SBOS835C May 2017 – October 2019 TMP464
PRODUCTION DATA.
The TMP464 device has multiple 16-bit registers that hold 13-bit temperature measurement results. The 13 bits of the local temperature sensor result are stored in register 00h. The 13 bits of the four remote temperature sensor results are stored in registers 01h through 04h. The four assigned LSBs of both the local (LT3:LT0) and remote (RT3:RT0) sensors indicate the temperature value after the decimal point (for example, if the temperature result is 10.0625°C, then the high byte is 0000 0101 and the low byte is 0000 1000). These registers are read-only and are updated by the ADC each time a temperature measurement is complete. Asynchronous reads are supported, so a read operation can occur at any time and results in valid conversion results being transmitted once the first conversion is complete after power up for the channel being accessed. If after power up a read is initiated before a conversion is complete, the read operation results in all zeros (0x0000).
