Crack STM32F048C6 Microcontroller Flash Program can reset the fuse bit of mcu stm32f048c6 through laser cutting, embedded firmware of microprocessor stm32f048c6 flash memory will be extracted, the restoration of secured microcontroller stm32f048c6 can be completed.
VDD = VDDIO1 = 1.8 V ± 8%: external power supply for I/Os (VDDIO1) and digital logic. It is provided externally through VDD pins.
VDDA = from VDD to 3.6 V: external analog power supply for ADC, RCs and PLL (minimum voltage to be applied to VDDA is 2.4 V when the ADC is used). It is provided externally through VDDA pin when decoding stm32f031k4 microcontroller flash memory content. The VDDA voltage level must be always greater or equal to the VDD voltage level and must be established first.
VDDIO2 = 1.65 to 3.6 V: external power supply for marked I/Os. VDDIO2 is provided externally through the VDDIO2 pin. The VDDIO2 voltage level is completely independent from VDD or VDDA, but it must not be provided without a valid supply on VDD. The VDDIO2 supply is monitored and compared with the internal reference voltage (VREFINT).
When the VDDIO2 is below this threshold, all the I/Os supplied from this rail are disabled by hardware. The output of this comparator is connected to EXTI line 31 and it can be used to generate an interrupt. Refer to the pinout diagrams or tables for concerned I/Os list.
VBAT = 1.65 to 3.6 V: power supply for RTC, external clock 32 kHz oscillator and backup registers (through power switch) when VDD is not present.
