Electrical characteristics
STM32F20xxx
● At startup, all I/O pins are configured as analog inputs by firmware.
● All peripherals are disabled unless otherwise mentioned
● The given value is calculated by measuring the current consumption
– with all peripherals clocked off
– with one peripheral clocked on (with only the clock applied)
● The code is running from Flash memory and the Flash memory access time is equal to
3 wait states at 120 MHz
● Prefetch and Cache ON
● When the peripherals are enabled, HCLK = 120MHz, f_PCLK1 = f_HCLK/4, and
f_PCLK2 = f_HCLK/2
● The typical values are obtained for V_DD = 3.3 V and T_A= 25 °C, unless otherwise
specified.
