Functional Overview
Electrical, Mechanical, and Thermal Specification
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.
