ATTM02

AME, Inc. ATTM01/ATTM02 1. General Description The ATTM01/ATTM02 are precision remote diode temperature sensors with a 2-wire System Management Bus (SMBus) serial interface. The ATTM01/ATTM02 measure: (1) Local temperature and (2) the temperature of a remote diode based transistor from Computer Processor Unit (CPU), Graphic Processor Unit (GPU) or other ASICs. The ATTM01/ATTM02 provide two system alarms: ALERT# and OVERT#. (1) ALERT# event occurs when any temperature goes outside the value that setup by preprogrammed HIGH and LOW temperature limit registers. (2) OVERT# event occurs when any temperature exceeds the OVERT# programmed limit. ATTM02 has a different SMBus address to the ATTM01. The SMBus address of the ATTM01 is 0x90 and ATTM02 is 0x94.
