Port A (PA7:PA0)
Port B (PB7:PB0)
The ATmega164P/324P/644P have been developed and manufactured according to the most
stringent requirements of the international standard ISO-TS-16949. This data sheet contains
limit values extracted from the results of extensive characterization (Temperature and Voltage).
The quality and reliability of the ATmega164P/324P/644P have been verified during regular
product qualification as per AEC-Q100 grade 1 (–40°C to +125°C).

Port A serves as analog inputs to the Analog-to-digital Converter.
Port A also serves as an 8-bit bi-directional I/O port with internal pull-up resistors (selected for
each bit). The Port A output buffers have symmetrical drive characteristics with both high sink
and source capability. As inputs, Port A pins that are externally pulled low will source current if
the pull-up resistors are activated. The Port A pins are tri-stated when a reset condition becomes
active, even if the clock is not running.
Port A also serves the functions of various special features of the ATmega164P/324P/644P as
listed on
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port B output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port B pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port B also serves the functions of various special features of the ATmega164P/324P/644P as
