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 32 for standard I/Os, and in Figure 32 for

5 V tolerant I/Os.

Figure 32. 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).

1. Refer to Figure 32: I/O input characteristics.

2. Tested in production.

3. Guaranteed by design.

4. Max(VDDXXX) is the maximum value of all the I/O supplies. Refer to Table: Legend/Abbreviations used in

the pinout table.

5. All TX_xx IO except FT_lu, FT_u, PB2 and PC3.

6. This value represents the pad leakage of the IO itself. The total product pad leakage is provided by this

formula:

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

7. To sustain a voltage higher than MIN(VDD, VDDA, VDDUSB, VLCD) +0.3 V, the internal Pull-up and Pull-Down

resistors must be disabled.

8. Refer to Ibias in Table 83: OPAMP characteristics for the values of the OPAMP dedicated input leakage

current.

9. 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).
