Electrical characteristics
Static latch-up
STM8S207xx, STM8S208xx
Two complementary static tests are required on 10 parts to assess the latch-up
performance:
●
A supply overvoltage (applied to each power supply pin)
●
A current injection (applied to each input, output and configurable I/O pin) is 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.

Static latch-up class
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).
