Quick Detail:
Description:
The PXA255 processor provides high integration, high performance and low power consumption for portable handheld and handset devices. These processors incorporate the Intel® XScale™Microarchitecture based on the ARM* V5TE architecture. Refer to the Intel® XScale™
Microarchitecture for the Intel® PXA250 and PXA210 Applications Processors User’s Manual for implementation details, extensions, and options implemented by the XScale microarchitecture.
The processor memory interface supports a variety of memory types that allow flexible design requirements. Hooks for connection to two companion chips permit glueless connection to external devices. An integrated LCD display controller supports displays and permits 1, 2, and 4-bit grayscale, and 8- or 16-bit color pixels. A 256-byte palette RAM provides flexible color mapping capabilities.
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® PXA255 Processor Developer's Manual.
