ATmega48/V / 88/V / 168/V
DATASHEET SUMMARY
Introduction
The Atmel
®
ATmega48/V/ 88/V /168/V 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/V/
88/V /168/V achieves throughputs close to 1MIPS per MHz. This empowers
system designer to optimize the device for power consumption versus
processing speed.
