  Low-power modes

  The STM32F103xC, STM32F103xD and STM32F103xE performance 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.

  The device can be woken up from Stop mode by any of the EXTI line. The EXTI line

  source can be one of the 16 external lines, the PVD output, the RTC alarm or the USB

  wakeup.

  <

  Standby mode

  The Standby mode is used to achieve the lowest power consumption. The internal

  voltage regulator is switched off so that the entire 1.8 V domain is powered off. The

  PLL, the HSI RC and the HSE crystal oscillators are also switched off. After entering

  Standby mode, SRAM and register contents are lost except for registers in the Backup

  domain and Standby circuitry.

  The device exits Standby mode when an external reset (NRST pin), an IWDG reset, a

  rising edge on the WKUP pin, or an RTC alarm occurs.

  Note:

  The RTC, the IWDG, and the corresponding clock sources are not stopped by entering Stop

  or Standby mode.
