I need to use the stm32f103c8 and I am asking you to confirm whether I have read the following parameters correctly:
Maximum Sink and Source GPIOs Current:
"GPIOs (general-purpose inputs/outputs) can absorb or generate up to ±8 mA, and absorb or generate up to ±20 mA (with a relaxed VOL/VOH).
up to ±20 mA (with a relaxed VOL/VOH) with the exception of PC13, PC14 and PC15, which can
sink or source up to ±3 mA"
What does 'relaxed VOL/VOH' mean?
I have always known that stm32 often has a sink current of around 20 mA but would like confirmation/explanation from you.
Maximum GPIOs Input Voltage:
Input voltage on 5V tolerant pin --> Vdd+4.0V
Input voltage on any other pin --> 4.0V
Vdd:
I read Vdd = 2.0 to 3.6 V but in 'Table 6. Voltage characteristics' I read Vdd max = 4V.
How come?
Thanks to everyone
