modeled as a collapsed thermal resistance with thermal conductivity of 12.1 W/(m K) and an effective height of 0.1 mm. The
thermal model uses median dimensions to reduce grid. Please refer to the case outline for actual dimensions.
The thermal model uses approximate dimensions to reduce grid. The approximations used do not impact thermal performance.
Please refer to the case outline for exact dimensions.

Temperature Diode
The MPC8610 has a temperature diode on the microprocessor that can be used in conjunction with other system temperature
monitoring devices (such as Analog Devices, ADT7461). These devices use the negative temperature coefficient of a diode
operated at a constant current to determine the temperature of the microprocessor and its environment. For proper operation,
the monitoring device used should auto-calibrate the device by canceling out the VBE variation of each MPC8610’s internal
diode.
The following are the specifications of the MPC8610 on-board temperature diode:
Vf > 0.40 V
Vf < 0.90 V
