STM32F105xx, STM32F107xx Description
Doc ID 15274 Rev 6 15/104
2.3.9 Power supply schemes
● V
DD
= 2.0 to 3.6 V: external power supply for I/Os and the internal regulator.
Provided externally through V
DD
pins.
● V
SSA
, V
DDA
= 2.0 to 3.6 V: external analog power supplies for ADC, Reset blocks, RCs
and PLL (minimum voltage to be applied to V
DDA
is 2.4 V when the ADC is used). V
DDA
and V
SSA
must be connected to V
DD
and V
SS
, respectively.
● V
BAT
= 1.8 to 3.6 V: power supply for RTC, external clock 32 kHz oscillator and backup
registers (through power switch) when V
DD
is not present.
2.3.10 Power supply supervisor
The device has an integrated power-on reset (POR)/power-down reset (PDR) circuitry. It is
always active, and ensures proper operation starting from/down to 2 V. The device remains
in reset mode when V
DD
is below a specified threshold, V
POR/PDR
, without the need for an
external reset circuit.
The device features an embedded programmable voltage detector (PVD) that monitors the
V
DD
/V
DDA
power supply and compares it to the V
PVD
threshold. An interrupt can be
generated when V
DD
/V
DDA
drops below the V
PVD
threshold and/or when V
DD
/V
DDA
is higher
than the V
PVD
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.
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 modes.
● 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.
2.3.12 Low-power modes
The STM32F105xx and STM32F107xx connectivity 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
OTG FS wakeup.
