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 V
DD
or V
SS
(no load)
• All peripherals are disabled except when explicitly mentioned
• The Flash memory access time is adjusted to the f
HCLK
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 f
PCLK2
= f
HCLK
and f
PCLK1
= f
HCLK/2
• When f
HCLK
> 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 29 to Table 35 are derived from tests performed under
ambient temperature and supply voltage conditions summarized in Table 23.
