The PXA210 was Intel's entry-level XScale targeted at [[mobile phone]] applications. It was released with the PXA250 in February 2002 and comes clocked at 133&nbsp;MHz and 200&nbsp;MHz.

The PXA25x family (code-named '''Cotulla''') consists of the PXA250 and PXA255. The PXA250 was Intel's first generation of XScale processors. There was a choice of three [[clock speed]]s: 200&nbsp;[[MHz]], 300&nbsp;MHz and 400&nbsp;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 internal bus speed (100&nbsp;MHz to 200&nbsp;MHz) for faster data transfer, lower core voltage (only 1.3&nbsp;V at 400&nbsp;MHz) for lower power consumption and [[Cache misses|writeback]] functionality for the data cache, the lack of which had severely impaired performance on the PXA250.
