MSP430F5435A and CC2560 in the remote control of the new Amazon Fire TV http://www.ifixit.com/Teardown/Amazon+Fire+TV+Teardown/23856#s61356

Apple G5 PowerMac (PCI version, circa 2004)     There where also several other TI chips for power management and firewire on the huge motherboard.

Philips Hue Tap, a wireless light switch without battery, featuring a MSP430FR5730   Teardown by Adafruit, with the MSP430 discovered at the 15 minute mark. https://youtu.be/4T4nhuobjZM?t=875

Ah, love these kind of threads! Anonymous Teardown Addicts anyone? :smile:

 

Jawbone UP Pedometer uses a MSP430F5548, as seen on EEVBlog: (7:30)

Interestingly the fancier Nike+ Fuelband also contains a MSP430F5528, but seems to be dedicated to Bluetooth communication: (13:27)

Talking about EEVBlog, today's teardown, the Fluke CNX3000 multimeter and wireless accessories featuring a whole bunch of MSP430's:


M430F5435A in the main unit (7:30), M430F47163 (25:26) in the first slave unit and presumably the others too. Using a CC2530F128 for communications.

That's a cool IR transmitter. Reading the report (I think this is a school project) you can see it's quite out-dated; the references name nothing more recent than 2002.

If I'd build a similar thing nowadays there are some things I'd do different and make it significantly cheaper. First he's using the MSP430F1101A, which goes at $1.06, while an MSP430G2001 would do the thrick too and goes at $0.34.

Second, the more recent MSP430 support pull-up to be configured in I/O lines, so that saves us 5 resistors (and reduces component placing to single sided, this saves a lot of money in real production).

The 10-pin 0.5mm pitch zif socket (ouch, pricey!) for JTAG can be replaced by a 0.05" pitch quartet of holes, allowing programming with spy-bi-wire.

For some reason he uses a FET to power his LED, I don't think that's necessary at all.

He uses 2x 1uF + 10nF power decoupling on a battery, I think a single capacitor would do the trick at well. (but we need another 2.2nF capacitor on RST).

He estimates his fobs at a price of about $21,- of which $11,- are for PCB manufacturing, at current prices you could easily go to $3,-, then $2,- for the casing, fine with me, and the components would go at.... well.... the battery and battery clip, plus a few cents. I think a "remake" would go for under 7$, cutting the price in three!

Two of the three latest "fitness" devices have been mentioned above, Jawbone Up and Nike Fuelband. Here is the third one, Fitbit Ultra using F5419A.

Unfortunately the MSP430 has been replaced by a STM32L in there latest products Fitbit One and Zip.

The Jawbone UP is a shambolic piece of work.  After seeing the teardown, I would never buy one.  Nike Fuelband also uses MSP430, though, so it's nothing against the 430.

 

Nike has a long history with the MSP430.  The Nike Fit / Nike Plus widgets have used MSP430 since the beginning.  That alone is probably more volume than AVR has, total.

 

STM32L is cheaper than the MSP430 parts of similar spec, which is most likely the reason why it got selected.  I am also using STM32L151C8 in a product.  It is a great MCU, I must say.  I still love the CC430, though.
