As a "new" product, Kindle Fire HD utilizes a lot of old parts.
This year's Kindle Fire HD utilizes much of the guts of last year's model, with a similar motherboard and layout. Unlike last year's model, the front glass and LCD display aren't fused, making it more easy to repair.
The teardown found 1 gigabyte of SDRAM from Micron, flash memory from Toshiba, a touch-screen controller by Synaptics, and components from Texas Instruments, Broadcom, and Maxim Integrated, dealing with different radios and stereo audio codecs.
LG again provided the display.
