Datasheet
The processor SMBus thermal sensor and thermal reference byte may be used to monitor long term
temperature trends, but cannot be used to manage the short term temperature of the processor or
predict the activation of the thermal control circuit. As mentioned earlier, the processors high
thermal ramp rates make this infeasible. Refer to the thermal design guidelines listed in Section 1.2
for more details.
The SMBus thermal sensor feature in the processor cannot be used to measure TCASE.The TCASE
specification in Chapter 6.0 must be met regardless of the reading of the processor's thermal sensor
in order to ensure adequate cooling for the entire processor. The SMBus thermal sensor feature is
only available while VCC and SM_VCC are at valid levels and the processor is not in a low-power
state.
7.4.5
Thermal Sensor Supported SMBus Transactions
The thermal sensor responds to five of the SMBus packet types: Write Byte, Read Byte, Send Byte,
Receive Byte, and Alert Response Address (ARA). The Send Byte packet is used for sending one-
shot commands only. The Receive Byte packet accesses the register commanded by the last Read
Byte packet and can be used to continuously read from a register. If a Receive Byte packet was
preceded by a Write Byte or send Byte packet more recently than a Read Byte packet, then the
‘S’ represents the SMBus start bit, ‘P’ represents a stop bit, ‘Ack’ represents an acknowledge, and
‘///’ represents a negative acknowledge (NACK). The shaded bits are transmitted by the thermal
sensor, and the bits that aren’t shaded are transmitted by the SMBus host controller. Table 44 shows
the encoding of the command byte.
