Actual MCU in Arduino NANO

Can anyone tell me what is the MCU on the Arduino NANO 3, is it an ATMEGA328p-au or an ATMEGA328-au?

look in boards.txt:

nano328.build.mcu=atmega328p

http://arduino.cc/en/Main/ArduinoBoardNano (From "Hardware" off the main page.)

The hardware page does not make it clear if the ATmega328P or just Atmega328 is being used, which is why the OP was asking.

It says: "Arduino Nano 3.0 (ATmega328)" on that page.

Oh, I see what you are saying. I thought it was a 328/168 question. My mistake.

AFAIK, 328P everywhere, yes.
