About This Document

This is the electrical, mechanical, and thermal specification data sheet for the Intel® PXA255

Processor. This data sheet contains a functional overview, mechanical data, package signal

locations, targeted electrical specifications (simulated), and bus functional waveforms. Detailed

functional descriptions other than parametric performance is published in the Intel® PXA255

Processor Developer's Manual. Refer to Table 1, “Related Documentation” for a list of documents

that support the PXA255 processor.

Functional Overview

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. For the

processor block diagram, refer to Figure 1, “Processor Block Diagram” on page 8.
