Intel XScale PXA255 and PXA270 Processors

The Intel XScale architecture was specifically developed by Intel Corporation to target mobile communication devices : cell phones, PDAs, communicators, smartphones, tablet PCs. Intel XScale microprocessors featured with a wide range of on-chip peripherals, extented instruction set support, low power design and small physical dimensions while expressing high performance.

Intel XScale processors have backward compatible instruction set with ARM processor architecture and support ARMv5TE instruction set. Manufactured by 0.18um technology the Intel XScale core clocked at 200, 300 and 400MHz. Internal system bus runs at a half of the processor core frequency. A wide range of development and debugging tools (Performance Monitoring, Debug, JTAG) is available for Intel XScale processors. Effective power management can change the core frequency depending on CPU load. Intel XScale PXA255 processor is ideal candidate for battery powered communication devices which need LCD screen support.

PXA255 features and highlights:

• Low power and high performance 32bit RISC processor core at 200, 300 and 400 MHz
• ARMv5TE instruction set compatibility
• 0.18um manufacturing process
• Optimized access to Intel StrataFlash memory
• Extended temperature range from -40°C to 85°C
• Built-in LCD controller
