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. For proper operation, the monitoring device used should
auto-calibrate the device by canceling out the VBE variation of each MPC8544E internal diode.
The following are the specifications of the MPC8544E on-board temperature diode:
Vf > 0.40 V
Vf < 0.90 V
Operating range 2–300
μA
Diode leakage < 10 nA at 125
° C
Ideality factor over 5–150
μA at 60° C: n = 1.085 ± 0.2%
Ideality factor is defined as the deviation from the ideal diode equation:
