I knew about the first bit.

But not the second.

Wait to learn if coprocessor is digital hub or is motion processor including MEMS

@Peter:

I work for Chipworks - we'll be pulling apart the M7 motion chip when we tear down the phone.

>> But anyone can get hold of a piece of the company by buying the publicly traded shares.

We have not seen that a lot in the electronics industry - buying the whole company. I do believe though that will happen. The margin for mistake is so low now that many players will exit in coming years. Technology has enabled faster disruption and that is bad news for the incumbents

MEMS wil eventually lead to the evolution and revolution everyone has been waiting for.  There are so many good opportunities in MEMS that any serious player will not pass away. However, MEMS is very challenging. It is not a business of the faint in heart. You need to be tough to design and succeed in it.

Given that Dialog is already an established supplier to Apple, that raises the intriguing possibility that the M7 motion coprocessor announced this week could be Dialog-based, with an ST(?) MEMS co-packaged. ST could handle the packaging side since they already stack MEMS on ASICs.

We'll see next week!

@Peter, thanks for the clarification. I imagine products like that would be much needed, but you are right -- who are going to fabricate those?

@junko

Must stress, as Jalal Bagherli did to me, that the SiTime/Dialog work is under a research partnership.

It may or may not go further.

There are definitely issues over moving tiny MEMS components around and bonding them to larger die and achieving good yield.

Both SiTime and Dialog are fabless so who is going to take responsibility for that vital part of the test/assembly/packaging if it should ever go further?

Not that I know of

Instead it tends to be companies like InvenSense  ST that are packaging multiple MEMS, analog and CMOS die in one motion processor component, which may have pins to also take external accel, gyro or barometric inputs.

Others such as PNI Sensor and even Apple are producing digital motion processors that simply off load the sensor fusion work from the application processor. such DMPs have to be connected to the sensors as a hub. The risk for PNI (but not for Apple) is that the coprocessor being digital could simply get integrated out of existence in the next generation of application processor.

The third approach taken by some companies is to assert that their value-add is in the software and algorithms that turn raw data into the "opinion" that somebody just picked up the phone and the display should be switched on. The problem for them is ambiguity over who they are selling to, who makes the software decision

However, Dialog and others that already sell chips into mobile motherboards are in the position that they already have an analog, mixed-signal, HV die there and they can "sweep up" other functons (audio, LED driving, and so on) as they come into existence.

@Peter, are there any other companies "integrating timing MEMS and PMIC" like Dialog and SiTime?
