STM32F103xx
Electrical characteristics
5.3.5
Supply current characteristics
The current consumption is measured as described in Figure 10: Current consumption
measurement scheme.
Maximum 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)
The parameters given in Table 11 are derived from tests performed under ambient
temperature and V supply voltage conditions summarized in Table 7.
