3.4 Cyclic

redundancy

check calculation unit (CRC)

The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit
data word and a CRC-32 (Ethernet) polynomial.

Among other applications, CRC-based techniques are used to verify data transmission or
storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a means of
verifying the Flash memory integrity. The CRC calculation unit helps compute a signature of
the software during runtime, to be compared with a reference signature generated at link-
time and stored at a given memory location.

3.5 Power

management

3.5.1

Power supply schemes



V

DD

= V

DDIO1

= 2.0 to 3.6 V: external power supply for I/Os (V

DDIO1

) and the internal

regulator. It is provided externally through VDD pins.



V

DDA

= from V

DD

to 3.6 V: external analog power supply for ADC, Reset blocks, RCs

and PLL (minimum voltage to be applied to V

DDA

is 2.4 V when the ADC is used). It is

provided externally through VDDA pin. The V

DDA

voltage level must be always greater

or equal to the V

DD

voltage level and must be established first.



V

BAT

= 1.65 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.

For more details on how to connect power pins, refer to

Figure 12: Power supply scheme

3.5.2

Power supply supervisors

The device has integrated power-on reset (POR) and power-down reset (PDR) circuits.
They are always active, and ensure proper operation above a threshold of 2 V. The device
remains in reset mode when the monitored supply voltage is below a specified threshold,
V

POR/PDR

, without the need for an external reset circuit.



The POR monitors only the V

DD

supply voltage. During the startup phase it is required

that V

DDA

should arrive first and be greater than or equal to V

DD

.



The PDR monitors both the V

DD

and V

DDA

supply voltages, however the V

DDA

power

supply supervisor can be disabled (by programming a dedicated Option bit) to reduce
the power consumption if the application design ensures that V

DDA

is higher than or

equal to V

DD

.

The device features an embedded programmable voltage detector (PVD) that monitors the
V

DD

power supply and compares it to the V

PVD

threshold. An interrupt can be generated

when V

DD

drops below the V

PVD

threshold and/or when V

DD

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.

3.5.3 Voltage

regulator

The regulator has two operating modes and it is always enabled after reset.



Main (MR) is used in normal operating mode (Run).



Low power (LPR) can be used in Stop mode where the power demand is reduced.
