Electrical characteristics

Static latch-up

Two complementary static tests are required on 10 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 the

application note AN1181.

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

JEDEC specifications, that means when a device belongs to class A it exceeds the JEDEC standard. B

class strictly covers all the JEDEC criteria (international standard).

2. Available on STM8AF62xx devices only.

Thermal characteristics

In case the maximum chip junction temperature (TJmax) specified in Table 23: General

operating conditions on page 49 is exceeded, the functionality of the device cannot be

guaranteed.

TJmax, in degrees Celsius, may be calculated using the following equation:

TJmax = TAmax + (PDmax x ΘJA)

Where:

– TAmax is the maximum ambient temperature in ° C

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

– PDmax is the sum of PINTmax and PI/Omax (PDmax = PINTmax + PI/Omax)

– PINTmax is the product of IDD and VDD, expressed in Watts. This is the maximum

chip internal power.

– PI/Omax represents the maximum power dissipation on output pins

Where:

PI/Omax = 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.
