TI MSP430 Wolverine now in production


Recommended Posts

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).

I already made 2 boards, one with MSP40FR5949 and another with MSP430FR5959, for testing my flasher. Both TSOP (DA) packages have same pinout as older MSP430FR5739, except there is no external vcore cap.

Is there actually any benefit from having production silicon? I mean I know that the XMS parts are only available through TI samples. I have one in the watch I'm developing.

 

But have they released an errata for the production 5969's is it any different to the XMS's errata.

 

Hi @@greeeg,

 

Basically, XMS silicon isn't signed off on for use in mass production of end products - you should only use XMS as samples for designing your product, etc, and use production silicon to actually produce any large number of units of a product for public consumption. In addition, the XMS silicon doesn't always have all of the calibration constants in the TLV that are in the production silicon - for example, temperature sensor calibration at 85C might be missing because that clearly requires testing going through a temp chamber and that may not be done for simply these XMS engineering samples. Finally, depending on the part the first production silicon may be a different revision than some or all of the XMS parts released meaning they may have different errata fixed - always check the revision letter.

 

In any case, once production silicon is out, it's always best to use that if you are making any sort of end-product, as it should be meeting all datasheet specs and is considered production quality.

 

Regards,

Katie
