Unit Input capacitance CIN ¾ 3.3 7 pF Output capacitance COUT ¾ 3.3 8 pF Power dissipation capacitance CPD fIN = 10 MHz (Note 12) 3.3 25 pF Note 12: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC (opr) = CPD・VCC・fIN + ICC/16 (per bit) |
