| Intel PXA210/250 XScale-based Application Processors |
[Vendor: Intel]
Many of today's wireless and handheld devices sacrifice processing horsepower in order to maximize battery life. This trade-off does not impact the ability to manage simple personal information such as calendars and phone numbers. However, processors used in many current handheld products are unable to power popular compute-intensive consumer applications such as mobile digital music, Internet access, color video and gaming.
The new Intel PXA250 and Intel PXA210 applications processors allow makers of wireless communications devices to take the next step in high-performance and low-power wireless handheld computing technology. Products using the new processors are expected to be available to consumers by mid-2002.
The Intel PXA 250 applications processor runs at clock speeds up to 400 MHz and delivers the advanced integration, leadership multimedia performance, and improved power savings required for many full-featured handheld communicators, telematics systems and PDAs. Running at speeds up to 200 MHz, the Intel PXA210 applications processor delivers a highly integrated, low-power solution for cell phones and entry-level handheld and wireless devices.
Building on Intel StrongARM technology, the Intel XScale microarchitecture core was engineered to improve the performance of a wide variety of wireless Internet devices as well as powering networking infrastructure equipment. Both technologies are fully ARM architecture compliant, enabling software compatibility for products based on Intel StrongARM and Intel XScale microarchitectures.
These new processors feature architectural enhancements including support for the new Turbo mode technology. Turbo mode enables the processor to scale the performance as high or as low as necessary in a single clock cycle, which helps conserve battery life while still providing the necessary boosts in performance. In addition, the new micro-power management features for these devices allow the new processors to potentially use less than half the power at the same performance levels of today's Intel StrongARM SA-1110 applications processor.
To increase multimedia efficiency and performance, Intel also added Intel Media Processing Technology. It is designed to work specifically with the device's audio, video and gaming applications to increase the number of frames per second in videos, improve sound quality and give advanced graphical effects.
Product Highlights: - 32-bit Intel XScale core-based CPU (200/300/400 MHz for the PXA250; 133/200 MHz for the PXA210)
- ARM Architecture v.5TE compliant and application code compatible with Intel SA-1110 processor
- Intel Superpipelined RISC technology utilizing advanced Intel 0.18µ process for high core speeds at low power

- Low Power and Turbo modes for optimal battery life
- 32 KB data and 32 KB instruction caches
- 2 KB mini data cache for streaming data
- Integrated Memory and PCMCIA/CompactFlash Controller with 100MHz Memory Bus, 16-bit or 32-bit ROM/Flash/SRAM six banks, 16-bit or 32-bit SDRAM, SMROM four banks, as well as PCMCIA and CompactFlash for added functionality and expandability
- System Control Module includes dedicated general-purpose interruptible I/O ports, real-time clock, watchdog and interval timers, power management controller, interrupt controller, reset controller, and two on-chip oscillators
- Peripheral Control Module offers 16-channel configurable DMA controller, integrated LCD controller with unique DMA for fast colorscreen support, Bluetooth I/F, serial ports (IrDA, I2C, I2S, AC97,three UARTs, SPI and SSP), USB end point interface, and MMC/SDCard Support for expandable memory and I/O functionality
The PXA210/250 Application Processors are supported by several implementations of Embedded Linux.
