Input/output specifications
The product features four I/O types:
●
●
●
●
To decrease EMI (electromagnetic interference), high sink I/Os have a limited maximum
slew rate. The rise and fall times are similar to those of standard I/Os.
The analog inputs are equipped with a low leakage analog switch. Additionally, the schmitt-
trigger input stage on the analog I/Os can be disabled in order to reduce the device standby
consumption.
STM8A I/Os are designed to withstand current injection. For a negative injection current of
4 mA, the resulting leakage current in the adjacent input does not exceed 1 µA. Thanks to
this feature, external protection diodes against current injection are no longer required.
Standard I/O 2 MHz
Fast I/O up to 10 MHz
High sink 8 mA, 2 MHz
True open drain (I
