STM32F103xx
Electrical characteristics
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).
