• 4KB 系统内可编程Flash存储器：ATmega48PA
• 8KB 系统内可编程Flash存储器：ATmega88PA

The ATmega48PA/88PA 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
ATmega48PA/88PA achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
