ATMEGA2561 in ATmega Family
The ATmega2561 is a high-performance, low-power 8-bit microcontroller family based on the Microchip AVR enhanced RISC architecture. Known for its massive 256KB flash memory in a compact 64-pin footprint, this family executes powerful instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz. It is designed to balance processing power with energy efficiency, making it a staple for complex embedded systems requiring extensive program space and robust peripheral sets.
Variants in This Sub-Family
Variants within the ATmega2561 sub-family differ primarily in their speed grades and operating voltage ranges. The standard '16AU' variants support up to 16MHz at 4.5V-5.5V, while 'V' suffix variants like the ATmega2561V-8AU are optimized for low-voltage operation down to 1.8V with a reduced maximum clock speed of 8MHz. Packaging options include TQFP and QFN, providing flexibility for different manufacturing processes and thermal requirements.
