The RTC, the IWDG, and the corresponding clock sources are not stopped by entering Stop
or Standby mode.
DMA
The flexible 12-channel general-purpose DMAs (7 channels for DMA1 and 5 channels for
DMA2) are able to manage memory-to-memory, peripheral-to-memory and memory-to-
peripheral transfers.
The two DMA controllers support circular buffer management, removing the need for user
code intervention when the controller reaches the end of the buffer.
Each channel is connected to dedicated hardware DMA requests, with support for software
trigger on each channel. Configuration is made by software and transfer sizes between
source and destination are independent.
DMA can be used with the main peripherals: SPI, I
timers TIMx, DAC and ADC.
RTC (real-time clock) and backup registers
The RTC and the backup registers are supplied through a switch that takes power either on

They are not reset by a system or power reset, and they are not reset when the device
wakes up from the Standby mode.
The real-time clock provides a set of continuously running counters which can be used with
suitable software to provide a clock calendar function, and provides an alarm interrupt and a
periodic interrupt. It is clocked by a 32.768 kHz external crystal, resonator or oscillator, the
internal low power RC oscillator or the high speed external clock divided by 128. The
internal low-speed RC has a typical frequency of 40 kHz. The RTC can be calibrated using
an external 512 Hz output to compensate for any natural quartz deviation. The RTC features
a 32-bit programmable counter for long term measurement using the Compare register to
generate an alarm. A 20-bit prescaler is used for the time base clock and is by default
configured to generate a time base of 1 second from a clock at 32.768 kHz.
Timers and watchdogs
The high-density STM32F101xx access line devices include up to four general-purpose
timers, two basic timers, two watchdog timers and a SysTick timer.

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. 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), a IWDG reset, a
rising edge on the WKUP pin, or an RTC alarm occurs.
