Note:

For more information about GPIO properties, refer to the application note AN4899 "STM32

GPIO configuration for hardware settings and low-power consumption" available from the

ST website www.st.com.

All I/Os are CMOS- and TTL-compliant (no software configuration required). Their

characteristics cover more than the strict CMOS-technology or TTL parameters. The

coverage of these requirements is shown in Figure 25 for standard I/Os, and in Figure 25 for

5 V tolerant I/Os.

Figure 25. I/O input characteristics

Output driving current

The GPIOs (general purpose input/outputs) can sink or source up to ±8 mA, and sink or

source up to ± 20 mA (with a relaxed VOL/VOH).

2. Data based on characterization results, not tested in production

3. Guaranteed by design.

4. This value represents the pad leakage of the I/O itself. The total product pad leakage is provided by this formula:

ITotal_Ileak_max = 10 μA + [number of I/Os where VIN is applied on the pad] ₓ Ilkg(Max).

5. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This

PMOS/NMOS contribution to the series resistance is minimal (~10% order).
