Yes it's an Intel XScale CPU.

...and from Wikipedia:

The PXA25x family consists of the PXA250 and PXA255. The PXA250 was Intel's first generation of XScale processors. There was a choice of three clock speeds: 200 MHz, 300 MHz and 400 MHz. It came out in February 2002. In March 2003, the revision C0 of the PXA250 was renamed to PXA255. The main differences were a doubled bus speed (100 MHz to 200 MHz) for faster data transfer, lower core voltage (only 1.3 V at 400 MHz) for lower power consumption and writeback functionality for the data cache, the lack of which had severely impaired performance on the PXA250. The PXA25x family has very bad GPIO performance (a pin cannot be toggled more than two million times a second, even at multi-hundred-MHz CPU clock).
