In the part number ATmega328p, what does the p refer to?

In AVR part numbers, the letter suffix flags a variant with a special feature. The P in ATmega328P identifies it as a PicoPower device, meaning it’s an ultra-low-power version designed to draw less current in active and sleep modes. That low-power capability is the reason this suffix exists, and it’s a helpful cue when selecting parts for battery-powered projects. The other phrases aren’t the official suffix meaning used for this family, so they don’t indicate the PicoPower variant.
