AVR532: Migration from ATmega48/88/168 to
ATmega48A/88A/168A
1 Introduction
The ATmega48A/88A/168A is a functionally identical, drop-in replacement for the
ATmega48/88/168. 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.
ATmega48/88/168 and ATmega48A/88A/168A 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
ATmega48A/88A/168A 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
ATmega48A/88A/168A data sheet.
