Additional current consumption
The MCU is placed under the following conditions:
• All I/O pins are configured in analog mode.
• The Flash memory access time is adjusted to fHCLK frequency.
• The voltage scaling is adjusted to fHCLK frequency as follows:
– Scale 3 for f
HCLK
≤ 120 MHz,
– Scale 2 for 120 MHz < f
HCLK
≤ 144 MHz
– Scale 1 for 144 MHz < f
HCLK
≤ 180 MHz. The over-drive is only ON at 180 MHz.
• The system clock is HCLK, f
PCLK1
= f
HCLK
/4, and f
PCLK2
= f
HCLK
/2.
• HSE crystal clock frequency is 8 MHz.
• Flash is enabled except if explicitly mentioned as disable.
• When the regulator is OFF, V12 is provided externally as described in Table 16:
General operating conditions
• T
A
= 25 °C.
