Sounds you know much more about gyros than me @SiliconAsia...I run R&D conference (www.cmoset.com) where many MEMs devices are discussed so hence my impression that many devices are available...but that could be low volume, high end application or just early prototype...like in every other market 2-3 players command most of the market share, no surprise here...I was just curious why Invensense is in that group, there must be something in the underlying technology (performance, cost etc) that put them in that group...Kris
You said there are many MEMS gyros - Can you list them? Only ones I know are 1) ST and 2)Invensense. Others are not in real production or only aiming at high end? You may mean many are trying but not many are in real volume production. The "volume" is the key word here. Having volume production capability or know-hows is a HUGE differentiator in MEMS.
There are not so many suppliers of six-axis combo gyro and accelerometers, with local logic processing..which InvenSense calls a motion processing unit.
It may well be that InvenSense is not better or cheaper than the competition but they did get and held on to the design win in the Ninetendo Wii.
