INTEL PXA270 416MHZ ARM PROCESSOR

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.
