63 / 128 page ![]() STM32F37x Electrical characteristics Doc ID 022691 Rev 3 63/128 Figure 11. Typical VBAT current consumption (LSE and RTC ON/LSEDRV[1:0]='00') Typical current consumption The MCU is placed under the following conditions: ● VDD = VDDA = VDDSD12 = VDDSD3 = 3.3 V ● All I/O pins are in analog input configuration ● The Flash access time is adjusted to fHCLK frequency (0 wait states from 0 to 24 MHz, 1 wait state from 24 to 48 MHz and 2 wait states from 48 MHz to 72 MHz) ● Prefetch is ON ● When the peripherals are enabled, fAPB1 = fAHB/2, fAPB2 = fAHB ● PLL is used for frequencies greater than 8 MHz ● AHB prescaler of 2, 4, 8, 16 and 64 is used for the frequencies 4 MHz, 2 MHz, 1 MHz, 500 kHz and 125 kHz respectively 0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 25°C 60°C 85°C 105°C 1.65 V 1.8 V 2 V 2.4 V 2.7 V 3 V 3.3 V 3.6 V |
