Tool/software:
Customer is trying to use the TMP112 to read temperature data periodically (default: 4Hz) from I2C.
Would you please let me know if there is a risk of bit errors occurring due to data refresh and read timings overlapping, or what conditions make them more likely to occur?
(The extent of the risk was unclear because the data buffer structure inside the IC was unknown.)
Best regards,
Satoshi
Hello Satoshi,
In regards to reading temperature from our device please make sure you follow I2C parameters mentioned in the datasheet. We can not guarantee performance of the product outside of the datasheet. Also keep in mind the conversion time. For TMP112, it takes 11.25ms(max) to complete a full conversion. If a temperature measurement is read in-between the conversion time you will gather the temperature measurement from the last conversion and not the updated reading. I do not see risks at using the 4Hz Conversion Mode.
Best Regards,
