Power supply schemes

●

VDD = 2.0 to 3.6 V: External power supply for I/Os and the internal regulator.

Provided externally through VDD pins.

●

VSSA, VDDA = 2.0 to 3.6 V: External analog power supplies for ADC, Reset blocks, RCs

and PLL (minimum voltage to be applied to VDDA is 2.4 V when the ADC is used).

VDDA and VSSA must be connected to VDD and VSS, respectively.

●

VBAT = 1.8 to 3.6 V: Power supply for RTC, external clock 32 kHz oscillator and backup

registers (through power switch) when VDD is not present.

2.11

Power supply supervisor

The device has an integrated power on reset (POR)/power down reset (PDR) circuitry. It is

always active, and ensures proper operation starting from/down to 2 V. The device remains

in reset mode when VDD is below a specified threshold, VPOR/PDR, without the need for an

external reset circuit.

The device features an embedded programmable voltage detector (PVD) that monitors the

VDD/VDDA power supply and compares it to the VPVD threshold. An interrupt can be

generated when VDD/VDDA drops below the VPVD threshold and/or when VDD/VDDA is higher

than the VPVD threshold. The interrupt service routine can then generate a warning

message and/or put the MCU into a safe state. The PVD is enabled by software.

2.12

Voltage regulator

The regulator has three operation modes: main (MR), low power (LPR) and power down.

●

MR is used in the nominal regulation mode (Run)

●

LPR is used in the Stop mode

●

Power down is used in Standby mode: the regulator output is in high impedance: the

kernel circuitry is powered down, inducing zero consumption (but the contents of the

registers and SRAM are lost)

This regulator is always enabled after reset. It is disabled in Standby mode, providing high

impedance output.

2.13

Low-power modes

The STM32F100xx value line supports three low-power modes to achieve the best

compromise between low power consumption, short startup time and available wakeup

sources:

●

Sleep mode

In Sleep mode, only the CPU is stopped. All peripherals continue to operate and can

wake up the CPU when an interrupt/event occurs.

●

Stop mode

Stop mode achieves the lowest power consumption while retaining the content of

SRAM and registers. All clocks in the 1.8 V domain are stopped, the PLL, the HSI RC

and the HSE crystal oscillators are disabled. The voltage regulator can also be put

either in normal or in low power mode.
