60 / 96 page  Electrical characteristics STM32F103x8, STM32F103xB 60/96 Doc ID 13587 Rev 12 Figure 27. 5 V tolerant I/O input characteristics - CMOS port Figure 28. 5 V tolerant I/O input characteristics - TTL port Output driving current The GPIOs (general-purpose inputs/outputs) can sink or source up to ±8 mA, and sink or source up to ±20 mA (with a relaxed VOL/VOH). 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). |
