It’s the teardowns that make things interesting.

Per iFixit, the teardown of the seventh-gen iPod nano revealed the following interesting components:

– The Toshiba THGBX2G7D2JLA01, which includes 16 gigabytes of NAND flash. The Broadcom BCM2078KUBG also includes both the Bluetooth and FM radios.

– A touchscreen controller from Texas Instruments identified as 343S0538.

– A chip from NXP Semiconductors labeled “1609A1″.

The device also contained the following mystery chips which have yet to be identified:
– 75203 23017

– 75292 98820

– 339S0193

– Apple 338S1099

– Apple 338S1146

iFixit also found that the battery in the new iPod nano is soldered directly to the logic board and adhered to the back of the display. They did find a plastic pull tab presumed to be in place for removing the battery, however they found the adhesive holding the battery in place was too strong.

The new 3.7V, 0.8Wh, 220 mAh battery is more than twice that of the 0.39 Wh rating of the sixth-generation iPod nano. The solutions provider also found that the LCD and digitizer glass are not fused together, which means each component could be replaced separately.

The same could not be said for the battery, Lightning connector, or volume controls, all of which are soldered to the logic board. Pulling out the logic board also removes the battery, button cable, Lightning connector, and headphone jack.

Stay tuned for additional details as they become available and if you’ve snagged a new seventh-generation iPod nano and have any feedback to offer about it, please let us know in the comments.
