1-Wire 4Kb EEPROM
ELECTRICAL CHARACTERISTICS (continued)
(T A = -40°C to +85°C.) (Note 1)
Note 19: The t PROG interval begins after the trailing rising edge on IO for the last time slot of the E/S byte for a valid copy scratch-
pad sequence. The interval ends once the device’s self-timed EEPROM programming cycle is complete and the current
drawn by the device has returned from I PROG to I L .
Note 20: Write-cycle endurance is degraded as T A increases.
Note 21: Not 100% production tested; guaranteed by reliability monitor sampling.
Note 22: Data retention is degraded as T A increases.
Note 23: 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 24: 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.
