The iPod Touch finally shows us what's up its sleeve:

Apple A5 dual-core processor, with 4 Gb (512 MB) of Mobile DDR2 RAM, denoted by the H9TKNNN4KDBRCR silkscreen label on the A5

Toshiba THGBX2G8D4JLA01 256 Gb (32 GB) NAND flash

Apple 3381064 dialog power management IC (similar to the Apple 338S1131)

Murata 339S0171 Wi-Fi module

Broadcom BCM5976 touchscreen controller

Apple 338S1116 is unknown at this time (although it bears a striking resemblance to the Apple 338S1117 found in the iPhone 5)

STMicroelectronics low-power, three-axis gyroscope (AGD3/2229/E5GEK)
