Composite Temperature (CTemp)
: This field indicates
the current temperature in degrees Celsius. If a temperature
value is reported, it should be the same temperature as the
Composite Temperature from the SMART log of hottest
controller in the NVM subsystem. The reported
temperature range is vendor specific, and shall not exceed
the range
–
60°C to +127°C (
–
76°F to +260.6°F).
Value
Detailed Description
00h-7Eh
Temperature is measured in
degrees Celsius: 0°C to
126°C (32°F to 258.8°F)
7Fh
127°C (260.6°F) or higher
80h
No temperature data or
temperature data is more the
5 seconds old.
81h
Temperature sensor failure
82h-C3h
Reserved
C4
The temperature is
–
60°C
(
–
76°F) or lower.
C5-FFh
Temperature measured in
degrees Celsius is
represented in twos
complement:
–
59°C to
–
1°C (
–
74.2°F to 30.2°F)
04
Percentage Drive Life Used (PDLU)
: Contains a vendor
specific estimate of the percentage of NVM subsystem
NVM life used based on the actual usage and the
manufacturer's prediction of NVM life. A value of 100
indicates that the estimated endurance of the NVM in the
NVM subsystem has been consumed, but may not indicate
an NVM subsystem failure. The value can be greater than
100. The value is always set to 255 if it is greater than 254.

07
PEC
: An 8-bit CRC calculated over the slave address,
command code, second slave address and returned data.
Algorithm is in SMBus Specifications.
8
08
Length of identification
: Indicates number of additional
bytes to read before encountering PEC. This value should
always be 22 (16h) in implementations of this version of
the spec.
