Electrical characteristics

STM32F051x

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 VDD or VSS (no load)

● All peripherals are disabled except when explicitly mentioned

● The Flash memory access time is adjusted to the fHCLK 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 fPCLK = fHCLK

The parameters given in Table 25 to Table 29 are derived from tests performed under

ambient temperature and supply voltage conditions summarized in Table 20.
