• Manufacturer Part Number: PXA320
• Description: Cost-Effective, Scalable Performance up to 806 MHz for Power-Efficient, High-End Multimedia Handsets, Embedded Solutions, and Enterprise-Class Devices
• Manufacturer: MARVELL [Marvell Technology Group Ltd.]

FOUNDATION FOR A VERSATILE PLATFORM
The PXA320 processor integrates technologies into compact, powerful devices for network operators, enterprises,
and consumers. A new low-latency, fully connected internal memory switch eliminates memory bottlenecks, while separate
interfaces for 32-bit DDR memory and Flash memory (NANDX8, NANDX16, and NOR) provide performance for premium
phone features and platform flexibility. More and faster peripheral interfaces, including high-speed serial interfaces, enable
Wi-Fi, WiBro, and WiMAX connectivity. A built-in touch-screen and LCD controller supports high-end PDA phones and other
touch-screen driven devices. Plus support for removable memory cards makes the PXA320 processor ideal for a range
of designs needing performance and flexibility to address the needs of multiple market segments.
ENHANCED VIDEO AND AUDIO PERFORMANCE
The PXA320 processor enables next-generation, high-end, multimedia phones and PDAs, enterprise-class handhelds,
and personal media players, with D1-quality, streaming video playback at 30 fps, digital camcorder features up to CIF, 30fps,
5 MP camera capture, video telephony, and DVB-H. With a large frame buffer, new memory architecture, and support for faster
DDR memory, the PXA320 processor boosts video performance up to 40 percent over previous-generation PXA270 processors.
The PXA320 processor spends less time in active mode while decoding H.264 video streams, and delivers higher video
performance while lowering power consumption. And multimedia processing can take advantage of the SIMD instruction set
which includes new instructions for speech and video algorithms.
