— Use star routing for the ballast supply from the VDDR supply to avoid ballast startup noise injected to VDDR
supply of the device
— Use LC inductive filtering for ADC, OSC, and PLL supplies if these are generated from common board regulators
Do not:
— Violate injection current limit per IO/All IO pins as per specifications
— Connect sensitive supplies/ground on noisy supplies/ground (that is, ADC, PLL, and OSC)
— Use SMD supply for generation of noise free supply as these are most noisy lines in the system
— Connect different VDD pins (connected together inside the device) to different potentials.

Thermal characteristics
3.5.1
General notes for specifications at maximum junction temperature
An estimate of the chip junction temperature, TJ, can be obtained from Equation 1:
TJ = TA + (RJA PD)
Eqn. 1
where:
TA
= ambient temperature for the package (°C)
