AVRŽ530: Migrating from AT90USB162/82 to ATmega16U2/8U2
(4 pages, revision A, updated 7/09)
The ATmega16U2/8U2 is a functionally identical, drop-in replacement for the AT90USB162/82. All devices are subject to the same qualification process and same set of production tests but since the manufacturing process is not the same, some electrical characteristics differ. In addition, the performance of some analog modules such as the Brown-Out Detector (BOD) and Power-On Rest (POR) has been improved. Some new features have also been added to the ATmega16U2/8U2.
AT90USB162/82 and ATmega16U2/8U2 have separate datasheets. This application note aims to outline the differences between the two devices and their datasheets, but there is also a detailed change log to assist the user at the end of the ATmega16U2/8U2 datasheet.
