64-Kbyte self-programming Flash Program Memory, 4-Kbyte SRAM, 2-KByte EEPROM, 8 Channel 10-bit A/D-converter. JTAG interface for on-chip-debug. Up to 16 MIPS throughput at 16 MHz. 1.8 - 5.5 Volt Operation.
The ATmega325/3250/645/6450 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 ATmega325/3250/645/6450 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
