TMS320F28P550SJ: Question about 100pin LQFP package

Part Number: TMS320F28P550SJ


Tool/software:

Hi Champs,

This question is asked for F28P55x, F28003x and F28004x 100pin LQFP package.

In datasheet 11.1 Packaging Information(page 264), 100pin package is "PQFP" package. Now customer want to check if the data is correct for "LQFP" package? I searched on the Internet, the difference between LQFP and PQFP is the thickness. So is this thickness information in the datasheet for LQFP or PQFP?

Best Regards,

    Julia,

    The mechanicals at the end of the DS are correct.  Please see this reference from TI.com package search, where this package is in the LQFP family:

    I'm not sure why there is PQFP designator in the mechanicals, but this is sourced from TI packaging team and not C2000 specific.

    Is there any concern with mechanical?

    Hi Matt,

    When customer documented the information for this device, they noticed that the datasheet had two package names, "PQFP" and "LQFP". Therefore, customer is worried that there is an error in the size value in our datasheet.

    So please help clarify that the chip size in the datasheet is correct, and then the correct package name is "LQFP", and the customer should ignore "PQFP". Is this correct?

    Also, I think we should remove "PQFP" from datasheet to avoid misunderstandings. Thanks!

    Best Regards,

    Julia

    Julia,

    I understand, I need to follow up with the packaging team on getting this clarified.  Looking at the other mechanicals in the DS I also do not see this additional labeling, so I think it is not needed(and as you said potentially confusing).

    Best,

    Matthew
