AT25640A
(AT35532)
SPI EEPROM
Product Qualification
• 2325 Orchard Parkway • San Jose CA 95131 •
The AT25640A Serial Peripheral Interface EEPROM is fabricated on the AT35000
CMOS process. With the exception of HBM ESD, all tests were performed at Atmel’s
Colorado Springs Facility.
This report summarizes the product level qualification data, ESD, Latchup, and Write
Endurance for the AT25640A SPI EEPROM. This data, in conjunction with the
AT35000 Process Qualification and Reliability Report, qualifies the AT25640A.
Package specific qualification data is provided separately.
