CC114201 Page 2 of 5 Reason for Change: Material / Composition Design / Firmware Manufacturing Location Processing / Manufacturing Logistics Quality / Reliability Change Description: Atmel is introducing new, optimized-layout Industrial Temperature Grade (-40°C to +85°C) Serial EEPROM: AT93C56B / AT93C66B. The NEW AT93C56B / AT93C66B (1.7V to 5.5V) will now replace all AT93C56A / AT93C66A (1.8V to 5.5V) devices. In order to increase manufacturing flexibility and ensuring long term continuity of supply, Atmel will also manufacture SOIC and TSSOP packages using both Au and Cu bond wire. Atmel reserves the right to ship devices with either Au or Cu. The new packaged devices offered with the AT93C56B / AT93C66B are as the following: 8-lead JEDEC SOIC (SS): ROHS compliant/Lead-Free/Halogen-Free/NiPdAu plating. 8-lead TSSOP (X): ROHS compliant/Lead-Free/Halogen-Free/NiPdAu plating. 8-lead UDFN (MA): ROHS compliant/Lead-Free/Halogen-Free/NiPdAu plating. 8-lead XDFN (ME): ROHS compliant/Lead-Free/Halogen-Free/NiPdAu plating. 8-ball VFBGA (C): ROHS compliant/Lead-Free/Halogen-Free/SnAgCu balls. Atmel will also support die sales shipment in Wafer Form, Tape and Reel and Bumped Wafers Identification Method to Distinguish Change: NEW part numbers have been created by adding a “B” to the suffix of the catalogue part number: The AT93C56A and AT93C66A shall be identified as the AT93C56B and AT93C66B respectively. 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: The new devices are a form, fit and function equivalent of the current devices, which meet all datasheet specifications. Forecasted Availability Date: Now Last Time Buy Date: April 30, 2012 Last Ship Date: October 30, 2012 *All orders placed after the notification date are non-cancellable and non-returnable (NCNR).
