PXA27x Processor Family Design Guide 1.2 Functional Overview The PXA27x processor offers an integrated system-on-a-chip design based on the Intel XScale ® Microarchitecture. The PXA27x processor integrates the Intel XScale ®1 Microarchitecture core with many on-chip peripherals that allows design of many different products for the handheld and cellular handset markets. Figure 1 is the block diagram for the PXA27x processor.
