Note 17: ε in Figure 12 represents the time required for the pullup circuitry to pull the voltage on IO up from V
Note 18: δ in Figure 12 represents the time required for the pullup circuitry to pull the voltage on IO up from V
Note 19: Current drawn from IO during the EEPROM programming interval or SHA-1 computation.
Note 20:
Note 21: Write-cycle endurance is degraded as T
Note 22: Not 100% production tested; guaranteed by reliability monitor sampling.
Note 23: Data retention is degraded as T
Note 24: Guaranteed by 100% production test at elevated temperature for a shorter time; equivalence of this production test to the
Note 25: EEPROM writes can become nonfunctional after the data-retention time is exceeded. Long-term storage at elevated tem-
Note 26:
* Intentional change; longer recovery time requirement due to modified 1-Wire front-end.
