Change Description:
This notification is to advice our customers that Atmel will introduce new revisions of the AVR microcontroller
products listed above. The new revisions are package and pin compatible to the existing revisions. They are
introduced in order to enhance the product. Actual devices changes are minimal, but for your reference they
are listed here together with enhancements that are a pure superset of existing functions.
Samples are only available in bulk and can be ordered through Atmel Sample Centre by logging on to
https://samples.atmel.com/scripts/samplecenter.dll?atmel?cmd=menu
Specific ordering codes for new die revision samples only are shown in the table below, and are available for
sample orders only until the proposed first shipment date. For all production orders, only standard existing
ordering codes will be accepted.

ATxmega64A3U-MH
ATxmega64A3U-AUK
ATxmega64A3U-MHK
Note that the K in sample ordering codes will not be marked on the package.
Changes
The new revision change the following:
•
•
•
•
Reduced current consumption
Chip erase time during programming reduced
Bonding wire material has changed from gold to copper
The I/O pins comply with the JEDEC LVTTL and LVCMOS specification and the high- and low level
input and output voltage limits reflect or exceed this specification.
See Appendix 1 for more details on changes.
Identification Method to Distinguish Change:
For packages where space allows for die ID to be part of marking, new revision material is identified as
35973I.

Quantifiable Impact on Quality & Reliability:
None
Proposed First Ship Date*: May 8, 2013
*The Proposed First Ship Date is the forecasted date that a customer may expect to receive changed product. This is determined by
the estimated date of inventory depletion on the PCN issue date. This may be affected by fluctuations in supply and demand.
Consequently, although customers should be prepared to receive changed product on this date, Atmel will continue to ship pre-changed
product until a time in which inventory has been depleted. This may result in pre-changed product being shipped to customers after this
forecasted date.
Atmel Contact: Please contact your Atmel Sales Representative or Distributor for additional information
(when replying via e-mail please include PCN number in subject line).
