ABRIDGED DATA SHEET

Electrical Characteristics (continued)

= -40NC to +85NC, unless otherwise noted.) (Note 1)

Note 23: Data retention is tested in compliance with JESD47G.

Note 24: Guaranteed by 100% production test at elevated temperature for a shorter time; equivalence of this production test to the-

data sheet limit at operating temperature range is established by reliability testing.

Note 25: EEPROM writes can become nonfunctional after the data-retention time is exceeded. Long-term storage at elevated tem-

peratures is not recommended.

Note 26: Refer to the full data sheet.
