Electrical characteristics
92/163
All I/Os are CMOS and TTL compliant (no software configuration required). Their
characteristics cover more than the strict CMOS-technology or TTL parameters.
Output driving current
The GPIOs (general purpose input/outputs) can sink or source up to ±8 mA, and sink or
source ±20 mA (with a relaxed V
In the user application, the number of I/O pins which can drive current must be limited to
respect the absolute maximum rating specified in
