AVR128DB28/32/48/64 Silicon Errata and Data Sheet

Clarifications

The AVR128DB28/32/48/64 devices you have received conform functionally to the current device data sheet

( www.microchip.com/DS40002247 ), except for the anomalies described in this document. The errata described in

this document will likely be addressed in future revisions of the AVR128DB28/32/48/64 devices.

Notes:

• This document summarizes all the silicon errata issues from all revisions of silicon, previous as well as current

• Refer to the Device/Revision ID section in the current device data sheet ( www.microchip.com/DS40002247 ) for

more detailed information on Device Identification and Revision IDs for your specific device, or contact your local
