STM32F070xB STM32F070x6 Electrical characteristics
75
All Run-mode current consumption measurements given in this section are performed with a
reduced code that gives a consumption equivalent to CoreMark code.
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 f
HCLK
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 f
PCLK
= f
HCLK
The parameters given in Table 25 to Table 27 are derived from tests performed under
ambient temperature and supply voltage conditions summarized in Table 21: General
operating conditions.
