Q: Operating temperature range for DS1683 is -40 ⁰C to 85 ⁰C but the Programming temp range specified is 0⁰C to 70 ⁰C. Why are they different?
A: The Programming Temperature is the range under which we guarantee the listed minimum number of EEPROM write cycles before EEPROM wearout occurs. The user can certainly write at higher temperatures (up to 85 ⁰C) but the number of EEPROM writes that can occur before EEPROM wearout is not guaranteed.
