16-Kbyte self-programming Flash Program Memory, 1-Kbyte SRAM, 512-Byte 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 ATmega164P/324P/644P 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
ATmega164P/324P/644P achieves throughputs approaching 1 MIPS per MHz allowing the system
designer to optimize power consumption versus processing speed.
