Secured STM8L001F3 Microcontroller Flash Memory Unlocking includes breaking stm8l001f3 microCPU flash memory protection by fuse bit and extract embedded firmware in the format of heximal from MCU STM8L001F3;

The 8-bit STM8 core is designed for code efficiency and performance with an Harvard architecture and a 3-stage pipeline.

It contains 6 internal registers which are directly addressable in each execution context, 20 addressing modes including indexed indirect and relative addressing, and 80 instructions by unlocking microcontroller stm8s103f3 flash memory protection.

Harvard architecture

3-stage pipeline

32-bit wide program memory bus – single cycle fetching most instructions

X and Y 16-bit index registers – enabling indexed addressing modes with or without offset and read-modify-write type data manipulations

8-bit accumulator

24-bit program counter – 16 Mbyte linear memory space

16-bit stack pointer – access to a 64 Kbyte level stack

8-bit condition code register – 7 condition flags for the result of the last instruction.

20 addressing modes

Indexed indirect addressing mode for lookup tables located anywhere in the address space in order to unlock microprocessor stm8s103k3 flash memory.

Stack pointer relative addressing mode for local variables and parameter passing.

80 instructions with 2-byte average instruction size

Standard data movement and logic/arithmetic functions

8-bit by 8-bit multiplication

16-bit by 8-bit and 16-bit by 16-bit division

Bit manipulation

Data transfer between stack and accumulator (push/pop) with direct stack access

Data transfer using the X and Y registers or direct memory-to-memory transfers
