你的link“无嘢睇”,不明白你的问题。
AVR 是一个8Bit和32Bit 微控制器,8Bit包括ATxmega, ATmega和ATtiny。
ATmega2560是ATmega里的其中一产品。
ATmega与AVR core architecture是两回事,没法比较。 |

如果是初学者,建议使用Arduino UNO,价钱比ATmega2560的便宜得多。 |

AVR 是architecture name.
ATMEGA是AVR 的其中一种.
参考wikipedia. 没有翻译服务。
The AVR is a modified Harvard architecture machine where program and data are stored in separate physical memory systems that appear in different address spaces, but having the ability to read data items from program memory using special instructions.
Basic families
AVRs are generally classified into six broad groups:
tinyAVR — the ATtiny series
0.5–16 kB program memory
6–32-pin package
Limited peripheral set
megaAVR — the ATmega series
4–512 kB program memory
28–100-pin package
Extended instruction set (multiply instructions and instructions for handling larger program memories)
Extensive peripheral set
XMEGA — the ATxmega series
16–384 kB program memory
44–64–100-pin package (A4, A3, A1)
Extended performance features, such as DMA, "Event System", and cryptography support.
Extensive peripheral set with ADCs
Application-specific AVR
megaAVRs with special features not found on the other members of the AVR family, such as LCD controller, USB controller, advanced PWM, CAN, etc.
FPSLIC (AVR with FPGA)
FPGA 5K to 40K gates
SRAM for the AVR program code, unlike all other AVRs
AVR core can run at up to 50 MHz [5]
32-bit AVRs
