Maxim Integrated
Note 1: All voltages are referenced to ground. Currents entering the IC are specified as positive; currents exiting the IC are specified
as negative.
Note 2: Guaranteed by design.
Note 3: CB: Total capacitance of one bus line in pF.
Note 4: EEPROM write time begins after a STOP condition occurs.
Note 5: A decoupling capacitor to supply high instantaneous currents during EEPROM writes is recommended. A typical value is
0.01FF. VCC must be maintained above VCC(MIN), including transients, during EEPROM writes.
Note 6: VCC must be at or above 2.5V for tW after the end of an event to ensure data transfer to the EEPROM.
Note 7: Memory locations to which this specification applies: User Memory, ETC Alarm Limit, Event Counter Alarm Limit,
Configuration, Password Value.
Note 8: Memory locations to which this specification applies: Event Counter register, ETC register.
