Electrical characteristics
STM32F105xx, STM32F107xx
Typical current consumption
The MCU is placed under the following conditions:
All I/O pins are in input mode with a static value at VDD or VSS (no load).
All peripherals are disabled except if it is explicitly mentioned.
The Flash access time is adjusted to fHCLK 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 VDD supply voltage conditions summarized in Table 9.
Prefetch is ON (Reminder: this bit must be set before clock setting and bus prescaling)
When the peripherals are enabled fPCLK1 = fHCLK/4, fPCLK2 = fHCLK/2, fADCCLK =
fPCLK2/4

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).
