73 / 106 page  DocID15081 Rev 10 73/106 STM32F100xC, STM32F100xD, STM32F100xE Electrical characteristics 105 Figure 25. 5 V tolerant I/O input characteristics - CMOS port Figure 26. 5 V tolerant I/O input characteristics - TTL port 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 it can sink or source up to +/-3mA. When using the GPIOs PC13 to PC15 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: • 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 7). • 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 7). |
