EMC1063

Note: Stresses above those listed could cause damage to the device. This is a stress rating only and
functional operation of the device at any other condition above those indicated in the operation
sections of this specification is not implied. When powering this device from laboratory or
system power supplies, it is important that the Absolute Maximum Ratings not be exceeded or
device failure can result. Some power supplies exhibit voltage spikes on their outputs when the
AC power is switched on or off. In addition, voltage transients on the AC power line may appear
on the DC output. If this possibility exists, it is suggested that a clamp circuit be used.

The EMC1063 is a family of System Management Bus (SMBus) temperature sensors that monitors three temperature zones, one internal diode and two externally connected diodes. The EMC1063 is specifically designed to operate with AMD processor diodes. Alternately, the External Diode 2 channel can be configured to measure a standard thermal diode (such as a 2N3904) with Resistive Error Correction active.

An added feature to the EMC1063 is a function that automatically compares the two external temperature zones and reports the hotter of the two temperatures. Selectable conversion rates and standby mode support low-power operation. The temperature measurement ranges support two data ranges (and formats), -64°C to +127°C and -64°C to +191°C.
