Notes:
1. The temperature is the junction temperature of the die. The thermal assist unit’s raw output does not indicate an
absolute temperature, but must be interpreted by software to derive the absolute junction temperature. For
information about the use and calibration of the TAU, see Freescale Application Note AN1800/D, Programming the
Thermal Assist Unit in the MPC750 Microprocessor.
2. The comparator settling time value must be converted into the number of CPU clocks that need to be written into
the THRM3 SPR.
3. Guaranteed by design and characterization.
