136 / 220 page ![]() Electrical characteristics STM32F469xx 136/220 DS11189 Rev 7 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 for FT I/Os is shown in Figure 39. Figure 39. FT 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) except PC13, PC14, PC15 and PI8 which can sink or source up to ±3mA. When using the PC13 to PC15 and PI8 GPIOs in output mode, the speed should not exceed 2 MHz with a maximum load of 30 pF. 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 Section 5.2. In particular: The sum of the currents sourced by all the I/Os on VDD, plus the maximum Run consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating IVDD (see Table 15). The sum of the currents sunk by all the I/Os on VSS plus the maximum Run consumption of the MCU sunk on VSS cannot exceed the absolute maximum rating IVSS (see Table 15).
