    Of all the new iPods released by Apple, the Nano was the one which experienced the most redesign. Gone is the click wheel – replaced with a new touchscreen. Taking a look inside this small unit revealed numerous Apple-branded packages which required decapping to determine what they were. The brains of the device is a package-on-package chip featuring Samsung memory and a Samsung ARM application processor. The Apple 339S0104, when decapped, revealed a Samsung APL3278A01 ARM application processor and 512 Mb of Mobile DDR SDRAM from Samsung (part number K4X51323PI).

    The Apple device marked 337S3907 is actually the Cypress CY8C20746B, which is the controller for the new touchscreen of the iPod Nano.

    Dialog Semiconductor gets another design win, albeit not with their D1815A power management unit but their D1830B power management unit. This part was marked with 338S0783.

    Lastly, the FM receiver is located in a package marked 0650 D0UW. This is a Silicon Labs part – Si4800.
