Protected ATMEGA640 MCU Chip Binary Restoration is a process to unlock secured microcontroller atmega640 firmware from its flash memory and readout microprocessor atmega640 chipset flash and eeprom software data;
The device is manufactured using the Microchip high-density nonvolatile memory technology. The On-chip ISP Flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional nonvolatile memory programmer, or by an On-chip Boot program running on the AVR core.

The boot program can use any interface to download the application program in the application Flash memory. Software in the Boot Flash section will continue to run while the Application Flash section is updated while reverse engineering atmega640 microcontroller fuse bit, providing true Read- While-Write operation. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the ATmega640v is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications.

The ATmega640v AVR is supported with a full suite of program and system development tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit emulators, and evaluation kits. Each device in the ATmega640v family differs only in memory size and number of pins to recover mcu chip atmega640 heximal from flash memory. Table 2-1 summarizes the different configurations for the six devices.
