Product Change Notification Product Change Notification Number: WC124802 Notification Date: March 13, 2013 Title: Die Revision Change for ATxmega64A4U Product Identification: ATxmega64A4U-AU ATxmega64A4U-AUR ATxmega64A4U-MH ATxmega64A4U-MHR ATxmega64A4U-CU ATxmega64A4U-CUR Reason for Change: Material / Composition Design / Firmware Manufacturing Location Processing / Manufacturing Logistics Quality / Reliability 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. Part number Ordering code for samples ATxmega64A4U-AU ATxmega64A4U-AUK ATxmega64A4U-MH ATxmega64A4U-MHK ATxmega64A4U-CU ATxmega64A4U-CUK 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 ADC calibration centering improved 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. Atmel Norway • Vestre Rosten 79 7075 Tiller • NORWAY QF-8004 Rev. 09 09/03/2012 Page 1 of 3 PCN NO. WC124802 Page 2 of 3 Identification Method to Distinguish Change: For packages where space allows for die ID to be part of marking, new revision material is identified as 35972D. Qualification Data: Available Will be available (mm/dd/yr): Not Applicable Samples: Available Will be available (mm/dd/yr): Not Applicable Quantifiable Impact on Quality & Reliability: None Proposed First Ship Date*: June 13, 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.
