A flash reminiscence is a sort of non-unstable reminiscence, which does now no longer get erased while the strength deliver is cutoff from the chip. The Atmega2560 has 256K bytes of flash reminiscence. The Atmega2560 has a complete of 6 timers, of which 2 are 8-bit timers and four are 16-bit timers. The wide variety of bits right here represents the decision of the timers, I.e. the wide variety of bits every timer can store. A comparator is largely used for evaluating voltages. It takes 2 voltages as enter and outputs the better of the two. The Atmega2560 has 1 such comparator only.
However, The Atmega328p has 32K bytes of flash memory. The Atmega328p has a complete of three timers, of which 2 are 8-bit timers and 1 are 16-bit timers. The Atmega328p has 1 such comparator only.
