Thermal Calculation and Measurement

For the following discussions, PD= (VDDL x IDDL) + PI/O, where PI/O is the power dissipation of the I/O

drivers.

NOTE

The VDDSYN power dissipation is negligible.

Estimation with Junction-to-Ambient Thermal Resistance

An estimation of the chip junction temperature, T

J, in °C can be obtained from the equation:

TJ = TA +(RθJA × PD)

Input leakage current, Vin = 5.5 V (Except TMS, TRST,

DSCK and DSDI pins) for 5-V tolerant pins 1
