Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only and the functional operation
of the device at these or any other conditions above
those indicated in the operational sections of this
specification is not implied. Exposure to absolute max-
imum rating conditions for extended periods may
affect device reliability.
DC OPERATING CHARACTERISTICS (Temperature = -40°C to +85°C, unless otherwise stated.)
OPERATING CHARACTERISTICS
Notes: (1) The device enters the Active state after any start, and remains active: for 9 clock cycles if the Device Select Bits in the Slave Address
Byte are incorrect or until 200nS after a stop ending a read or write operation.
(2) The device enters the Program state 200nS after a stop ending a write operation and continues for tWC.
(3) The device goes into the Timekeeping state 200nS after any stop, except those that initiate a nonvolatile write cycle; tWC after a stop
that initiates a nonvolatile write cycle; or 9 clock cycles after any start that is not followed by the correct Device Select Bits in the Slave
Address Byte.
(4) For reference only and not tested.
(5) VIL = VCC x 0.1, VIH = VCC x 0.9, fSCL = 400KHz
(6) VCC = 0V
(7) VBACK = 0V
(8) VSDA = VSCL=VCC, Others = GND or VCC
