Folks from iFixIt.com have disassembled Kindle 2 and here is brief scoop of what they’ve found:
- Battery used is 3.7V 1530mAh Li-Pol battery model number S11S01A. It weights 1.1 oz which is 10% of total weight of the device. It has slightly less capacity than iPhone 3G battery which is 1400mAh. Freescale MC13783VK5 is used as a battery power management chip.
- There is no protective cover on the display. So if you scratch it or break it repairs would be quite expensive.
- Main processor used is MCIMX31LVKN5C M91E CTAH0850V. It is ARM-11 CPU that runs at 533 Mhz and is manufactured by 90nm process. This is an upgrade from Kindle 1 which used 400 Mhz Marvell PXA255 CPU marked with LUPXA255A0 G7171929.2 0744 KR C400.
- RAM is represented by 128MB DDR Samsung K4X1G323PC chip. This is an upgrade compared to 64MB RAM found in Kindle 1.
- Flash memory is 2GB moviNAND. Major upgrade from 256MB built in Kindle 1, but as we know it comes at a cost of not having external SD slot.
- There is unused space on the PCB for SIM card. This hints to possibility of international versions of Kindle.
We’ll probably get much more comprehensive coverage on Kindle 2 once Igor from Reversing Everything gets his hands on one.
