Therm0/1 Pin Rating

Does the internal thermal resistor in the MPC8548E processor between the Therm0 and Therm1 pins have a maximum power or current rating? I understand that it's designed to be measured with a DMM that will likely limit the current to something in the microamp range, however I'm concerned about the susceptibility of this resistor to ESD damage which could easily exceed the nominal currents this resistor was designed to see during measurement. This port is not covered by the absolute maximum ratings table that includes the I/O for this processor.

That's very helpful, thank you! Do you know if the Therm0/1 pins have ESD clamps to power and ground?

We don't have any power or current specifications for the Therm0 and Therm1 pins.

Recommended maximum static current is 3mA.

These pins passed all ESD tests during device qualification: HBM 2kV, MM 200V and CDM 500V.


Have a great day,
Andrei
