Programming the Thermal Assist Unit in the MPC750 Microprocessor

PublishTime：2021-10-26

●This application note descnbes example software to program the thermal assist unit(TAU) feature of the MPC750 family of microprocessors. The TAU is an on-chip sensor that measures the instantaneous junction temperature of the microprocessor. TAU operation is in the" Thermal Assist Unit section of the MPC750 RISC Microprocessor anual (order #. MPC750UM/AD). Some of the information from the user argely repeated in Section ll,"Themal Assist Overview. and Section 1.2,"Thermal Assist Unit Operation, as a background to understanding the software, but this application note should be used in conjunction with the user's manual. The following technical papers descnbe the physical implementation of the TAU:
■Hector Sanchez, Ross Philip, Jose Alvarez, Gianfranco Gerosa, "A CMOS Tempera- are Sensor for Powerpc RISC Microprocessor, Digest of Technical Papers 1997, IEEE Symposium on VLSI Circuits", pp. 13-14 June 1997
■ Hector Sanchez, Belli Kuttanna, Tim olson, Mike Alexander, Gian Gerosa, Ross Philip, and Jose Alvarez, Thermal Management System for High performance RISC Microprocessor, Digest of Technical Papers COMPCON97. pp. 325-331
●Note that the MPC750 is implemented in both a 2.6-volt version (part number MPC750A)and a 1.9-volt version (MPC750P). The functionality of the tau will be identical in all
members of the MPC750 family though process differences may affect the accuracy of the thermal measurement reported. See the MPC750 Hardware Specification (order #: MPC750EC/AD) forelectrical details including the resolution (4°C assumed in this application note) and accuracy (normally noworse than ± 16°C) of the TAU. A calibration capability, described in this application note, can beprogrammed to improve the accuracy of the temperature value returned.
