91 / 135 page  Electrical characteristics STM32F401xB STM32F401xC 91/135 DocID024738 Rev 6 Figure 30. 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 and PC15 which can sink or source up to ±3mA. When using the PC13 to PC15 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 6.2. 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 ΣIVDD (see Table 12). • 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 ΣIVSS (see Table 12). Output voltage levels Unless otherwise specified, the parameters given in Table 55 are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 14. All I/Os are CMOS and TTL compliant. |
