pin 1 position identifier location.

The printed markings may differ depending on the supply chain.

Other optional marking or inset/upset marks depending on supply-chain operations, are not

indicated below.

1. Parts marked as “ES”, “E” or accompanied by an Engineering Sample notification letter, are not yet

qualified and therefore not approved for use in production. ST is not responsible for any consequences

resulting from such use. In no event will ST be liable for the customer using any of these engineering

samples in production. ST’s Quality department must be contacted prior to any decision to use these

engineering samples to run a qualification activity.

Thermal characteristics

The maximum chip-junction temperature, TJ max, in °C, may be calculated using the

following equation:

TJ max = TA max + (PD max × ϴJA)

Where:

•

TA max is the maximum ambient temperature in °C

•

ϴJA is the package junction-to-ambient thermal resistance in °C/W

•

PD max is the sum of PINT max and PI/O max (PD max = PINT max + PI/Omax),

•

PINT max is the product of IDD and VDD, expressed in Watts. This is the maximum chip

internal power.

PI/O max represents the maximum power dissipation on output pins where:

PI/O max= Σ(VOL × IOL) + Σ((VDD – VOH) × IOH),

taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the

application.
