ATMEGA48PV-10PU

ATMEL  ATMEGA48PV-10PU  微控制器, 8位, 低功率高性能, ATmega, 10 MHz, 4 KB, 512 Byte, 28 引脚, DIP

Overview

The ATmega48P/88P/168P 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 ATmega48P/88P/168P achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
