DS9405 Rev 12
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 fHCLK ≤ 120 MHz,
–
Scale 2 for 120 MHz < fHCLK ≤ 144 MHz
–
Scale 1 for 144 MHz < fHCLK ≤ 180 MHz. The overdrive is only ON at 180 MHz.
•
The system clock is HCLK, fPCLK1 = fHCLK/4, and fPCLK2 = fHCLK/2.
•
HSE crystal clock frequency is 25 MHz.
•
When the regulator is OFF, V12 is provided externally as described in Table 17:
General operating conditions
•
TA= 25 °C.
