Description STM32F103x8, STM32F103xB
in reset mode when VDD is below a specified threshold, VPOR/PDR, without the need for an external reset circuit. The device features an embedded programmable voltage detector (PVD) that monitors the VDD/VDDA power supply and compares it to the VPVD threshold. An interrupt can be generated when VDD/VDDA drops below the VPVD threshold and/or when VDD/VDDA is higher than the VPVD threshold. The interrupt service routine can then generate a warning message and/or put the MCU into a safe state. The PVD is enabled by software. Refer to Table 11: Embedded reset and power control block characteristics for the values of VPOR/PDR and VPVD.
2.3.11 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.
2.3.12 Low-power modes
The STM32F103xx 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 The 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. 16/117 DocID13587 Rev 17 Document Outline Table 1.
