7.3 Feature Description

7.3.1 Temperature Measurement Data

The local and remote temperature sensors have a resolution of 12 bits (0.0625°C). Temperature data that

result from conversions within the default measurement range are represented in binary form, as shown in the

Standard Binary column of Table 7-1. Any temperatures above 127°C result in a value that rails to 127.9375

(7FFh). The device can be set to measure over an extended temperature range by changing bit 2 (RANGE) of

the configuration register from low to high. The change in measurement range and data format from standard

binary to extended binary occurs at the next temperature conversion. For data captured in the extended

temperature range configuration, an offset of 64 (40h) is added to the standard binary value, as shown in the

Extended Binary column of Table 7-1. This configuration allows measurement of temperatures as low as –64°C,

and as high as 191°C; however, most temperature-sensing diodes only operate within the range of –55°C to

150°C. Additionally, the TMP9R01-SEP and TMP9R01-SP are specified only for ambient temperatures ranging

from –55°C to 125°C; parameters in the Section 6.1 table must be observed.
