Note 1: Specifications at -40°C are guaranteed by design and characterization only and not production tested.
Note 2: Guaranteed by design, characterization, and/or simulation only and not production tested.
Note 3: This specification is valid for each 8-byte memory row.
Note 4: Write-cycle endurance is degraded as TA increases.
Note 5: Not 100% production tested; guaranteed by reliability monitor sampling.
Note 6: Data retention is degraded as TA increases.
Note 7: Guaranteed by 100% production test at elevated temperature for a shorter time; equivalence of this production test to data
sheet limit at operating temperature range is established by reliability testing.
Note 8: EEPROM writes can become nonfunctional after the data retention time is exceeded. Long-time storage at elevated tem-
peratures is not recommended; the device can lose its write capability after 10 years at +125°C or 40 years at +85°C.
Note 9: All values are referred to VIH(MIN) and VIL(MAX) levels.
Note 10: See Figure 3.
Note 11: CB = Total capacitance of one bus line in pF. If mixed with high-speed-mode devices, faster fall times according to I2C
Bus Specification v2.1 are allowed.
