Input/output specifications
The product features four different 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. Selected I/Os include
a low leakage analog switch.
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. External
protection diodes are no longer required.
