(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
