iPhone 5s Teardown

Teardown of iPhone 5s by iFixit is below. Key IC in the latest Apple smart phone are:

• Murata 339S0205 Wi-Fi module (based on the Broadcom BCM4334, according to Chipworks)
• SK Hynix H2JTDG8UD3MBR 128 Gb (16 GB) NAND Flash
• Qualcomm PM8018 RF power management IC
• TriQuint TQM6M6224
• Apple 338S1216
• Broadcom BCM5976 touchscreen controller
• Texas Instruments 37C64G1
• Skyworks 77810
• Skyworks 77355
• Avago A790720, A7900
• Apple 338S120L
• Apple A7 APL0698 SoC (based on this MacRumors post, the markings F8164A1PD indicate the RAM is likely 1GB), was fabbed in July.
• Qualcomm MDM9615M LTE Modem,  WTR1605L LTE/HSPA+/CDMA2K/TDSCDMA/EDGE/GPS transceiver.

• Along with the fingerprint sensor, the A7 is a major enticement for consumers to pick the 5s over the 5c.
• The A7 is advertised as providing twice the performance of the 5 (and 5c)'s A6 processor.
  • The switch to the A7 marks the first use of a 64-bit processor in a smartphone. Based on AnandTech's review, it seems that the bulk of the A7's performance gains do not come from any advantages inherent to a 64-bit architecture, but rather from the switch from the outdated ARMv7 instruction set to the newly-designed ARMv8.
  • The modern ARMv8 instruction set was designed for a 64-bit architecture. It does away with the legacy support of the last 20 years, which increases efficiency, improving performance without sacrificing battery life.

 iPhone 5s Teardown

Teardown
Teardowns provide a look inside a device and should not be used as disassembly instructions.

Featured Guide
This guide has been found to be exceptionally cool by the iFixit staff.
One…Three…G…Three…G again…S!…Four…Four again!…And another S!… Five!…S!...Five?!…C!
Thankfully Apple is in the technology business, not the education business. We can only imagine how jumbled pre-school students' ABCs and 123s would be if they were taught in Cupertino.
Crazy nomenclature aside, we were anxious to bite into this latest piece of phone fruit. So anxious, in fact, that we sent one of our own to the land down-under to get one.
Join us as we dissect the latest iPhone; otherwise:

EditStep 1 — iPhone 5s Teardown 
• An iPhone release means a trip to the future—the iFixit teardown crew has traveled 17 hours forward in time to get the iPhone 5s early.
• We want to send out a big thanks to our good friends at MacFixit Australia for letting us use their office in Melbourne for the teardown. They stock Mac and iPhone upgrades/accessories, and also carry ouriFixit toolkits.
  • To cover all our bases, we confirmed with our best linguists that the 5s upside-down is still the 5s.
• Speaking of toolkits, for this teardown, we'll be using iFixit's brand-new Pro Tech Screwdriver Set.


1 EditStep 2 
• As we ready ourselves to delve into the delightful innards of the 5s, let's check out some of its tech specs:
  • Apple A7 processor with 64-bit architecture
  • M7 motion co-processor
  • 16, 32, or 64 GB Storage
  • 4-inch retina display with 326 ppi
  • 8 MP iSight camera (with larger 1.5µ pixels) and a 1.2MP FaceTime camera.
  • Fingerprint identity sensor built into the home button
.........



1 EditStep 12 
• Looks like we found a Murata 339S0205 Wi-Fi module (based on the Broadcom BCM4334, according to Chipworks).
• Again comparing our 16 and 64 GB models:
  • It seems that the Murata IC is the same between both iPhone 5s'.
  • The design of both logic boards may be identical, but slight differences in markings (e.g. 94V-0 on the rightmost, nonexistent on the leftmost) may indicate that Apple is manufacturing the 5s logic boards at multiple locations.

1 EditStep 13 
• Open ses-EMI! Behold, IC treasures identified:
  • SK Hynix H2JTDG8UD3MBR 128 Gb (16 GB) NAND Flash
  • Qualcomm PM8018 RF power management IC
  • TriQuint TQM6M6224
  • Apple 338S1216
  • Broadcom BCM5976 touchscreen controller
  • Texas Instruments 37C64G1
  • Skyworks 77810

5 EditStep 14 
• More ICs!
  • Skyworks 77355
  • Avago A790720
  • Avago A7900
  • Apple 338S120L
• A super-awesome thanks to the Chipworks team for helping us decode and discern these delightful devices!

3 EditStep 15 
• Turning our attention to the backside of the logic board:
  • Apple A7 APL0698 SoC (based on thisMacRumors post, the markings F8164A1PD indicate the RAM is likely 1GB)
  • Qualcomm MDM9615M LTE Modem
  • Qualcomm WTR1605LLTE/HSPA+/CDMA2K/TDSCDMA/EDGE/GPS transceiver.
• As we search for a much-anticipated M7 coprocessor, we begin to wonder if it actually is a separate IC, or if it is additional functionality built into the A7.
  • Maybe the "M" stands for "magical," the M7 is invisible, and Apple does use pixie dust to hold the device together. Or perhaps the "M" stands for "marketing"…
• Our A7 was fabbed in July.



3 EditStep 16 
• It's time to investigate the new kid on the block, and it's fly like an A7. Along with the fingerprint sensor, the A7 is a major enticement for consumers to pick the 5s over the 5c.
• The A7 is advertised as providing twice the performance of the 5 (and 5c)'s A6 processor.
  • The switch to the A7 marks the first use of a 64-bit processor in a smartphone. Based on AnandTech's review, it seems that the bulk of the A7's performance gains do not come from any advantages inherent to a 64-bit architecture, but rather from the switch from the outdated ARMv7 instruction set to the newly-designed ARMv8.
  • The modern ARMv8 instruction set was designed for a 64-bit architecture. It does away with the legacy support of the last 20 years, which increases efficiency, improving performance without sacrificing battery life.
• We'll have to wait until we get inside the chip to find out who manufactured it.
