ATMEGA48V-10AUR

AVR, 4KB FLASH, 256B EE, 512B RAM - 10MHz, TQFP, IND TEMP, GREEN, 1.8V, T&R

Overview

The Atmel ATmega48/88/168 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 ATmega48/88/168 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
