Electrical characteristics
STM32F103xF, STM32F103xG
Typical current consumption
The MCU is placed under the following conditions:
● All I/O pins are in input mode with a static value at V_DD or V_SS (no load).
● All peripherals are disabled except if it is explicitly mentioned.
● The Flash access time is adjusted to f_HCLK frequency (0 wait state from 0 to 24 MHz, 1
wait state from 24 to 48 MHZ and 2 wait states above).
● Ambient temperature and V_DD supply voltage conditions summarized in Table 10.
● Prefetch is ON (Reminder: this bit must be set before clock setting and bus prescaling)
When the peripherals are enabled f_PCLK1 = f_HCLK/4, f_PCLK2 = f_HCLK/2, f_ADCCLK = f_PCLK2/4

1. Typical values are measures at T_A = 25 °C, V_DD = 3.3 V.
2. Add an additional power consumption of 0.8 mA per ADC for the analog part. In applications, this
consumption occurs only while the ADC is on (ADON bit is set in the ADC_CR2 register).
3. External clock is 8 MHz and PLL is on when f_HCLK > 8 MHz.
