Description

2.3.10
Boot modes
At startup, boot pins are used to select one of three boot options:
●
Boot from User Flash
●
Boot from System Memory
●
Boot from embedded SRAM
The boot loader is located in System Memory. It is used to reprogram the Flash memory by
using USART1.
2.3.11
Power supply schemes
●
VDD = 2.0 to 3.6 V: external power supply for I/Os and the internal regulator.
Provided externally through VDD pins.
●
VSSA, VDDA = 2.0 to 3.6 V: external analog power supplies for ADC, Reset blocks, RCs
and PLL (minimum voltage to be applied to VDDA is 2.4 V when the ADC is used). VDDA
and VSSA must be connected to VDD and VSS, respectively.
●
VBAT = 1.8 to 3.6 V: power supply for RTC, external clock 32 kHz oscillator and backup
registers (through power switch) when VDD is not present.
For more details on how to connect power pins, refer to Figure 11: Power supply scheme.
2.3.12
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 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 12: Embedded reset and power control block characteristics for the values of
VPOR/PDR and VPVD.
2.3.13
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.
