2.2.8.2

Example of Tj Calculation

Assumption :

● Package 289-pin BGA : θja = 20 ℃/W

● Ta = 65 ℃

● ICC + ICC_DCDC = 320 mA

● VCC = 3.5 V (VCC = VCC2 = AVCC0 = AVCC_USBHS = VCC_USB = VCC_USBHS)

● 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
