ARM Microcontroller STM32F078R8 Cracking will be able to disable the protection over its flash memory, and then readout the embedded heximal from stm32f078r8 mcu, copy firmware to new microprocessor stm32f078r8 for replication;
The internal voltage reference (VREFINT) provides a stable (bandgap) voltage output for the ADC and comparators. VREFINT is internally connected to the ADC_IN17 input channel. The precise voltage of VREFINT is individually measured for each part by ST during production test and stored in the system memory area. It is accessible in read-only mode.
This embedded hardware feature allows the application to measure the VBAT battery voltage using the internal ADC channel ADC_IN18. As the VBAT voltage may be higher than VDDA, and thus outside the ADC input range, the VBAT pin is internally connected to a bridge divider by 2. As a consequence, the converted digital value is half the VBAT voltage when unlock stm32f071v8 microprocessor flash memory.
The two 12-bit buffered DAC channels can be used to convert digital signals into analog voltage signal outputs. The chosen design structure is composed of integrated resistor strings and an amplifier in non-inverting configuration.
This digital Interface supports the following features:
Six DAC trigger inputs are used in the device. The DAC is triggered through the timer trigger outputs and the DAC interface is generating its own DMA requests.
