ATMEGA48V-10AU Datasheet

8-bit Atmel Microcontroller with 4/8/16K Bytes In-System Programmable Flash


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.
