_______________________________________________________________________________________
Note 1: All voltages are referenced to ground. Currents entering the IC are specified positive and currents exiting the IC are
negative.
Note 2:ICC is specified with the following conditions: SCL and SDA = VCC, RW and RH floating with Update Mode bit = 1.
Note 3: This is the minimum VCC voltage that causes NV memory to be recalled.
Note 4: This is the time from VCC > VPOR until initial memory recall is complete.
Note 5: Guaranteed by design.
Note 6: I2C interface timing shown is for Fast-Mode (400kHz) operation. This device is also backward-compatible with I2C-
Standard Mode timing.
Note 7: CB—total capacitance of one bus line in picofarads.
Note 8: EEPROM write time begins after a STOP condition occurs.
Note 9: Guaranteed by characterization.
