Apple iPhone SE Teardown, Production Provide Chain,
Contributed by way of Jim Morrison, Ray Fontaine, Dick James, Daniel Yang, and Mandi Gingerich
The long-rumored, cost-friendly iPhone SE used to be in any case introduced on March 21st of this 12 months. Stated to be the iPhone 6s squeezed into the smaller iPhone 5s frame, this new iPhone options an interesting worth level with flagship-level efficiency. Some right here have even likened it to an previous Chevy geared up with a peppy new Corvette engine. Early critiques of the iPhone SE had been relatively certain; maximum appear to agree that the 4-inch iPhone packs some tough internals. We were given our arms on an early iPhone SE and shall be taking a more in-depth take a look at the ones internals to decide how a lot innovation used to be packed in between the acquainted matte chamfered edges of the iPhone SE.
Let’s start with our preliminary teardown pictures. Whilst the outdoor does glance similar to the iPhone 5s, with only some new touches, at Chipworks, in fact it’s what’s at the within that actually counts. Under you are going to see the again of the PCB that can fortify the tough new mixture of internals.
And the entrance of the PCB:
A9 Utility Processor
First up, the promised A9 does certainly seem to be the similar flagship processor discovered within the iPhone 6s. Our pattern bears the APL1022 phase quantity, indicating that it originated in a TSMC facility. The 1604 date code tells the story of this little chip’s adventure the entire means out of the packaging space, onto the motherboard, and into the telephone and our arms in simply nine weeks, a real credit score to Tim Prepare dinner’s famend experience for provide chain control.
Accompanying our flagship processor on its adventure is a SK Hynix reminiscence, most likely the similar 2 GB LPDDR4 cell DRAM discovered within the iPhone 6s. The date codes may in reality inform a tale: the decapped utility processor chip is dated 1535, Aug/Sep ultimate 12 months, so it used to be sitting in stock for some time; the reminiscence is 1549, ultimate December; and probably the entire package-on-package used to be assembled this 12 months on the finish of January.
Does this replicate the rumored loss of gross sales for the iPhone 6s collection, and used to be that the motive force for the usage of the A9 within the SE? We imagine best Tim Prepare dinner can resolution that.
Toshiba will get the nod for the 16 GB of flash, and our chip-nerd antennae let us know it is made of their previous, and probably less expensive, 19 nm procedure (they’re now transport 15 nm portions).
Contact Display Controller Resolution
It is a flashback to 2018. Right here we see the Broadcom BCM5976 and Texas Tools 343S0645 that have been extensively utilized again within the iPhone 5s. The BCM resolution has been utilized in the whole lot from iPods and iPhones, to the MacBook Professional, MacBook Air, and iPad Mini.
Riding the NFC is the NXP 66V10. The 66V10 accommodates two die, the Safe Component 008 and the NXP PN549. The 66V10 first gave the impression on Chipworks’ radar in September of ultimate 12 months within the iPhone 6s.
6-Axis Inertial Sensor
The 6-axis inertial sensor (x, y, z, roll, pitch, and yaw) is an InvenSense 6-axis sensor comprised of two die, the ASIC and the MEMS sensor. This too used to be first noticed by way of Chipworks within the iPhone 6s.
Different iPhone 6s Throwbacks
Additionally a throwback to the iPhone 6/6 Plus is the Qualcomm MDM9625M modem and the WTR1625L RF transceiver subsequent to it.
The Audio ICs are nonetheless the similar 338S00105 and 338S1285 units used within the iPhone 6s and 6s Plus. Chipworks thinks that they’re Cirrus Common sense designed units.
OK. So What is New?
After all, Chipworks did see one thing new within the iPhone SE: a 338S00170 tool, which could be very most likely a brand new Apple/Conversation energy control IC.
Whilst there may be nonetheless a lot to find about this new iPhone, what’s turning into transparent is that this isn’t your conventional Apple unlock. There are only a few new portions, however that barely approach there’s no innovation. As is the genius of Apple and its fearless chief, Mr. Prepare dinner, it’s the mixture of the entire correct portions that make a a success product. Discovering that just-right steadiness of previous and new, and at any such low charge, isn’t any simple feat.
There are a number of elements within the iPhone SE that we’ve got noticed earlier than. There also are some elements we have now by no means noticed earlier than. Those new units come with a Skyworks SKY77611 energy amplifier module, a Texas Tools 338S00170 energy control IC, the Toshiba THGBX5G7D2KLDXG NAND flash, an EPCOS D5255 antenna transfer module, and an AAC Applied sciences 0DALM1 microphone. To know what’s within those units we will be able to wish to do a little deprocessing to inspect the silicon within. Keep tuned for updates whilst our lab does what they achieve this neatly.
