5 / 28 page 5 FN8099.1 September 15, 2005 (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 AC CHARACTERISTICS AC Test Conditions Figure 1.
