AME, Inc. Processor Thermal Monitor ATTM01/ATTM02 1. General Description 2. Features 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. l Remote and Local Temperature Sensing. l ±1℃ Accuracy. l Programmable HIGH/LOW Alarm Temperature Thresholds. l ALERT# Output Supports SMBus Protocol. l OVERT# Output Useful for System Shutdown. l SMBus-compatible interface. l SMBus timeout support. l Packages: SOP-8 and MSOP-8 (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. 3.

Hardware Monitor Block Control Register Remote Data Control Logic SMBCLK DXP Sigma-Delta ADC Control SMBus Codec DXN SMBDATA Status Register Local Data Control Logic ALERT _N OVER _N Hardware Monitor Interface This chip is using the 2-wire SMBus serial interface 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 accuracy of the temperature sensor under ± 1 ℃. It also uses the 2-wire SMBus serial interface. The two interrupt 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 select by initial state of ALERT# when power on or access the command index 8’h42. This chip provides two slave address 7’h1001000 and 7’h1001010 to avoid conflict with other devices. 6 Rev. B.01 AME, Inc. Processor Thermal Monitor ATTM01/ATTM02 8.

Hardware Monitor Programming Guide If want to this chip fully operation on PCB board the first step it need setting the remote and local diode offset. 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 Register 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 the ADC 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 the ADC converting temperature data to these registers before software read finish these register. In order to make parity check mechanism 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 register 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 operation 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 that ADC converting data. Rev. B.01 15 AME, Inc.
