Power Dissipation:

Internal Chip Power Dissipation:

PINT = (VDD x (IDD –∑ IOHVDD)) + VDDIO x (IDDIO - Σ IOHVDDIO)

I/O Pin Power Dissipation:

PI/O = Σ ({VDD - VOH} x IOHVDD) + Σ (VOL x IOLVDD) + Σ ({VDDIO - VOH] x IOHVDDIO) + Σ (VOL x IOLVDDIO)

PD PINT + PI/O W
Maximum Allowed Power Dissipation PDMAX (TJ – TA)/θA W
