Force Touch and Fingerprint Sensing – Different Solutions

The edge-to-edge, bezel-less viewing space of the Infinity Display means the precious real estate for a physical home key is no longer available. Here, Samsung did follow their two competitors by designing the Galaxy S8 and the Galaxy S8+ with force touch solutions, (3D touch, if you are an Apple fan). On both phones, the force touch is confined to a specific place, right where the physical home keys would have been located.
With both the Galaxy S8 and Galaxy S8+ in our labs, we were able to observe that, while the location was the same, the force touch solutions are different between the two phones. In the Galaxy S8, Samsung uses their own force touch component. The Galaxy S8+, however, employs an STMicroelectronics fingerprint and force touch sensing chip from the Finger Tip product family.
If there were any cost savings gained by not using a separate home key/fingerprint sensor assembly, the larger panel and more pixels of the Infinity Display have still resulted in higher costs. The Galaxy S8 costs are around 40% and 20% higher than the Galaxy S7 and Galaxy Note 7, respectively.

Baseband

The XMM7480 (PMB9948) modem die size is 7.70mm x 9.15mm (70.45mm2), bigger than the previous generation XMM7360 (PMB9943) which is 7.71mm x 8.47mm (65.30mm2).  Please contact TechInsights for the upcoming Intel XMM7480 (PMB9948) Modem Digital Functional Analysis Report (FAR-1709-803).

RF Transceiver



The Transceiver is new Intel Trx, the PMB5757.  After comparing the die photos of the Intel PMB5757 RF Transceiver to the previous PMB5750 used in the iPhone 7/7 Plus, it appears that Intel has re-used most of the previous chip. The two dies are in the same die size and they are almost identical except for minor changes in the left column and bottom row of repeated cells.

NFC Controller

We were not too surprised to find a NXP NFC module in the iPhone 8 Plus. This one has package markings ‘80V18’. This is different from the PN67V we found in the iPhone 7 Plus.

Wi-Fi/BT Module


Universal Scientific Industrial (USI) 339S00397 Wi-Fi/Bluetooth module.
the Broadcom BCM4361, and our analysis has confirmed that we are correct. Broadcom wins the wireless combo socket. 
TechInsights previously analyzed the Broadcom BCM4361 wireless combo SoC when we found it in our Samsung Galaxy S8 analyses.
BCM4361, TechInsights has also analyzed other Bluetooth 5.0 SoCs, including Texas Instruments CC2640R2F, Qualcomm WCN3990, and a dialog DA14586.  
TechInsights has completed Digital Functional Analysis on the  Broadcom BCM4361 (die BCM43570).

Audio ICs​ 

We see three 338S00295 Audio Amplifiers.  They should be from Apple/Cirrus Logic.  The 338S00248 is the Audio Codec from Apple/Cirrus Logic too.

USB Interface

A Cypress EZ-PD™ CCG2 USB Type-C Port Controller is found in the iPhone 8 Plus. We decoded the part number as CYPD2104. The chip enables fast charging for the iPhone when coupled with a compatible accessory Apple USB-C power adapter (29W Model A1540). We have already seen it in the iPad Pro 10.5 ‘’ in June 2017.



Apple iPhone 6 and iPhone 6 Plus

Qualcomm Gobi MDM9625M Baseband Processor


Qualcomm ដំណោះស្រាយ RF,   Baseband (Modem)សម្រាប់ទូរស័ព្ទ. 
Apple iPhone 6,  Qualcomm's Gobi Modem product line- the MDM9625M, with RF transceiver and RF receiver roles being supported by their WTR1625L and WFR1620 ICs respectively. The only other RF support we see from Qualcomm is with their power envelope tracking IC, the QFE1100. As for the other RF functions such as the RF antenna switches and power amplifiers, Apple once again uses multiple manufacturers like RFMD, Murata, Avago, and Skyworks. Based on our quick analysis, this is the same RF design strategy 

Apple A8 Processor


A Mobile Processorត្រូវបានរកឃើញនៅក្នុងកុំព្យូទ័រចល័តនិងទូរស័ព្ទចល័ត។
CPUត្រូវបានរចនាឡើងដូចកុំព្យូទ័រចល័តធម្មតាតែត្រូវបានបង្រួមអោយតូចដើម្បីវារត់ត្រជាក់វាប្រើថាមពលអគ្គិសនីទាបជាងសមាសភាគក្នុងរបស់វាហើយមានសមត្ថភាពដំណេកច្រើនជាង។

The A8 is smaller than predecessor A7, and also has an NXP LPC18B1 M8 motion co-processor just as the A7 was supported by an M7 co-processor.

The NFC Controller  (Near-field communication)




NFC គឺជាលក្ខណៈពិសេសមួយស្ទើរតែគ្រប់ទូរស័ព្ទទាំងអស់សព្វថ្ងៃនេះប៉ុន្តែតើអ្នកអាចធ្វើអ្វីបានជាមួយវា?


តើអ្នកធ្លាប់ឆ្ងល់ពីអ្វីដែលធ្វើឱ្យសេវាកម្មផ្ទេរនិងចូលដូចជា Apple Pay , Android Pay និង Amiibo ធ្វើការដែរឬទេ? តាមដែលវាហាក់ដូចជាសៀករហ័សកម្មចឹង។
ដូច្នេះតើវាពិតប្រាកដណាស់? ជាធម្មតាវាជាវិធីសាស្រ្តមួយនៃការផ្ទេរទិន្នន័យឥតខ្សែដែលហៅថា NFC (Near field communication) ដែលបានរកឃើញហើយបន្ទាប់មកវាអនុញ្ញាតឱ្យមានបច្ចេកវិទ្យានៅជិតគ្នាដើម្បីទាក់ទងដោយមិនចាំបាច់ភ្ជាប់អ៊ីនធឺណេត។ វាងាយស្រួល, លឿននិងធ្វើការដោយស្វ័យប្រវត្តិ។

The 6-Axis Accelerometer and Gyroscope


ទូរស័ព្ទ iPhone 6 accelerometer​ និង gyroscope មានតួរនាទីជួយបង្កើនល្បឿន។
ជាធម្មតា STMicroelectronics ទទួលបន្ទុកនេះ។  ពេលនេះInvenSense ទទួលបន្ទុកនេះ ។ 
6-axis accelerometer and gyroscope គឺឧបករណ៍ចាប់សញ្ញាអេឡិចត្រូនិកល្បឿនមានឈ្មោះថា​MP67B។ The MPU series 6-axis device interfacing with a standalone compass and the APU.

The eCompass (ត្រីវិស័យសម្រាប់ទូរស័ព្ទ iPhone)

យើងតែងបានឃើញ AKM8963 នៅក្នុងម៉ូដែលទូរស័ព្ទដូចជា Apple, Samsung, LG, Motorola, Huawei, ZTE និងឧបករណ៍ដទៃ។ 
សព្វថ្ងៃនេះ មិនមាន AKM នៅកន្លែងណាមួយនៅលើ PCB,
 ជំនួសវិញយើងបាយើងបានឃើញគ្រឿងអេឡិចត្រូនិក InvenSense ស៊េរី MPU7, Bosch Sensortec 2mm x 2mm ។ 
ដំបូងយើងគិតថានេះជា eCompass ប៉ុន្តែទំហំICនិងសញ្ញាសម្គាល់មិនស្របតាមឧបករណ៍ eCompass ស្តង់ដានៅលើគេហទំព័ររបស់ក្រុមហ៊ុន Bosch ដែលយើងបានឃើញពីមុនទេ។ 
ឥឡូវនេះយើងបានធ្វើការងារពិសោធន៍មួយចំនួនឧបករណ៍ Bosch នេះមើលទៅដូចជា BMA280 ដែលយើងបានឃើញនៅក្នុងទូរស័ព្ទរាប់សិបចឹង។
 យើងមានចម្ងល់ពីរយ៉ាងធំកើតឡើង:
1) តើត្រីវិស័យនៅទីណា? 
2) ហេតុអ្វីបានជាក្រុមហ៊ុន Apple មានកម្រិតស្ទង់ល្បឿនត្រីវិស័យពីរ? 
ចម្លើយគឺងាយទេពួកគេនឹងមិនធ្វើដូច្នោះទេ។ 
បញ្ជាក់បម្ថែម: AKM គាំទ្រ  eCompass នៅក្នុងទូរស័ព្ទ iPhone របស់ក្រុមហ៊ុន Apple អស់រយៈពេលជាច្រើនជំនាន់មកហើយ។ 

Camera Enhancement


Apple has not increased the camera size in their iPhones since the iPhone 4S. Instead, Apple decided to keep the same size 8MP rear camera for both devices with some additional camera enhancements. With the iPhone 6 Plus, they also added optical image stabilization (OIS).
