How to Work Lightning Cable & Connectors?
We couldn't assist but notice that there is a great deal of supposition and discussion (and frankly, a few wild guesses) concerning the features of Apple's new lightning Cable & Connectors. We don't normally provide (a total amount of five blog sites!) this much attention to a single electronic devices teardown, yet since we haven't seen it elsewhere yet, we figured the globe needed "just one more thing" on the Apple iPhone 5. We have validated that the Lightning Cables does have four chips embedded in it, plus some passive devices. 2 of these chips are very straightforward (only several transistors), and the third is an NXP NX20P3. Nonetheless, the fourth and perhaps most interesting of these is the TI chip.

The side image reveals the location of the TI chip on the Lightning Cables. As soon as we stripped away the wire real estate (much easier said than done) and took the die out of the plan, we found pass away markings. (See our die image listed below). This part number is not published by TI.
Nonetheless, all four do have some common features. All use a single cord SDQ user interface (TI's proprietary serial interactions procedure). So, it is definitely most likely that the does have some safety and security implemented on it. It would certainly likewise promise that it consists of an SDQ user interface.
We continued our laboratory deals with them and also currently have a reduced steel example to see (and also acquisition in the RontechUSA . On this example, we have had the ability to see some further details of this chip. There is an electronic reasoning block occupying the leading left part of the chip. This block consists of regarding 5K gates of reasoning. Also on the chip, with most likely 64 or 128 little bits of storage space (visual assessment just, complete RE not finished). There are likewise some big chauffeur transistors, a fair bit of analog wiring, and a fair quantity of capacitance. This is absolutely all constant with a serial interaction chip consisting of some straightforward safety attributes.
Three other chips on the lightning port board
To complete the story, allow's look at the various other three chips on the lightning adapter board & Lightning Cables. Consists of one substantial transistor occupying over 75% of the die area. It additionally has a fair quantity of analog wiring, as would be consistent with their line of charging gadgets for peripherals-- from our last journey to the Applied Power Electronics Seminar we know that this is a market that is very strong in. The last two passes away appear to be basic power transistors. Excellent layout wins once more for TI.
