3.3
Reset and supply management
3.3.1
Power supply schemes
●
VDD = 1.65 to 3.6 V: external power supply for I/Os and the internal regulator.
Provided externally through VDD pins.
●
VSSA, VDDA = 1.65 to 3.6 V: external analog power supplies for ADC, reset blocks, RCs
and PLL (minimum voltage to be applied to VDDA is 1.8 V when the ADC is used).
VDDA and VSSA must be connected to VDD and VSS, respectively.
3.3.2
Power supply supervisor
The device has an integrated ZEROPOWER power-on reset (POR)/power-down reset
(PDR) that can be coupled with a brownout reset (BOR) circuitry.
For devices operating between 1.8 and 3.6 V, the BOR is always active at power-on and
ensures proper operation starting from 1.8 V. After the 1.8 V BOR threshold is reached, the
option byte loading process starts, either to confirm or modify default thresholds, or to
disable BOR permanently (in which case, the VDD min value at power down is 1.65 V). Five
BOR thresholds are available through option bytes, starting from 1.8 V to 3 V. To reduce the
power consumption in Stop mode, it is possible to automatically switch off the internal
reference voltage (VREFINT) in Stop mode. The device remains in reset mode when VDD is
below a specified threshold, VPOR/PDR or VBOR, without the need for any external reset
circuit.
Note:
The start-up time at power-on is typically 3.3 ms.
For devices operating between 1.65 V and 3.6 V, the BOR is permanently disabled.
Consequently, the start-up time at power-on can be decreased down to 1ms typically.
The device features an embedded programmable voltage detector (PVD) that monitors the
VDD/VDDA power supply and compares it to the VPVD threshold. This PVD offers 7 different
levels between 1.85 V and 3.05 V, chosen by software, with a step around 200 mV. 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.
3.3.3
Voltage regulator
The regulator has three operation modes: main (MR), low power (LPR) and power down.
●
MR is used in Run mode (nominal regulation)
●
LPR is used in the Low-power run, Low-power sleep and Stop modes
●
Power down is used in Standby mode: the regulator output is high impedance: the
kernel circuitry is powered down, inducing zero consumption (but the contents of the
registers and RAM are lost are lost except for the standby circuitry (wakeup logic,
IWDG, RTC, LSI, LSE crystal 32K osc, RCC CSR)
3.3.4
Boot modes
At startup, boot pins are used to select one of three boot options:
●
Boot from Flash memory
●
Boot from System Memory
●
Boot from embedded RAM
