Arduino® MEGA 2560 Rev3

3.3 Processor

Primary processor of Arduino Mega 2560 Rev3 board is ATmega2560 chip which operates at a frequency of 16
MHz. It accomodates a large number of input and output lines which gives the provision of interfacing many
external devices. At the same time the operations and processing is not slowed due to its significantly larger RAM
than the other processors. The board also features a USB serial processor ATmega16U2 which acts an interface
between the USB input signals and the main processor. This increases the flexibility of interfacing and connecting
peripherals to the Arduino Mega 2560 Rev 3 board.
