Typical and maximum current consumption

The MCU is put under the following conditions:



All I/O pins are in analog input mode



All peripherals are disabled except when explicitly mentioned



The Flash memory access time is adjusted with the minimum wait states number,

depending on the fHCLK frequency (refer to the table “Number of wait states according

to CPU clock (HCLK) frequency” available in the RM0471 reference manual).



When the peripherals are enabled fPCLK = fHCLK



For Flash memory and shared peripherals fPCLK = fHCLK = fHCLKS

The parameters given in Table 31 to Table 42 are derived from tests performed under

ambient temperature and supply voltage conditions summarized in Table 20: General

operating conditions.

Table 31. Current consumption in Run and Low-power run modes, code with data processing

running from Flash, ART enable (Cache ON Prefetch OFF), VDD = 3.3 V
