69 / 154 page ![]() STM32F405xx, STM32F407xx Electrical characteristics Doc ID 022152 Rev 1 69/154 where ISW is the current sunk by a switching I/O to charge/discharge the capacitive load VDD is the MCU supply voltage fSW is the /O switching frequency C is the total capacitance seen by the I/O pin: C = CINT+ CEXT The test pin is configured in push-pull output mode and is toggled by software at a fixed frequency. Table 22. Switching output I/O current consumption(1) Symbol Parameter Conditions I/O toggling frequency (fSW) Typ Unit IDDIO Supply current VDD = 3.3 V Cext = 20 pF TBD TBD mA TBD TBD TBD TBD TBD TBD TBD TBD VDD = 3.3 V Cext = 50 pF TBD TBD TBD TBD TBD TBD TBD TBD TBD TBD VDD = 2.4V Cext = 20pF TBD TBD TBD TBD TBD TBD TBD TBD TBD TBD VDD = 2.4V Cext = 50pF TBD TBD TBD TBD TBD TBD TBD TBD TBD TBD 1.
