54 / 73 page  Electrical parameters STR750F 54/71 Figure 25. Connecting unused I/O pins Output driving current The GP I/Os have different drive capabilities: ● O2 outputs can sink or source up to +/-2 mA. ● O4 outputs can sink or source up to +/-4 mA. ● outputs can sink or source up to +/-8 mA or can sink +20 mA (with a relaxed VOL). In the application, the user must limit the number of I/O pins which can drive current to respect the absolute maximum rating specified in Section 3.2.2 : ● The sum of the current sourced by all the I/Os on VDD_IO, plus the maximum RUN consumption of the MCU sourced on VDD_IO, can not exceed the absolute maximum rating IVDD_IO. ● The sum of the current sunk by all the I/Os on VSS_IO plus the maximum RUN consumption of the MCU sunk on VSS_IO can not exceed the absolute maximum rating IVSS_IO. Subject to general operating conditions for VDD_IO and TA unless otherwise specified. 10k Ω UNUSED I/O PORT STR7XXX 10k Ω UNUSED I/O PORT STR7XXX VDD |
