Electrical characteristics
STM32F031x4 STM32F031x6
Typical and maximum current consumption
The MCU is placed 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 to the fHCLK frequency:
– 0 wait state and Prefetch OFF from 0 to 24 MHz
– 1 wait state and Prefetch ON above 24 MHz
• When the peripherals are enabled fPCLK = fHCLK
The parameters given in Table 23Table 23 to Table 27 are derived from tests performed
under ambient temperature and supply voltage conditions summarized in Table 18: General
operating conditions.
