Preliminary Information
X1288
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
(9) VSDA =VSCL=VBACK, Others = GND or VBACK
(10)VSDA = GND or VCC, VSCL = GND or VCC, VRESET = GND or VCC
(11)IOL = 3.0mA at 5.5V, 1.5mA at 2.7V
(12) IOH = -1.0mA at 5.5V, -0.4mA at 2.7V
(13)Threshold voltages based on the higher of Vcc or Vback.
(14)Using recommended crystal and oscillator network applied to X1 and X2 (25°C).
(15)Typical values are for TA = 25°C
Capacitance TA = 25°C, f = 1.0 MHz, VCC = 5V
