Crack ST72F321M9 Secured Microcontroller and pull the embedded firmware from st72f321m9 locked flash memory, copy heximal file into new microprocessor st72f321m9 memory;
the MCU is capable of addressing 64K bytes of memories and I/O registers. The available memory locations consist of 128 bytes of register locations, up to 2Kbytes of RAM and up to 60Kbytes of user program memory when st72f321bk mcu flash memory program decryption. The RAM space includes up to 256 bytes for the stack from 0100h to 01FFh.
The highest address bytes contain the user reset and interrupt vectors.
IMPORTANT: Memory locations marked as “Re- served” must never be accessed. Accessing a re- seved area can have unpredictable effects on the device.

The ST7 dual voltage High Density Flash (HDFlash) is a non-volatile memory that can be electrically erased as a single block or by individu- al sectors and programmed on a Byte-by-Byte ba- sis using an external VPP supply.
The HDFlash devices can be programmed and erased off-board (plugged in a programming tool) or on-board using ICP (In-Circuit Programming) or IAP (In-Application Programming) even in the process of decoding mcu st72f321r9 locked memory file. The array matrix organisation allows each sector to be erased and reprogrammed without affecting other sectors.
