Unlock STM32F105R8 Secured Microprocessor Flash Memory and extract embedded firmware from locked MCU STM32F105R8, and then copy heximal file to new stm32f105r8 microcontroller;

The STM32F050xx family 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 very low 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 in order to replicating embedded flash program from stm32f105r8 mcu. 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 lines. The EXTI line source can be one of the 16 external lines, the PVD output, RTC alarm, I2C1 or USART1.

The I2C1 and the USART1 can be configured to enable the HSI RC oscillator for processing incoming data. If this is used, the voltage regulator should not be put in the low-power mode but kept in normal mode.

●           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 for the sake of restoring arm microcontroller stm32f103c4 flash binary, 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), a IWDG reset, a rising edge on the WKUP pins, or an RTC alarm occurs.

Note:           The RTC, the IWDG, and the corresponding clock sources are not stopped by entering Stop or Standby mode.
