STM32F412xE/G

Functional overview

A comprehensive set of power-saving mode allows to design low-power applications.

When the internal reset is OFF, the following integrated features are no longer supported:

•

The integrated power-on reset (POR) / power-down reset (PDR) circuitry is disabled.

•

The brownout reset (BOR) circuitry must be disabled.

•

The embedded programmable voltage detector (PVD) is disabled.

•

VBAT functionality is no more available and VBAT pin should be connected to VDD.

Voltage regulator

The regulator has three operating modes:

–

Main regulator mode (MR)

–

Low power regulator (LPR)

–

Power-down

3.19.1

Regulator ON

On packages embedding the BYPASS_REG pin, the regulator is enabled by holding

BYPASS_REG low. On all other packages, the regulator is always enabled.
