Electrical characteristics
STM32F20xxx
Typical and maximum current consumption
The MCU is placed under the following conditions:
● At startup, all I/O pins are configured as analog inputs by firmware.
● All peripherals are disabled except if it is explicitly mentioned.
● The Flash memory access time is adjusted to fHCLK frequency (0 wait state from 0 to
30 MHz, 1 wait state from 30 to 60 MHz, 2 wait states from 60 to 90 MHz and 3 wait
states from 90 to 120 MHz).
● When the peripherals are enabled HCLK is the system clock, fPCLK1 = fHCLK/4, and
fPCLK2 = fHCLK/2, except is explicitly mentioned.
● The maximum values are obtained for VDD = 3.6 V and maximum ambient temperature
(TA), and the typical values for TA= 25 °C and VDD = 3.3 V unless otherwise specified.

1. Based on characterization, tested in production at VDD max and fHCLK max with peripherals enabled.
2. External clock is 4 MHz and PLL is on when fHCLK > 25 MHz.
3. When the ADC is on (ADON bit set in the ADC_CR2 register), add an additional power consumption of 1.6 mA per ADC for
the analog part.
4. In this case HCLK = system clock/2.
