@ Roadman: Yeah it sounds like there was some heavy Apple marketing around this "custom M7." Not the first time there has been head spin!

Hi Tom,

Thanks for your efforts!

I'd encourage you to post here little nuggests that come up over the weekeend and send Susan Rambo and I at eet.com fuller dispatches as they emerge.

Andriod devices have similar devices as Sensorhubs
Roadman0   9/21/2013 4:26:03 AM
Andriod Devices such as Samsung S4 already have similar devices in them by companies such as Atmel



Other products such as MotoX have it too.  In short this concept of having sensor Hub has been around, it is just not publized like Apple did.  I suppose this what one gets for inovation these days.

It is hard to tell your best customer to get lost when you make a lot of money from their business.  The relationship will continue as long as it is in the best interests of both companies.

It's not such a mystery when you consider how much money they each make from that customer-vendor relationship. If the relationship were to suddenly end, both companies would suffer.

It is simply a mystery how Apple and Samsung could be competitors and best of customers. You have Samsung make A7 chip which is there to knock-out Samsung products in the market. A unique case for business schools.

impact of 64 bit
chipmonk0   9/20/2013 5:40:51 PM
Noticed denser interconnects in the A7, perhaps to accommodate the 2x wider ( 64 bit ) data and address buses within more or less the same real estate. Chipworks could go back and take one more look at their teardown of the Exynos 5 ( 32 bit 8 core ) in the Samsung S4 phone and compare the interconnect w/ the A7 ( both 28 nm by Sam ). Performance can actually take a hit if interconnect conductors & dielectrics are shrunk too much since resistance & capacitance will go up and will become a larger factor as the transistors get faster & more efficient.

I see iFixit says the fingerprint sensor is a Touch ID chip from Authentec which Apple acquired.

Any surprises in the data that's now dribbling out?

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
