Electrical characteristics STM32F051x
46/105 Doc ID 022265 Rev 3
Typical and 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
DD
or V
SS
(no load)
● All peripherals are disabled except when explicitly mentioned
● The Flash memory access time is adjusted to the f
HCLK
frequency (0 wait state from 0
to 24 MHz and 1 wait state above 24 MHz)
● Prefetch is ON when the peripherals are enabled, otherwise it is OFF (to enable
prefetch the PRFTBE bit in the FLASH_ACR register must be set before clock setting
and bus prescaling)
● When the peripherals are enabled f
PCLK
= f
HCLK
The parameters given in Ta ble 2 5 to Ta bl e 2 9 are derived from tests performed under
ambient temperature and supply voltage conditions summarized in Table 2 0.
