Change Description:
1. New process variant: To optimize device manufacturing yield, Atmel has introduced new design
revisions of the AVR Microcontrollers listed in the table below. The new die revisions are package and
pin out equivalents of the current die revisions.
Electrical characteristics meet the same specifications as the previous revisions.

2. Dual fab sourcing for selected devices: The optimized process variant also prepares the devices for
manufacturing in foundry to ensure an uninterrupted flow of products to meet customer production
demands. The new design revision of the products listed in the table below will be manufactured at two
different locations, Atmel’s Colorado Springs (US) wafer fabrication facility, and foundry at
Semiconductor Manufacturing International Corporation, SMIC (CN).

Identification Method to Distinguish Change:
1. All parts manufactured in the new process variant have a D printed after the date code in the top side
marking.
Ex: Top side of ATmega64-16AU will be marked:
Old process variant:

Proposed First Ship Date*:
June 1, 2010
*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 will deem this change accepted unless specific conditions of acceptance are provided in writing within 30 days from the date of this notice. All
correspondence must be sent to the Atmel Contact e-mail address listed above.
