So a few of us spotted the EnergyTrace press release from TI, but what's also noteworthy here is that Wolverine has now gone to production--no more XMS430 type of silicon at least for the FR59xx series, and more importantly a wider variety of chips & packages are now becoming available.
Priya's post indicates as such: http://e2e.ti.com/support/microcontrollers/msp430/f/166/t/350727.aspx
I just ordered 2 samples of the MSP430FR5949 - in DA package (TSSOP-38, 0.65mm pitch, similar to the MSP430F5172 and MSP430G2955 TSSOP variants). http://www.ti.com/product/msp430fr5949
There's an interesting white paper I found regarding the Wolverine series: http://www.ti.com/lit/slay031
This refers to the Extended Scan Interface (ESI) found on some Wolverine chips. From what I can tell, none of the currently produced FR59xx series chips include this; TI's header files from the RH GCC install in CCSv6 imply that a later generation of Wolverine in the FR598x and FR588x series will come with this.
However, TI has released one of the FR69xx series chips into PREVIEW (XMS430 experimental silicon) with LCD driver; and this one happens to also include the ESI peripheral. See the http://www.ti.com/product/MSP430FR6989 for details... sample part listed as XMS430FR6989.
I'll be looking forward to seeing the Wolverine parts available generally from the distributors and I'm quite curious 1. how much markup there will be in price, and 2. whether distributors will stock the TSSOP packages or not. I sincerely hope so (I was quite disappointed with the MSP430G2955; only Digikey had the TSSOP version, and that I think was from an odd order since it still considers it a "non-stock" item).
