1 Introduction
The ATmega164P and the ATmega324P are new and enhanced versions of the
ATmega16 and the ATmega32 respectively, and ATmega644P is a new 64kB
device with the same features. An important improvement is the possibility for low
voltage operation (1.8V) with ATmega164P/324P/644P and decreased power
consumption. ATmega164P/324P/644P also features an extra USART and can run
at frequencies up to 20 MHz.
This application note summarizes the differences between ATmega16/32 and
ATmega164P/324P/644P and is a guide to assist current ATmega16/32 users in
converting existing designs to the ATmega164P/324P/644P. Note that electrical
differences such as power consumption and I/O driving capabilities are not covered
in this document. Refer to the datasheets for detailed information on the devices.
Migration from ATmega644 is covered by AVR508: Migration from ATmega644 to
ATmega644P.
ATmega164P/324P/644P are pin compatible with ATmega163/323, and migration
between these devices is possible but not within the scope of this application note.
Refer to AVR083: Replacing ATmega163 by ATmega16 and AVR084: Replacing
ATmega323 by ATmega32 for further details.
