The STM32F101R4 value line supports three low-power modes to achieve the best compromise between low power consumption to Crack ARM Microcontroller STM32F101R4, 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 for the purpose of recover MCU firmware.
Stop mode
Stop mode achieves the lowest power consumption while retaining the content of SRAM and registers in order to Motorola MC68HC08AS20 MCU Flash Copying. 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 or the RTC alarm.
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 to Crack ARM Microcontroller STM32F101R4. 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 only after Recover MC68HC908GT8 Chip Flash Data.
Standby circuitry.
The device exits Standby mode when an external reset (NRST pin), a 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.
