InvenSense still not in the Watch -2
Chipworks is out with a Series 2 Watch tear-down
and it reveals that the motion sensing chip is from STMicro and
the microphone from Knowles. Apple should have been designing
InvenSense parts into the device by this time if the relationship
is growing. Without that, it's probably just a matter of time
until iPhone gyros are second-sourced or replaced entirely. That
would be a crippling blow for InvenSense.
