Functional Overview
2
The Intel PXA270 processor is an integrated system-on-a-chip microprocessor for high
performance, dynamic, low-power portable handheld and hand-set devices as well as embedded
platforms. It incorporates the Intel XScale technology which complies with the ARM* version
5TE instruction set (excluding floating-point instructions) and follows the ARM* programmer’s
model. The PXA270 processor also provides Intel Wireless MMX media enhancement
technology, which supports integer instructions to accelerate audio and video processing. In
addition, it incorporates Wireless Intel Speedstep Technology, which provides sophisticated
power management capabilities enabling excellent MIPs/mW performance.
The PXA270 processor provides a scalable, bi-directional data interface to a cellular baseband
processor, supporting seven logical channels and other features. The operating-system (OS) timer
channels and synchronous serial ports (SSPs) also accept an external network clock input so that
they can be synchronized to the cellular network. The processor also provides a Universal
Subscriber Identity Module* (USIM) card interface.
The PXA270 processor memory interface gives designers flexibility as it supports a variety of
external memory types. The processor also provides four 64 kilobyte banks of on-chip SRAM,
which can be used for program code or multimedia data. Each bank can be configured
independently to retain its contents when the processor enters a low-power mode. An integrated
LCD panel controller supports displays up to 800 by 600 pixels, permitting 1-, 2-, 4-, and 8-bit gray
scale and 1-, 2-, 4-, 8-, 16-, 18-, and 24-bit color pixels. A 256-byte palette RAM provides flexible
color mapping.
A set of serial devices and general-system resources offers computational and connectivity
capability for a variety of applications.

processor system.
