Hi Sai,
Please find the thermal parameters below
Theta Ja = 37 C/W
Theta Jb = 26 C/W
Theta Jc = 7 C/W
Core Power dissipation( Pd ) = Vcc * Icc ( I am assuming Typical operating values)
Pd = 3.3 * 0.115 = 0.3795 W
Tj = Theta Ja * Pd + Ta ( ambient temp)
Tj = 99.0415 C
Tc = Tj - Theta Jc* Pd
Tc = 96.385 C
Thanks and Regards,
Pradipta.

Hi
The max temperature that the device tolerates to guarantee reliable operation will be Tj max = 125 C.
Please ensure that Tj < Tj max to guarantee reliability.
Thanks and Regards,
