JAJSI23I September 2009 – October 2019 TMP431 , TMP432
PRODUCTION DATA.
The TMP43x contain multiple registers for holding configuration information, temperature measurement results, temperature comparator maximum, minimum, limits, and status information. These registers are described in Figure 19 and in Table 3 for the TMP431, and in Table 4 for the TMP432.
