Marvell PXA255 XScale application processor
The Kindle's main processor is a Marvell PXA255 application processor, with the following markings: LUPXA255A0 G7171929.2 0744 KR C400. According to Wikipedia, Intel released the PXA210 and PXA25x family (PXA250 and PXA255) of XScale processors in 2002 as a replacement for its StrongARM line of processors.
XScale microprocessors are fifth generation ARM processors based on ARMv5TE architecture. According to Intel's PXA255 datasheet on Alldatasheet.com, the PSA255 supports a flexible CPU clock speed from 100 to 400 MHz. I assume the "C400" marking on the Kindle's chip indicates this is a 400 MHz version.
In some Kindles, these chips have an Intel logo. Intel sold the PXA processor assets to Marvell in 2006.
