Note 5.1 In default mode, all temperatures < 0°C will be reported as 0°C.

Note 5.2 In the extended range, all temperatures < -64°C will be reported as -64°C.

Note 5.3 For the default range, all temperatures > +127.875°C will be reported as +127.875°C.

Note 5.4 For the extended range, all temperatures > +191.875°C will be reported as +191.875°C.

External Diode Connections

The EMC1402 can be configured to measure a CPU substrate transistor, a discrete 2N3904 thermal

diode, or an AMD processor diode. The diode can be connected in a variety of ways as indicated in

Figure 5.5.
