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?

impact of 64 bit

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.

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.

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 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.

Andriod devices have similar devices as Sensorhubs

NO RATINGS
Andriod Devices such as Samsung S4 already have similar devices in them by companies such as Atmel

http://ir.atmel.com/releasedetail.cfm?ReleaseID=764171

 

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.

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.

Best

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

Nice point, Chipmonk. Chipworks: Hope you heard this!

@Tom - How did you determine that the NXP device shown is an LPC18xx device?

The A7 is about 10mm x 10 mm.  About 4 of the LPC18A1s fit along one A7 edge.  That means the device is about 2.5 mm x 2.5mm.  If you look at the ball count, it is 5 x 6 with a 0.35mm pitch which is about 2.5 mm x 2.5 mm.  A quick look at the datasheet shows the smallest LPC18xx is 100 balls with about 0.8mm pitch--nearly the same size as the A7.  Clearly the device shown on the board is not nearly the same size as the A7--maybe 5% the area!

The math doesn't add up.  Are you sure LPC18 and LPC18A1 = LPC18xx?
