TM4C1292NCPDT: Differences between Industrial temp. grade and Extended temp. grade

Part Number: TM4C1292NCPDT

Hi,

What are exact differences between  below two parts?
TM4C1292NCPDTI3 (industrial temp. grade)
TM4C1292NCPDTT3 (extended temp. grade)
I guess they are the same die and just sorted at production test.

I checked datasheet and found below two differences.
- Device Identification 1 (DID1) register, TEMP bitfield value
- Power dissipation limits (Table 27-4)
What else?

My customer is using 'I' version.
Due to delivery issue, they cannot get 'I' version, so they are considering to use 'T' version instead.

Thanks and regards,
Koichiro Tashiro

  • Hello Tashiro-san,

    The temperature range is the only difference, and the only impact of the difference is the adjustments to power dissipation, junction temperatures, and current consumption at 105 C. All of these are spec'd in the datasheet and only impact the part different from the I version if it operates between 85C and 105C. At room temperature the parts are functionality equivalent and only the DID1 register is different to indicate the high temp part.

    Many customers are using the T version to get quicker supply and this is perfectly fine to do so for your customer without risk.
