External clock source characteristics
High-speed external user clock generated from an external source
The characteristics given in Table 19 result from tests performed using an high-speed
external clock source, and under the ambient temperature and supply voltage conditions
summarized in Table 8.
Table 18. Peripheral current consumption
Peripheral
Typical consumption at 25 °C(1)
1.
fHCLK = 36 MHz, fAPB1 = fHCLK/2, fAPB2 = fHCLK, default prescaler value for each peripheral.

ADC1(3)
3. Specific conditions for ADC: fHCLK = 28 MHz, fAPB1 = fHCLK/2, fAPB2 = fHCLK, fADCCLK = fAPB2/2 . When
ADON bit in the ADC_CR2 register is set to 1, the consumption added is equal to 0.65 mA. When the ADC
is enabled, a current consumption is added equal to 0.05 mA.
