Decrypt ST72F321BK MCU Flash Memory Program is a process to pull the embedded firmware from st72f321bk mcu flash memory and then copy the heximal to new microcontroller;

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) which can be applied for breaking mcu st72f321j9 flash memory.

The array matrix organisation allows each sector to be erased and reprogrammed without affecting other sectors.

• Three Flash programming modes:
  • Insertion in a programming tool. In this mode, all sectors including option bytes can be pro- grammed or erased.
  • ICP (In-Circuit Programming). In this mode, all sectors including option bytes can be pro- grammed or erased without removing the de- vice from the application board.
  • IAP (In-Application Programming) In this mode, all sectors except Sector 0, can be pro- grammed or erased without removing the de- vice from the application board and while the application is running.
• ICT (In-Circuit Testing) for downloading and executing user application test patterns in RAM when attacking st72f321ar mcu protected flash memory
• Read-out protection
• Register Access Security System (RASS) to prevent accidental programming or erasing
