2x2mm 10uA current 3-AXIS mems sensor

I still can not belive it DK has the VTI "CONFIDENTIAL" datasheet online, get it here

$15 price range is not cheap. Are you able to get better pricing with volume?

The other downside is the BGA packaging. That will make integration into prototypes more difficult for those of us still building boards by hand soldering.

Someone needs to market a small stamped lead frame for packages like this. You would lay the chip on its back and solder the individual leads to the BGA solder balls (or contacts on a QFN package). You would then either snip the lead frame or remove the adhesive backing and solder the leads down to the pads on your PCB.

we are going to supply adapter PCBs soon probably before the ICs become available :)

the BGA8 is actually not hard to solder to correctly designed land if you read our NOV issue there is a picture of CMA3000 soldered to simple break out board

funnily, not only Digikey has LEAKED the NDA only datasheets but also one russian company

they even have some example C code examples online :)

i uploaded a picture of working prototype with cma3000

this is shot of very first test, the c program overwrites screen without clearing background so the numbers look bad

The new Analog devices ADXL345 is somewhat similar (25uA instead of

I can't find the ST version, do you have a link?

thanks

Nice IC.

I like the idea using a Nintendo DS for implementing a SPI test hardware. Is there any simpler method of hacking this console than buying an old cartdrige and overwriting the EEPROM?

dont be lazy

Antti PS at electronica ADI/ST/Freescale all promised new 3 axis sensors before/at end of 2008

ST is now out, it seems ADI, need check freescale, they should also have new stuff

Hi Frannk

the SPI interface is done with this board

the CPLD is inslot programmable using DS version of Xilinx XSVF player :)

hum.. you seem to be well informed? There are 5 DS roms known that have know STACK overflow exploits found that allows the game state eeprom to be written with special code that is executed after being loaded.

but those are not old games :) you cant just go and buy any old game it is of no use! For making the slot2 adapters, then well 1.6mm thick PCB is all you need

I find the DS the easiest gadget to use, the CPLD board is SO easy to use and reprogram - no need to fight with impact :)

and the C library support is superiour, really easy to write hardware related stuff.

much more easier than it was in the old days when PCs used to have LPT ports!

Oh, the 331 I know about that one, it's 250uA in normal mode. no real power saving there, I was hoping you were referring to a newer model

Nice.

Yes, the concept is the same for many game consoles. Some time ago I've started the Lua Player project for the PSP and the security for the very first PSPs was nearly no security at all, which made it easy to just copy the programs to the memory stick with the integrated USB port from a PC.

You are right, I think there is no cheaper development kit for this price with audio IO, two color screens, where one is a touch screen, USB, WLAN, two CPUs, integrated rechargeable battery etc. Maybe I'll try to do some stuff for it when I have more time. Too bad that Nintendo locked it, so you have to hack it.

it is now released and all datasheet are freely downloadable

Nice, documented very well too, take note of the errata though. Anyone know why the analog only device takes more power then the digital? I can't figure that out.
