In the Absolute Maximum Ratings , changed storage temp to -55°C to +125°C; in the
Electrical Characteristics table, changed V TH , V TL based on V PUP and data retention to
40 years min at 85°C; added note to retention spec: “EEPROM writes can become
nonfunctional after the data-retention time is exceeded. Long-term storage at elevated
temperatures is not recommended; the device can lose its write capability after 10
