Notes:
1. The thermal diode is not 100% tested, it is specified by design and limited characterization.
2. The thermal diode is capable of responding to thermal events of 40°C/s or faster.
3. The AMD Athlon XP processor model 8 provides a thermal diode for measuring die temperature of the processor. The
processor relies on thermal circuitry on the motherboard to turn off the regulated core voltage to the processor in response to a
thermal shutdown event. Refer to AMD Athlon Processor-Based Motherboard Design Guide, order# 24363, for thermal
protection circuitry designs.
