• 16KB 系统内可编程Flash存储器：ATmega164PA
• 32KB 系统内可编程Flash存储器：ATmega324PA

The ATmega164PA/324PA 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
ATmega164PA/324PA achieves throughputs approaching 1 MIPS per MHz allowing the system
designer to optimize power consumption versus processing speed.
