TMS320x family flash memory persistence during reflow soldering

Niklas Haupt

Hi community,

At some points we are programming our TMS320x ICs before they are going to be soldered on the final PCBA just using a standalone adapter.

Is there somehow a guarantee or a rating from TI until which temperatures (during the reflow soldering) the flash memory of the ICs is persistent? Are there differences between the individual ICs in the TMS320x family?

So far we didn't have any problems, but I just want to confirm, that this is in general intended to be done.

Thanks and kind regards

Niklas

    Hello Niklas,

    In the data sheet for each device, under packaging information, there is a column in the table labeled "MSL Peak Temp". This refers to moisture sensitivity rating and peak solder temperature. In most cases this should meet the requirements of the JEDEC lead-free reflow profile.
