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

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

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

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

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)
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
