Product Change Notification ® Product Change Notification Number: WC100902 Notification Date: March 10, 2010 Title: AVR Microcontroller Design Revision Product Identification: Affected part numbers are identified throughout the document. Reason for Change: Design Manufacturing Location Processing Quality/Reliability Logistics Material 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. Part Number ATmega8L-8PU ATmega8-16PU ATmega8L-8AU ATmega8-16AU ATmega8L-8MU ATmega8-16MU ATmega16L-8PU ATmega16-16PU ATmega16L-8AU ATmega16-16AU ATmega16L-8MU ATmega16-16MU ATmega32L-8PU Part Number ATmega32-16PU ATmega32L-8AU ATmega32-16AU ATmega32L-8MU ATmega32-16MU ATmega64L-8AU ATmega64-16AU ATmega64L-8MU ATmega64-16MU ATmega128L-8AU ATmega128-16AU ATmega128L-8MU ATmega128-16MU 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). Part Number ATmega16L-8PU ATmega16-16PU ATmega16L-8AU ATmega16-16AU ATmega16L-8MU ATmega16-16MU ATmega32L-8PU ATmega32-16PU Part Number ATmega32L-8AU ATmega32-16AU ATmega32L-8MU ATmega32-16MU ATmega128L-8AU ATmega128-16AU ATmega128L-8MU ATmega128-16MU 3. Change in production test: Production test limit for VOL parameter has been changed as shown in the table below.

WC100902 Page 2 of 2 Previous limit Symbol Parameter Output Low Voltage (Ports A - G) VOL New limit Condition Units Min Max Min Max IOL=20mA, VCC=5V - 0.7 - 0.9 V IOL=10mA, VCC=3V - 0.5 - 0.6 V This change in production test applies only to the products listed in the table below. Part Number Part Number ATmega8L-8PU ATmega8-16PU ATmega8L-8AU ATmega8-16AU ATmega8L-8MU ATmega8-16MU 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: ● New process variant: ATMEL ● MEGA64 16AU1021 ATMEL MEGA64 16AU1021D 2. The production test change applies to all material shipped after proposed first ship date. Qualification Data: Samples: available available will be available in WW___ will be available in WW___ not applicable not applicable Quantifiable Impact on Quality & Reliability: None 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.
