MSP430FR5949 has 64 GPIO

May I know which one is correct? 

Well, if you tell me how to have 64 I/O on a 40 pin package, then I'll tell you what's correct. Otherwise it is obvious.

The FR596x comes in 48 pin QFN and has 40 I/O. That's the largest pinout currently available.

I think someone has entered the data into the wrong column, as 64 is actually the amount of FRAM (similar for the 5948 where both columns read 48)

However, these devices are still in preview state anyway.

Do you know that if TI could make a mistake for how many I/O a device has, TI could also make a mistake for how many pins a device has.

Please have your head to think carefully before any such kind of message.

Sure. But I'd say a datasheet with package information, pinout, pin funciton lists etc. which alle are consistent, would be a bi tmore trustworthy than an entry in a comparison sheet.
If you read 100 statements about a fact, it is more likely that the 99 identical statements are right than the one that differs. Even though the differing one would fit your needs better. (this may sometimes be different for opinions)

Would you believe that I thought almost the same when I did read your question? I even considered not wasting my time for an answer.

The mistake is a mistake.  If one can make one mistake, he could make thousands of mistakes.

Here, what I real need is a clarification by a TI member instead a outside "smart" guy.

I agree. But how likely isit that someone types a two digit number right one time but forgets 24 pins in a drawing, a pin function list, package size etc. ?

Please, the outside smart guy :)

I see you're hoping for a official statement like "yes, the chip has 24 pins more than drawn in the datasheet and listed in the pin function list and the port pin schematics and we just forgot to put them into the datasheet". Well, dreaming is not forbidden (except if driving a car).
However, this is an engineers forum, and daydreaming doesn't really fit the description of an engineer.

But don't hold your breath for an answer. The TI members that are found in this forum are not the engineers who are developing the devices. And have probably never seen this chip before (after all it is still in preview state and not officially released) and have acess to the very same resources as you and I have.
The major difference between them and me is that they aren't allowed to write what they think about your request. I am.

Lin,

Just posting in here to close this out.

The product folder has already been corrected to show the correct number of I/O which is 40.

In general the recommendation is to always trust the product datasheet.

Thank you for pointing out the typo!

Regards,
