Example of Tj calculation

Assumption :

● Package 64-pin LQFP : θja = 54.6 °C/W

● Ta = 80 °C

● ICCmax = 40 mA

● VCC = 3.5 V (VCC = AVCC = VCC_USB)

● IOH = 1 mA, VOH = VCC – 0.5 V, 12 Outputs

● IOL = 20 mA, VOL = 1.0 V, 8 Outputs

● IOL = 1 mA, VOL = 0.5 V, 12 Outputs

● Cin = 8 pF, 16 pins, Input frequency = 10 MHz

● Cload = 30 pF, 16 pins, Output frequency = 10 MHz
