PXA210

The PXA250 and PXA210 applications processors provide high integration, high performance and low power consumption for portable handheld and handset devices. These applications processors incorporate Intel's XScaleTM Microarchitecture based on the ARM* V5TE architecture. Refer to the Intel® XScaleTM Microarchitecture for the Intel® PXA250 and PXA210 Applications Processors Developer's Manual for implementation details, extensions, and options implemented by Intel's XScaleTM Microarchitecture.

The applications PXA210 processor's memory interface supports a variety of memory types that allow flexibility in design requirements. Hooks for connection to two companion chips permit glueless connection to external devices. An integrated LCD display controller provides support for displays, and permits 1, 2 and 4 bit grayscale and 8 or 16 bit color pixels. A 256-byte palette RAM provides flexibility in color mapping.

A rich set of serial devices as well as general system resources provide enough compute and connectivity capability for many applications. For details on the programming model and theory of operation of each of these units, refer to the Intel® PXA250 and PXA210 Applications Processors Developer's Manual. For the applications processor's block diagram refer to Figure 1,"Applications Processor Block Diagram" on page 8.
