Other Parts Discussed in Thread: MSP430FR5949, MSP430WARE, MSP430FR5969

Hi,

I need a very low power experimental platform for WSN

I saw this http://www.ti.com/ww/en/techdays/2012/docs/toronto_abstracts.pdf  

(see Track 5) - is this real?

How far away is the evaluation board and a sample silicon for wolverine?

    I don't know whether Wolverine is available yet. However, the MSP430FR57xx uses mostly the same technology (FRAM), just with less memory. And there's an experimenters board available too.
    Also, it highly depends on your applicaiton whether Wolverine is the device with the lowest possible power usage. For some jobs, the normal MSPs can be even less power-consuming. (e.g. in a remote that is powered by a button press, doesn't know what happened before, and cuts its power off when done, you don't need a Wolverine at all, and running from a flash-based MSP may be more efficient.

    Wolverine excels if your applicaiton has to constantly store non-volatile data but is powered-off (or in extreme low-power mode) in the meantime. When you need short bursts (or longer ones) of maximum computation power, then the Wolverine won't be your best choice (as the max speed of FRAM actually limits the processing power)

    Thanks Michael for your thoughts.

    I was hoping for a feedback from people, who actually attended the Technology Days, saw the device in action and read documentation.

    And I hope, there will be some improvement compare to current FRAM devices.

    Regards

    I'd like to see a hybrid where the usual info flash is replaced by (some more) FRAM, but the application itself still runs in flash. It would come closer to the (more expensive and still slow, but easier to handle) EEPROMs in other MCUs (or more exactly: would be superior).

    Hello again,

    Does anyone know if there is a preliminary specification for MSP430FR5949 available?

    If yes, where to find one?

    Is there a pin/modules compatibility between wolverine and other MSP430 devices?

    Header files appeared a long time ago. More RAM and FRAM, few other changes. Pinout not shown, but should fit the current package.

    Yes, there are already examples of coding within MSP430ware under CCS,

    so it gives an idea what's inside, but no other info (like pinout)

    (The "coming soon" banner hasn't change for a while)

    For example for MSP430FR5949 what existing device pinout might be the same?

    After examining the peripherals in FR5949 and FR5969, I do not see any reason they need to use a package that is different from FR57xx. (That is, 40-pin RHA or 38-pin DA are sufficient.)

    Prelliminary documentation for the MSP430FR5949 is available now.  Samples of the superset MSP430FR5969 are also available. MSP-FET430U48C is the first kit you can use with these samples.

    Any idea how long it will be before the FR58xx/FR59xx controllers are available for purchase?
