Nano 5G

Components

Label	Component	Part	Markings	Notes
2	CPU	Samsung S5L8730	339S0081 ARM, K4X51323PG-UGC6, EDE168AG 0928, APL0378A00, N1X2XW 0931	Printed backwards on the chip - how sneaky. ARM1176JZF-S core (per CP15 data).
	SDRAM			Integrated into the processor, similar to the iPod Touch and iPhone lines.
8	NAND Flash	Various 8/16 GB chips	TH58NVG6D2ELA49, ID8038, TAIWAN, 09299AE	One example is TH58NVG6D2ELA49 visible on the iFixit Teardown
1	Power manager	Probably Dialog	338S0707, -AD, 09278HGZ	Similar looking and named chips like this have been power managers. Apple uses chips like these in just about every device.

5	Audio codec	Cirrus Logic CLI1480A	338S0559, ATWV0926, SGP	Also found in the Touch 3G. Stereo CODEC w/ Headphone and Speaker Amp
6	Accelerometer	LIS331DLM	33DM, 2910	The newer Touch's, iPhone's, and even the iPad have similar accelerometers, and I've discovered a pattern in the chip names.
