UPDATE: It seems as though the difference between the two chips may be more important than I had previously thought. The PD/ZB is the package code, and comparing the MT29TZZZ8D5JKEZB
to the MT29TZZZ8D5JKETS
-107 W.95Q it would appear as though the BGA is completely different (168 pin vs 221, layout also being completely different). I may just have to donate this FireTV basic to the cause and lift it. If i'm lucky my BGA rework skills are still half as good as the Xbox 360 days.
Did a bit of digging, and it seems the markings on the eMMC do not simply reflect any internal models of the chip (as evident by a simple google search), but luckily Micron has their own decoder you can use
The chip beside the ARM CPU appears to be an eMMC/RAM combo unit. Searching their site I cannot locate anything for MT29TZZZ8D5JKEPD
specifically, but there are some that are very close, like the MT29TZZZ8D5JKEZB
. The difference between the chips is one has 8GM RAM the other (which I can't find) is the FireTV Basic which has 1GB ram.
Regardless, it looks like we're gonna have to pull the chip to determine where the required BGA pins can be accessed externally as there doesn't appear to be anything close to the eMMC. My guess is the underside of the board will be where most the pins will be accessed (hopefully).
