What's going on with Tiva?

Recommended Posts

Way back when, TI effectively rebranded Stellaris as Tiva as part of the transition from Luminary Micro to TI and from Cortex-M3 to Cortex-M4.  Now they seem to be abandoning Tiva as well; if you search for Tiva on ti.com, it takes you to "TivaWare for TM4C12x MCUs (Formerly Tiva MCUs)".  Products->Microcontrollers no longer has a Tiva section either; instead, the Cortex-M4 are hidden under "Control + Automation" -> "TM4C12x".

 

Any idea what's going on here?

I suspect, but do not really know 100% this may have to do with the new MSP432 launchpads ? I was kind of curious what the real difference were between the new launchpads ( MSP432's ), and the older LM4F120 boards. I have not really had the time to go looking in earnest yet myself. One thing that maybe I misunderstood while listening to a youtube video was that the newer MSP432 has an on die DSP ?!

 

Anyway, the MCU I believe is an M4F part I believe but . . .again haven't had much time to check it out really.

 

EDIT:

Seems this is FUD. Checked out the webpage quick and nothing there mentions a DSP.

MSP432 uses a Cortex-M4F core, which includes an instruction set extension designed for signal processing tasks. It has faster MAC and SIMD instructions with support for saturation arithmetic. I think there might be some marketing at work (from ARM) in calling it DSP, but it's nice to have nonetheless.

 

The DSP instruction set reference is here: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.100166_0001_00_en/ric1417449098079.html

I don't think the MSP432 is in the same niche as Tiva. MSP432 is lower power and has peripherals derived from MSP430 family. The peripherals are low-power, but less full-featured than those on the tiva. CPU clock speed is lower and peripherals clock speeds are even lower than that.

Well I suppose that answers my own question - Wondering what the differences are between LM4F120 / Tiva, and this board. :)
