MOBILE PHONES AREA

We first introduced the iPhone 4, Apple CEO Steve Jobs promised that if the latest smartphone has faster performance, better graphics, better graphics, a camera with higher pixels, and additional features compared to its predecessor smartphone. Behind the update is of course there are hardware components that support it.

Two technology sites, iFixit and Chipworks, managed to uncover the secret of the iPhone components 4 after doing reverse engineering to dismantle the device on each part.

4 revealed that the iPhone using Apple processor A4 as used on the iPad has a clock speed of 1 GHz. This is the first iPhone because the iPhone uses A4 3GS using S5PC100 Samsung processor 600 MHz ARM A8. A4 processor Apple uses ARM Cortex A8 cores. Because Apple does not manufacture their own hardware, Apple is likely to continue making progress to Samsung as it had done previously.

RAM Memory Capacity iPhone 4 of 512 MB or twice the memory and the iPhone iPad 3GS. When the prototype iPhone 4 leaked some time ago, reported its memory capacity is only 256 MB. With these facts, the possibility of Apple's decision to increase the memory capacity before production begins. Samsung-made chips used.

As a storage media, flash memory used in Samsung-made as well, namely Samsung K9PFG08. During this Samsung is known for its king partially flash memory. iPhone 4 provides two options with a capacity of 16 GB and 32 GB. PowerVR SGX graphics chips supported 3D Graphics Core 535.

Component which is the next scrutiny for touch screen controllers. Apple uses chips made by Texas Instruments are also skilled in this field. Apple to follow the evolution of the touch screen controller from the first generation that uses a solution with five chips, with three second-generation chip, and the latest generation only with a chip that is all in one type 343SO499.

Furthermore, the camera used. iPhone uses four 5-megapixel camera which can record 720p HD quality video and 30 FPS, better than the iPhone using the 3.2 MP 3GS. They say the camera systems and sensors used are from Omnivision though Chipworks can not ensure the details. Mengumumkna Apple already uses technology that camera BSI (backside Illumination) that maximize each pixel mendaptkan light enough to produce the best image. Omnivision known reliable in this technology compared to 20 companies of other sensors.

For a motion sensor that makes your iPhone into an intuitive tool for gaming and other navigation supported solution from STMicroelectronics. iPhone 4 using three-axis accelerometer sensor of the chip companies. These sensors support the system of MEMS (microelectromechanical systems) to menerjemhkan each movement into an electrical signal with a high level of sensitivity and accuracy.

No less important is the components to support communication access. iPhone 4 using chips made by Broadcom to access Wi-Fi 802.11 a / b / g and Bluetooth. Broadcom also supplies chips for the GPS receiver. GSM/3G signal receiver used for artificial chips Skyworks.

iPhone 4 Nexus One artificial trail Google has a dual microphone for improved audio quality, and reduce the noise disturbance. Both sensors placed far apart the possibility one of them to receive signals from the User and other sound capture noise from the surrounding noise.

Components that can not be missed is the iPhone that uses LED LCD backlight. LCD is coated with a special glass of alkali aluminosilicate material is 20 times harder and 30 times stronger than plastic. This layer is strongly affixed to the LCD and touch screen digitizer for the system so that if one part should be replaced rusah everything.
