Description
STM32F101xF, STM32F101xG
Doc ID 17143 Rev 2
2.3.10
Clocks and startup
System clock selection is performed on startup, however the internal RC 8 MHz oscillator is
selected as default CPU clock on reset. An external 4-16 MHz clock can be selected, in
which case it is monitored for failure. If failure is detected, the system automatically switches
back to the internal RC oscillator. A software interrupt is generated if enabled. Similarly, full
interrupt management of the PLL clock is available when necessary (for example with failure
of an indirectly used external oscillator).
Several prescalers are used to configure the AHB frequency, the high-speed APB (APB2)
domain and the low-speed APB (APB1) domain. The maximum frequency of the AHB and
APB domains is 36 MHz. See Figure 2 for details on the clock tree.
2.3.11
Boot modes
At startup, boot pins are used to select one of three boot options:
●
Boot from user Flash: you have an option to boot from any of two memory banks. By
default, boot from Flash memory bank 1 is selected. You can choose to boot from Flash
memory bank 2 by setting a bit in the option bytes.
●
Boot from system memory
●
Boot from embedded SRAM
The bootloader is located in system memory. It is used to reprogram the Flash memory by
using USART1.
2.3.12
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.
2.3.13
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.
