Secured Microchip ATMEGA640V MCU Flash Program Recovery
Secured Microchip ATMEGA640V MCU Flash Program Recovery needs to firstly crack mcu atmel atmega640v protective system and read atmega640v microcontroller flash memory content out from it;
Port A is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port A output buf- fers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port A pins that are externally pulled low will source current if the pull-up resistors are activated to recover atmega640v microcontroller flash firmware. The Port A pins are tri-stated when a reset condition becomes active, even if the clock is not running.
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port B output buf- fers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated when a reset condition becomes active, even if the clock is not running.
Port C is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port C output buf- fers have symmetrical drive characteristics with both high sink and source capability after breaking ic chip atmega640v flash protection. As inputs, Port C pins that are externally pulled low will source current if the pull-up resistors are activated. The Port C pins are tri-stated when a reset condition becomes active, even if the clock is not running.
