New iPod touch internals
Posted By admin On September 12, 2008 @ 2:43 am In All,Hardware | 1 Comment
The folks at iFixIt received a brand new iPod Touch , which they disassembled right away.
Both the touch's 3.5-inch LCD display as well as its Lithium-ion polymer battery are held in place with strips of double-sided tape. The WiFi antenna and circuitry, which are located at the top of the unit, are connected to the main logic board by wide orange cable that were designed to prevent external noise from interfering with the digital signals as they travel along the device, iFixIt says.
The specialty online reseller, which offers replacement parts for Macs and iPods, was particularly excited by its discovery of an unpublicized Broadcom BCM4325 Bluetooth  chip within the device. The particular chipset supports BT2.1+EDR, and is necessary for the touch's built-in support of Nike+ iPod technology. It's unclear, however, whether the chip supports A2DP, which would pave the way for Apple and third-party developers  to introduce stereo headphones for the player.
iFixIt also discovered brown rectangular component centered about three quarters of the way down the touch's logic board, which is suspected to be the device's speaker. Other  discoveries include a 3.7 V Lithium-ion polymer battery with part number 616-0404, NAND flash memory from Micron with part number 29F64G08TAA, and an Apple-branded Samsung -manufactured ARM processor with SDRAM that's similar to the one employed by the iPhone.
