Electrical characteristics
STM32F103xC, STM32F103xD, STM32F103xE
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 or V (no load).
DD SS
All peripherals are disabled except if it is explicitly mentioned.
The Flash access time is adjusted to f frequency (0 wait state from 0 to 24 MHz, 1
HCLK
wait state from 24 to 48 MHZ and 2 wait states above).
●
●
Ambient temperature and V supply voltage conditions summarized in Table 10.

1. Typical values are measures at TA = 25 °C, VDD = 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 fHCLK > 8 MHz.
