1 Introduction
In order to optimize the manufacturing process and to further reduce current
consumption, an optimized version of ATmega64 has been introduced.
The ATmega64A is a functionally identical, drop-in replacement for the ATmega64.
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.
ATmega64 and ATmega64A 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 ATmega64A 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 high limits remain the same. For detailed information about the
typical characteristics, see sections “Electrical Characteristics” and “Typical
Characteristics” of the device datasheets.
Note: This application note serves as a guide to ease migration. For complete
device details, always refer to the most recent version of the ATmega64A
datasheet.
