Functional Overview
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 XScale
TM
Microarchitecture based on the ARM* V5TE architecture. Refer to
the Intel
XScale
TM
Microarchitecture for the Intel
PXA250 and PXA210 Applications
Processors Developer's Manual for implementation details, extensions, and options implemented
by Intel
’
s XScale
TM
Microarchitecture.
The applications 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
