The ATMEGA1281V-8MU is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 128kB ISP flash memory, 8kB SRAM, 4kB EEPROM, 54 general purpose I/O lines, 32 general purpose working registers, real time counter, six flexible timers/counters with compare modes, PWM, 4 USARTs, byte oriented 2-wire serial interface, 16-channel 10-bit A/D converter and a JTAG interface for on-chip debugging. The device achieves a throughput of 8MIPS at 16MHz and operates between 2.7 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves a throughput approaching 1MIPS per MHz, balancing power consumption and processing speed. The device is manufactured using the Atmel high-density non-volatile memory technology. The on-chip ISP flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional non-volatile memory programmer, or by an on-chip boot program running on the AVR core.
