The PXA26x family (code-named Dalhart) consists of the PXA260 and PXA261-PXA263. The PXA260 is a stand-alone processor clocked at the same frequency as the PXA25x, but features a TPBGA package which is about 53% smaller than the PXA25x's PBGA package. The PXA261-PXA263 are the same as the PXA260 but have Intel StrataFlash memory stacked on top of the processor in the same package; 16 MB of 16-bit memory in the PXA261, 32 MB of 16-bit memory in the PXA262 and 32 MB of 32-bit memory in the PXA263. The PXA26x family was released in March 2003.
