ATmega2560 Datasheet – 8-bit Microcontroller – Atmel

Part Number: ATmega2560, ATmega2560-16AU

Function : 8-bit Atmel Microcontroller with 16/32/64KB In-System Programmable Flash

Package: TQFP 100,  CBGA 100 Type

Manufacturer: ATmel




The ATmega2560 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega640 / 1280 / 1281 /  ATmega2560 / 2561 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

The high-performance, low-power Microchip 8-bit AVR RISC-based microcontroller combines 256 KB ISP flash memory, 8 KB SRAM, 4 KB EEPROM, 86 general purpose I/O lines, 32 general purpose working registers, real-time counter, six flexible timer/counters with compare modes, PWM, four USARTs, byte-oriented Two-Wire serial interface, 16-channel 10-bit A/D converter, and a JTAG interface for on-chip debugging.
