Internal device connector Lightning in iPhone 5

As with most of the functions of the iPhone 5, the new smaller connector Lightning was known even before the official presentation of the smartphone. True, the blurry picture was hard to understand the new interface - it's not just a compact version of the traditional 30-pin port Apple. The new cable-sided, and a new feature that will add a company that will pay users.

Connector Lightning - an 8-pin standard, but each cable - 16 pin. Thus, as if you did not connect it to the iPhone 5, you get the first time. How is it, told in detail in the publication PCWeek, and it appears that everything is much more complicated than it seems at first glance.

On each side of the Lightning - contacts, numbered from 1 to 8. By checking the experts found that the first top port provides power via USB, and the connectors are symmetrical, that is, the eighth performs the same function. So, if you turn the plug, the contact for the supply will still be in place.

Contact data, however, are quite different, they are asymmetric. That is, if you turn the connector, then they would not be in those places where it is necessary. For example, if you look at the second bottom "pin" for the data, it is electrically connected to the second from the top. So, when you turn the plug, cable ends connect with the wrong contacts smartphone.

Experts attribute this strange circumstance as follows: iPhone 5 dynamically assigns the function "pins" with a special chip inside the phone. Apple said that the connector Lightning uses only the contacts that are needed for specific applications, and accessories. iPhone 5, apparently checks the type of transmitted data and change settings on the fly.

As a result of all this, you can connect the Lightning as you want, and this connector has room for growth in the future. But the complexity of the interface can be explained by the authentication chip inside the cable. It is located on a wire V +, so that without it the cable will not work.

If you think you can easily get a cable from Apple, you need, then you are wrong. Companies do not have enough cable Lightning, and most likely due to the fact that produced them are scarce. Not only because of the difficulties in manufacturing, but also because the cost is much higher than the old 30-pin version. Analysts estimate the cost of Lightning in 3.5 dollars, which is 775% more than the traditional 30-pin cable.

TSMC will be the supplier for the quad-core Apple

Analysts have long tried to link the interests of Apple and Taiwanese contract chipmaker TSMC. California company is clearly not going to stop the prosecution of Samsung that not only competes with it in the segment of smartphones and tablets, but it is also a supplier of flash drives, processors and other components for the most similar products Apple. Continue the "war" in this state, would be tantamount to purchase ammunition from the enemy.

The research firm Citigroup Global Markets said that TSMC will be the sole supplier of 20-nanometer chips for a new generation of Apple in the next one or two years. According to observers, the U.S. consumer electronics giant has decided to use their new products quad 20-nanometer processors, and TSMC has made good progress in the development of these advanced standards.

Judge JT Su said that Apple began testing the 20-nm process technology TSMC in August of this year, and in November, may issue a pilot batch of processors. Mass printing chips could begin in late 2013 - as a result of significantly increasing the chances that TSMC will increase the cost of capital for the development of capacity to $ 11-12 billion in 2013 and 2014.

Analysts suggest that Apple develops its own quad-core ARM-processors are not just for the Tablet PC iPad, but also for TV iTV, which goes so many rumors, and even for a new series of laptops MacBook. Chips for smartphones iPhone, he predicted, with the transition to the 20-nm dual-core remain to improve energy efficiency.
