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 non volatile write cycle; tWC after a
stop that initiates a non volatile 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, SDA = open
(6) VIL = VCC x 0.1, VIH = VCC x 0.9, fSCL = 400kHz, fSDA = 400kHz, VCC = 1.22 x VCC Min.
(7) VCC = 0V
(8) VBACK = 0V
(9) VSDA = VSCL = VCC, Others = GND or VCC
(10)VSDA = VSCL = VBACK, Others = GND or VBACK
(11)VSDA = GND to VCC, VCLK = GND or VCC
(12)IOL = 3.0mA at 5V, 1.5mA at 1.8V
(13)IOH = -1.0mA at 5V, -0.4mA at 1.8V
(14)Threshold voltages based on the higher of Vcc or VBACK.
(16)Driven by external 32.768kHz wave oscillator on X1, X2 open.
(17)Using recommended crystal and oscillator network applied to X1 and X2 (25°C) not 100% tested.
Capacitance (TA = 25°C, f = 1.0 MHz, VCC = 5V)
Note:
(1) This parameter is not 100% tested.
