STMicrocontroller STM8L052C6T6 Locked Flash Memory Decryption refers to unlock the fuse bit of stm8l052 by focus ion beam and extract source code from stm8l052 mcu flash memory.
The high-density and medium+ density STM8L15xx6/8x devices feature a nested vectored interrupt controller:
Nested interrupts with 3 software priority levels
32 interrupt vectors with hardware priority
Up to 40 external interrupt sources on 11 vectors
Trap and reset interrupts
The device requires a 1.65 V to 3.6 V operating supply voltage (VDD). The external power supply pins must be connected as follows:
VSS1, VDD1, VSS2, VDD2, VSS3, VDD3, VSS4, VDD4= 1.65 to 3.6 V: external power supply for I/Os and for the internal regulator. Provided externally through VDD pins, the corresponding ground pin is VSS. VSS1/VSS2/VSS3/VSS4 and VDD1/VDD2/VDD3/VDD4 must not be left unconnected by restoring microcontroller stm8s103k3 embedded flash memory.
VSSA, VDDA = 1.65 to 3.6 V: external power supplies for analog peripherals (minimum voltage to be applied to VDDA is 1.8 V when the ADC1 is used). VDDA and VSSA must be connected to VDD and VSS, respectively.
VREF+, VREF- (for ADC1): external reference voltage for ADC1. Must be provided externally through VREF+ and VREF- pin in order to reverse engineer microcontroller stm8s105k6 structure.
VREF+ (for DAC1/2): external voltage reference for DAC1 and DAC2 must be provided externally through VREF+.
