2.2.7.2

Example of Tj calculation

Assumption :

● Package 64-pin LQFP : θja = 41.3 °C/W

● Ta = 100 °C

● ICCmax = 40 mA

● VCC = 3.5 V (VCC = AVCC0 = VCC_USB)

● IOH = 1 mA, VOH = VCC – 0.5 V, 8 Outputs

● IOL = 20 mA, VOL = 1.0 V, 6 Outputs

● IOL = 1 mA, VOL = 0.5 V, 8 Outputs

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

● Cload = 30 pF, 8 pins, Output frequency = 10 MHz

Leakage current of IO = Σ (VOL × IOL) / Voltage + Σ ((VCC - VOH) × IOH) / Voltage

= (20 mA × 1 V) × 6 / 3.5 V + (1 mA × 0.5 V) × 8 / 3.5 V + ((VCC - (VCC - 0.5 V)) × 1 mA) × 8 / 3.5 V

= 34.29 mA + 1.14 mA + 1.14 mA

= 36.6 mA
