content: Another new TI ARM Cortex-M4 core ? Its using the mcu with part no TM4C123GH6PM, and no reference yet at TI website.Link for the preorder at $12.99 ->https://estore.ti.com/Tiva-C-LaunchPad.aspxIt has the same price as their Stellaris Arm M4F based Launchpad, and curious why created this new series ?Maybe its a cheaper version as to their M4-"F" version since this doesn't have the "F" notation as in floating point hardware ?

content: There's a reference to the nameat the bottom of this page:QuoteIt's worth noting that the part number (TM4*) indicates it's not part of the Stellaris line (LM4*). I wonder if this will be part of the Hercules "safety microcontroller" family, possibly replacing the Cortex-M3-based TMS470M family?

content: Quote from: andersm on April 11, 2013, 05:51:34 pmStill a mystery, I'm guessing they are replacing the whole Stellaris LM4xxx lines with new line and new name "Tiva" ?The reason is I spotted its mentioned in the latest April 2013 StellarisLM4F120H5QR Rev A1/A3/B0 Errata document (Here), attached the interesting screen shot below.Also looking at the board layout, its almost identical with the Stellaris Launchpad.

content: Confirmed, the Tiva is the new name and all LM4 part numbers are now replaced with TM4xx series .Document source -> Tiva C Series ARM Cortex-M Microcontrollers ->http://www.ti.com/litv/pdf/spmt284Looks like the brand name "Stellaris" will be gone.

content: Hello All,I wanted to address some of the questions posted about Stellaris. TI has introduced a new platform for ARM Cortex-M4 based MCUs called Tiva. The Tiva C Series MCUs incorporate the same great tools, software, and support that was provided with the Stellaris microcontrollers. The new part numbers and series designations set the stage for many more exciting microcontrollers that will provide customers with a consistent look and feel across TIs Cotrex-M4 portfolio. If you have any questions I would be happy to answer.-Alex

content: This is just another great marketing gimmick. TI just wanted to drop the Stellaris brand, and quite a lot of people got fooled into believing that something new is being offered.There would be none of this confusion if they simply made the change earlier - before making all those tutorials and whatnot. But I guess this wave of commotion serves their purposes. Maybe some marketing guy thought that this will give them some free additional press.

Currently none of them carry it.
