Overview
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.
