27 / 311 page  DS12903 Rev 2 27/311 STM32L4P5xx Functional overview 64 The ultra-low-power devices support dynamic voltage scaling to optimize its power consumption in Run mode. The voltage from the main regulator that supplies the logic (VCORE) can be adjusted according to the system’s maximum operating frequency. The main regulator operates in the following ranges: • Range 1 boost mode with the CPU running at up to 120 MHz. • Range 1 normal mode with the CPU running at up to 80 MHz. • Range 2 with a maximum CPU frequency of 26 MHz. All peripheral clocks are also limited to 26 MHz. The VCORE can be supplied by the low-power regulator, the main regulator being switched off. The system is then in Low-power run mode. • Low-power run mode with the CPU running at up to 2 MHz. Peripherals with independent clock can be clocked by the HSI16. When the MR is in use, the device with the external SMPS option allows to force an external VCORE supply on the VDD12 supply pins. When VDD12 is forced by an external source and that it is higher than the output of the internal LDO, the current is taken from this external supply and the overall power efficiency is significantly improved if using an external step down DC/DC converter. Note: The USB can only be used when the main regulator is in Range 1 boost mode. |
