Looking for Tiva solution instead of Stellaris LM3S811-IQN50-C2T

Other Parts Discussed in Thread: LM3S811, TM4C1230D5PM

Hello,

I'm looking for Tiva solution.

We used Stellaris LM3S811-IQN50-C2T, but it will be EOL.

So I'm looking for similar solution. When I checked product, I found Tiva TM2C1231D5PM.

Is it suitable to change from LM3S811-IQN50-C2T? Or Can you suggest the best solution which you consider price and same feature?

Thanks.

    Hello ChangSeok,

    The recommended replacement for LM3S811, if you must replace, is TM4C1230D5PM.

    ChangSeok,

    Michael is correct in that the recommended replacement for that part is the TM4C1230D5PM.  If you have questions like this in the future (or if someone else has stumbled across this post in searching for a similar question), Sue Cozart made a post (at http://e2e.ti.com/support/microcontrollers/stellaris_arm/f/471/t/275227.aspx) talking about a new tool we have that is very helpful for questions like these.  All you have to do is type in your current part number and the tool will come up with a recommendation for a replacement part that contains similar functionality.  Of course, nothing beats reading datasheets, but the tool Sue mentioned is a good starting point for questions like these.

    @Jordan - believe yours to be great, caring and amplifying post (publicize a tool-aid) - well done.

    That said - our group has several K - that past 48 pin QFP in the field.  Our sense was/is that such 48 pin QFP devices are not included w/in rebrand.  Might you be kind enough to confirm?  (even 64 pin will not fit - our space-constrained design)  Merci...

    cb1,

    Sadly, I must confirm that we don't have any 48 pin QFP Tiva parts available at this time.  As it sounds like you're already aware, our current offerings are a 157-BGA, a 144-LQFP, a 100-LQFP, and a 64-LQFP.  I'm admittedly fairly removed from the decision process when it comes to package offerings, but I'll make sure to forward your input on to the right parties, as I know our marketing and business development teams greatly value customer input.

    @Jordan-

    Thank you - your confirmation appreciated. 

    48 pin (and smaller) ARM MCUs (from others) have gained toe-hold - often are best suited to speed demise of 8/16 bit.  (of course - not those offered here!)

    Sales/profitability always key - yet we/others sense that low-cost, simple ARM device will "win many sockets" (compact ones) in seriously, ramping numbers...
