![]() If you are designing a PCB or Perf board with this component then the following picture from the Datasheet will be useful to know its package type and dimensions. Thanks to its large number of GPIO pins, the ATMega2560 overcomes the limitations of smaller microcontrollers like the ATMega328P and allows it to communicate with more sensors and peripherals, while also leaving a large number of GPIO pins available for other tasks. This is not a major limitation, it can be overcome using level shifting circuits. The ATMega2560 uses 5V logic levels, so it might not be compatible with 3.3V sensors and other peripherals. The GPIO pins are also mapped internally to the peripherals like SPI, USART, and SPI. The easiest to use is the Arduino Mega board, which contains the ATMega3560, and can be programmed over USB from the Arduino software. It can be programmed using Atmel Studio and a dedicated programmer, or using another ATMega microcontroller and using the Arduino development environment. The ATMega2560 is an 8-bit AVR microcontroller that comes with 86 programmable GPIO pins, PWM, ADC, and timer peripherals. ![]() Note: Complete technical details can be found in the ATMega2560 datasheet given at the end of this page. Two 8-bit timer/counters, four 16-bit timer/counters.Primary processor of Arduino Mega 2560 Rev3 board is ATmega2560 chip which operates at a frequency of 16 MHz. 5 Connector Pinouts 5.1 Analog 5.2 Digital 5.3 ATMEGA16U2 JP5 5.4 ATMEGA16U2 ICSP1. It can be clocked up to 16MHz with a 5V supply. Arduino® MEGA 2560 Rev3 1 / 17 Arduino® MEGA 2560 Rev3 Modied: Product Reference Manual. It also has a wide variety of peripherals, including timers, counters, PWM generators, a comparator, and ADCs. It is based on the 8-bit AVR RISC architecture and has 256KB flash memory, 8KB SRAM, and 4KB EEPROM. The ATMega2560 from Atmel is an 8-bit low-power microcontroller that is found in the popular Arduino Mega development board.
