Other Parts Discussed in Thread: TMP461-SP
Hi,
I recently irradiated several TMP117 parts to xxx Mrad to see whether they would work for an application that requires sterilization. The parts still communicate over I2C but the EEPROM was erased (predictably) and now they read -256.00C and the 3 ID registers are all 0x0.
In my application I could read the EEPROM registers prior to irradiation and then write them back after irradiation. But there appear to be some hidden registers containing calibration values that I can’t read (or write).
Can you please provide information about how to read/write these hidden registers?
Thanks,
Jonathan
