DATASHEET SUMMARY
Introduction
The Atmel
®
picoPower
®
ATmega48P/PV /88P/PV /168P/PV 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/PV /88P/PV /168P/PV achieves throughputs close to 1MIPS
per MHz. This empowers system designer to optimize the device for power
consumption versus processing speed.
