ARDUINO MEGA TO ATMEGA2560 PINOUT SOFTWARE

The ATmega2560 has 32 × 8-bit general-purpose working registers with a single clock cycle access time. In order to reduce power consumption, the clocks modules not being used can be halted by using different sleep modes. All the clocks of Atmega2560 need not be active at a given time. The ATmega2560 has multiple clocks, i.e., CPU clock, I/O clock, Flash clock, ADC clock, and Asynchronous clock.

In addition, ATmega2560 contains 256KB In-System Reprogrammable Flash memory for program storage.įor software security, the Flash Program memory space is divided into two sections, the Boot Program section and the Application Program section. Single register operations can also be executed in the ALU.ĪTmega2560 has two main memory spaces: the Data Memory and the Program Memory. The ALU supports arithmetic and logic operations between registers or between a constant and a register. The program memory is In-System Reprogrammable Flash memory This concept enables instructions to be executed in every clock cycle. While one instruction is being executed, the next instruction is pre-fetched from the program memory. To maximize performance, the Atmega2560 uses an AVR-RISC (Harvard architecture) – with separate memories and buses for program and data. The resulting architecture is more code efficient and ten times faster than conventional CISC microcontrollers. All 32 registers are directly connected to the Arithmetic Logic Unit (ALU). The AVR core of ATmega2560 combines a rich set of instructions with 32 general-purpose working registers.
