PCN / EOL Notification ® Product Change Notification Number: CC121605 Notification Date*: July 12, 2012 Title: 2-Kbit / 4-Kbit 3-wire Interface Automotive Grade (-40C to 125C) Serial EEPROM (AT93C56A/ AT93C66A) Process Geometric Shrink and Device Enhancement Product Identification: All Packages of the Automotive Temperature Grade (-40C to +125C) AT93C56A/AT93C66A Reason for Change: Material / Composition Design / Firmware Manufacturing Location Processing / Manufacturing Logistics Quality / Reliability Change Description: Atmel has performed a process geometry shrink of the Serial EEPROM Automotive Temperature Grade AT93C56A/93C66A device (3-wire interface, 2-Kbit / 4-Kbit densities) from .35µ to .25µ. The catalog part number AT93C56A/93C66A will be replaced by AT93C56B/93C66B (see Table 1). The new devices are pin-to-pin and functionally backward compatible with the current AT93C56A/93C66A devices with the following exceptions and enhancements. Extended-VCC Operation With a growing number of application segments moving to lower supply voltages, Atmel is developing next generation devices to meet the needs of these lower voltages. These voltage ranges are used by various MCUs, SoCs, and ASICs as process lithographies for such products continue to reduce. To address these voltage requirements, Atmel has designed the AT93C56B/93C66B devices to operate over a 2.5V to 5.5V range versus the previous 2.7V to 5.5V range. Conversion to Nickel-Palladium-Gold (NiPdAu) lead finish New devices will be available in the more robust NiPdAu lead finish. The NiPdAu lead finish complies with “green” packaging standards, and all package options remain RoHS compliant and Pb/Halide/Halogen-free. The “P” designation as part of the package designator suffix in the catalog part number identifies the NiPdAu lead finish for Automotive Temperature grade product. Package material set changes Atmel assembly subcontractor, Amkor Technology Philippines, SOIC and TSSOP package material sets will change as noted in the following table: ATP SOIC TSSOP Material Set From To From To Die Attach Ablebond 84‐1 LMISR4 Ablebond 8290 Ablebond 8290 NO Change Wire Diameter 0.8 mil Au 0.6 mil Au 0.8 mil Au NO Change Mold Compound Sumitomo EME‐G700 Nitto‐GE900S Sumitomo EME‐G700 Hitachi CEL‐8240HF 10P Lead Finish Matte Sn NiPdAu Matte Sn NiPdAu ATMEL Colorado Springs • 1150 E, Cheyenne Mtn, Blvd Colorado Springs • CO 80906 USA QF-8005 Rev. 09 04/18/12 Page 1 of 4 PCN/EOL NO. CC121605 Page 2 of 4 Delivery Options To further stream line the shipping and handling process, Atmel is eliminating bulk delivery options. The new AT93C56B/93C66B devices will be offered in Tape and Reel only. Identification Method to Distinguish Change: NEW catalog part numbers use "B" suffix for the device revision (AT93C56A changes to AT93C56B and AT93C66A changes to AT93C66B). Please refer to Attachment A for part marking scheme. Table 1.
