Temperature Diode
The MPC8544E 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. It is recommended that each device be individually calibrated.
The following are voltage forward biased range of the on-board temperature diode:
Vf > 0.40 V
Vf < 0.90 V
An approximate value of the ideality may be obtained by calibrating the device near the expected operating
temperature. The ideality factor is defined as the deviation from the ideal diode equation:
