32-Kbyte self-programming Flash Program Memory, 2-Kbyte SRAM, 1-KByte EEPROM, 8 Channel 10-bit A/D-converter. JTAG interface for on-chip-debug. Up to 20 MIPS throughput at 20 MHz. 1.8 - 5.5 Volt Operation.

The ATmega325P/3250P 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 ATmega325P/3250P achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
