The A5 can be seen in the centre of the board. If we look at the package we can identify the Apple’s APL0498 marking for the A5 (the A4 is APL0398), and also 4 Gb of Elpida mobile DRAM. Date codes are 1107 for the A5 and 1103 for the memory – only a few weeks in the supply chain here!

The x-ray images show us that we have the usual package-on-package (PoP) structure, with two memory chips in the top part of the PoP, and the APL0498 processor on the lower half.
