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,1 wait state from 24 to 48 MHz and 2 wait states from 48 to 72 MHz)



Prefetch in ON (reminder: this bit must be set before clock setting and bus prescaling)



When the peripherals are enabled fPCLK2 = fHCLK and fPCLK1 = fHCLK/2



When fHCLK > 8 MHz, the PLL is ON and the PLL input is equal to HSI/2 (4 MHz) or

HSE (8 MHz) in bypass mode.

The parameters given in Table 24 to Table 30 are derived from tests performed under

ambient temperature and supply voltage conditions summarized in Table 20.
