FN8102.3

April 14, 2006

(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

Notes: (1) This parameter is not 100% tested.

(2) The input capacitance between x1 and x2 pins can be varied between 5pF and 19.75pF by using analog trimming registers
