Texas Instruments Inc. (TI) dominates the Kindle Fire design. Most notably, TI contributes the applications processor, which provides the core functionality of the tablet. The TI OMAP4430 processor costs $14.65, accounting for 7.9 percent of the Kindle Fire’s total BOM. However, TI also supplies other devices, including the power management device and the audio codec. This gives TI a total of $24 per each Kindle, or 12.9 percent of the BOM.
TI’s OMAP4430 applications processor has been identified in an increasing number of designs dissected by the IHS, including Research In Motion’s PlayBook RDJ21WW tablet, as well as the Motorola Droid Bionic XT875 and LG Optimus 3D P920 smartphones. The OMAP4430 is a dual-core ARM Cortex-A9, 1GHz processor with a IVA 3 Hardware Accelerator and a SGX540 3D graphics core. The device supports 1080P 2-D and 720P 3-D graphics, and is produced using 45nm process geometry.
The single most expensive subsystem in the Kindle Fire is the display and touch screen, at a combined cost of $87.00, or 46.9 percent of the BOM. Amazon sources the display from two companies: LG Display and E Ink Holdings. The display uses E Ink’s FFS technology, which LG Display has licensed.
