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 V is below a specified threshold, V  
, without the need for an  
DD  
POR/PDR  
external reset circuit.  
The device features an embedded programmable voltage detector (PVD) that monitors the  
/V power supply and compares it to the V threshold. An interrupt can be

generated when V /V  
drops below the V

than the V  
threshold. The interrupt service routine can then generate a warning  
PVD  
message and/or put the MCU into a safe state. The PVD is enabled by software.

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.
