Electrical Characteristics
The total power dissipation can be calculated from:
PD = PINT + PIO
PINT = Chip Internal Power Dissipation, [W]
â PIO = i RDSON â
IIOi2
PIO is the sum of all output currents on I/O ports associated with VDDX, whereby
RDSON = V--I--O-O----L-L--;for outputs driven low
RDSON = V-----D----D-----3I--O-5----Hâ-----V----O-----H---;for outputs driven high
Two cases with internal voltage regulator enabled and disabled must be considered:
1. Internal voltage regulator disabled
PINT = IDD â
VDD + IDDPLL â
VDDPLL + IDDA â
VDDA
2. Internal voltage regulator enabled
PINT = IDDR â
VDDR + IDDA â
VDDA
