ATTM01/ATTM02
1. General Description
The ATTM01/ATTM02 are precision remote diode tem-
perature sensors with a 2-wire System Management Bus
(SMBus) serial interface. TheATTM01/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 otherASICs.
l Remote and Local Temperature Sensing.
l ±1℃Accuracy.
l Programmable HIGH/LOWAlarmTemperature
Thresholds.
l ALERT# Output Supports SMBus Protocol.
l OVERT# Output Useful for System Shutdown.
l SMBus-compatible interface.
l SMBus timeout support.
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.
l Packages: SOP-8 and MSOP-8
(2) OVERT# event occurs when any temperature ex-
ceeds the OVERT# programmed limit.
ATTM02 has a different SMBus address to theATTM01.
The SMBus address of theATTM01 is 0x90 andATTM02
is 0x94.

Hardware Monitor Interface
This chip is using the 2-wire SMBus serial inter-
face to control the hardware monitor function. The
major function of the hardware monitor is monitored
the remote diode and local diode temperature. It also
using the trimmed mechanism to control the accu-
racyof the temperature sensor under ± 1 ℃. It also
uses the 2-wire SMBus serial interface. The two in-
terrupt outputs ALERT# and OVER# are active low
at default state and can change these outputs to
active high when set bit 1 of register address 8’ h31
to logic one. The slave address of SMBus can se-
lect by initial state of ALERT# when power on or
access the command index 8’ h42. This chip pro-
vides two slave address 7’ h1001000 and
7’ h1001010 to avoid conflict with other devices.

The S denotes Start Bit. Address represents slave address. The COMMAND Byte is selects that register you are
reading from. TheAddress1 is due to change in data flow direction. The DATA Byte is reads from the register set by the
command byte. The in above table the red color denotes Slaver transmission.

If want to this chip fully operation on PCB board the
first step it need setting the remote and local diode off-
set. This offset can eliminate the PCB trace, binding
wire loading. When software setting the offset register
to reduce side effect of PCB trace to minimum then the
temperature data accuracy is 0.5 ℃.
Setting the bit 5, bit4 of Thermal Sensor Control Reg-
ister can enable or disable the digital filter. When these
bit set to logic one then the digital filter will be turned
on, otherwise, these digital filter will be turned off.
In this chip has a parity check mechanism to avoid
the software reading remote or local temperature data
and theADC converting temperature into this register. In
other words, when the software reading the temperature
data (register 8’ h0, 8’ h1, 8’ h10, 8’ h30) and at the
same time the ADC want converting temperature data to
register 8’ h0, 8’ h1, 8’ h10, or 8’ h30 then the parity
check mechanism will halt theADC converting tempera-
ture data to these registers before software read finish
these register. In order to make parity check mecha-
nism can work well when read the temperature data it
need read the high byte temperature data at first and
continue read the low byte temperature data, i.e., read
the temperature data register the first need read regis-
ter 8’ h0 or 8’ h1 and consecutive read register 8’ h30
or 8’ h10.
When the software want to reduce the supply current
it can enable the one shot mode and this mode opera-
tion only at standby mode, i.e., bit 6 of Configuration
register set to “1”. The software need set the bit 1 of
register 8’ hF address to “1” and consecutive set this
bit to “1” to generate one pulse signal.
The bit 7 (BUSY) of status register will not effect the
reading temperature data. Because of this bits only show
thatADC converting data.
