1 Introduction
In order to optimize the manufacturing process and to further reduce current consumption, an optimized version of ATmega164P/324P/644P has been introduced.

The ATmega164PA/324PA/644PA is a functionally identical, drop-in replacement for the ATmega164P/324P/644P. All devices are subject to the same qualification process and same set of production tests, but as the manufacturing process is not the same some electrical characteristics differ. ATmega164P/324P/644P and ATmega164PA/324PA/644PA have separate datasheets. This application note outlines the differences between the two devices and the datasheets. There is also a detailed change log to assist the user at the end of the ATmega164PA/324PA/644PA datasheet. Remember to always use the latest revision of the device datasheet. Minor differences in typical characteristics are not discussed in this document as long as the low and h
