ATMEL -8-bit Microcontroller with 64K/128K/256K Bytes In-System Programmable Flash ATmega640/V ATmega1280/V ATmega1281/V ATmega2560/V ATmega2561/V handbook
The ATmega640/1280/1281/2560/2561 family are low‑power CMOS 8‑bit microcontrollers based on the AVR enhanced RISC architecture. They deliver up to 1 MIPS per MHz and support a wide range of peripherals, making them suitable for many embedded control applications.
Key features include up to 256 KB of flash memory, multiple timer/counter units, up to 16‑channel 10‑bit ADC, several USARTs, SPI, I²C, JTAG debug interface, and extensive low‑power modes. The datasheet details pin‑outs for QFN, TQFP and CBGA packages, electrical characteristics, and ordering information.
