With the emergence of IPhone 5, Apple's Lightning latest interface standard has followed. This standard may become an interface specification that Apple has invested for a long time, and its life expectancy may be as long as 10 years.
According to the research on the cost of each component of IPhone 5, Lightning's ASP index (average selling price) is a part of the cost increase of new equipment compared with IPhone 4S.
After all, Lightning is a new specification and new technology to replace the 30-pin interface that has been launched for nearly 10 years since the IPod period, a big turning point.
The Lightning interface specification is similar in size to the regular MicroUSB, but Kuo said that Lightning has a higher manufacturing threshold and higher technical standards.
In terms of the work distribution of the pins, 4 contacts are used for data transmission, 2 are for accessories, and 1 pin is used for charging 1 pin for grounding.
Among them, the data transmission has 2 pins may be a redundancy strategy, for future data transmission, such as compatibility with future USB 3.0 or Thunderbolt. Of course, this is just a guess
The life of the Lightning interface may be 5 to 10 years. The growth of ASP should be only the first two years of production equipment. With the deepening of the cooperation between Apple and partners and the collection of patent fees, the cost of the new interface should be well controlled. It is said that Apple will use Texas Instruments' chips for product certification in the future. Third-party manufacturers will find it difficult to manufacture or sell Lightning-compatible devices if they do not support the related licensing fees.
IPhone5's LighnTIng connector is significantly smaller than the 30po connector used by IPhone4, 4s, etc. About 1/4 of the old connector.
In addition, the Lightning interface has no directionality, and plugging and unplugging is more convenient.
The following picture is a disassembled picture of the LighnTIng interface, but we don't have the pin definition of the LighnTIng interface, but we can definitely have two roots for power supply and grounding. Others guess it. According to Apple, this is a pure Digital interface, but they also claim that IPhone5 supports analog audio and VGA signal output.
