36 |Intel ® Network Processors and Intel ® I/O ProcessorsCore: Intel XScale ® TechnologyIntel XScale ® Technology is available in two families: The Intel ® network processors familyand the Intel ® I/O processors family of devices. With a single architecture and integrateddesign, the Intel ® IXP4XX product line of network processors delivers scalable performance,reduced power, and lower cost in packages optimized for residential and small/mediumenterprise network applications, as well as communications-based embedded applications.Many storage, networking, and embedded applications require fast I/O throughput foroptimal performance. Intel ® I/O processors (IOP) allow applications to transfer data faster,reduce communication bottlenecks, and improve overall system performance.Features • Intel XScale ® Microarchitecture running at up to 667 MHz• Intel ® network processors: Peripherals - USB, up to 3 10/100Ethernet MACs, PCI, DDR, Expansion Bus, UARTs, I 2 C, SSP• Intel ® network processors: Advanced Serial Interfaces includinga high speed serial port for connecting to T1/E1 orSLICs/CODECs; UTOPIA-2 Support;• Intel ® network processors: Integrated support for cryptography,time synchronization and ECC memory• Intel ® I/O processors: Integrated Designs• Intel ® I/O processors: I/O Processing Performance• Comprehensive Set of Development ToolsIntel ® IXP46X Product Line Block DiagramPMU(AHB)UART921KBaudIEEE1588InterruptControllerUTOPIA-2/MII/SMIIMII/Quad SMIIMII/SMIITimers66.66 MHz Advanced Peripheral BusUART921KBaudGPIOController16 GPIOHSS-0NPEAMII/SMIIUTOPIA, AAL,HSS, HDLCNPE B1 MII orQuad SMIINPE CMII/SMIIAES, DESSHA-1/-256/-384/-512, MO5BridgeHSS-1Bridge133.32 MHz Advanced High-Performance BusQueue Flag BusCryptography UnitEAI, SHAHW RNGQueue Manager8KB SRAM133.32 MHz Advanced High-Performance BusDDR1-266ControllerBus Interface UnitI 2 USBUSB PCI Expansion BusC SSPDevice v1.1Host 2.0** Controller ControllerIntel XScale ® Core266/400/533/667 MHz32 KB Data Cache32 KB Instruction Cache2 KB Mini-Data Cache32-bit32-bit +Parity32-bit +ECCMemory Port InterfaceBenefits • Intel’s groundbreaking new microarchitecture provides very highprocessor performance with extremely low power consumption;Intel XScale ® technology provides the platform for the mostadvanced designs in storage, infrastructure and embeddedcommunications• Provides reduced overall system cost as well as ease ofconnectivity to industry standard peripherals/devices• Support for voice applications and connection to industry standardWAN interface• Improves performance and reliability• I/O processors are available in single- or dual-chip configurationsthis provides developers with pre-validated component sets,simplified board designs, and board-space cost savings• Offloads I/O processing functions, such as I/O interrupt processingand parity calculations from a host processor; I/O processors arealso excellent general-purpose processors for high-bandwidthapplications that require integrated processors with low powerconsumption and high-speed peripherals• Faster time-to-market and support for multiple tool-chains andoperating systems on the Intel XScale ® microarchitecture**USB 2.0 Host supports low-speed (1.5 Mb/s) and full-speed (12 Mb/s) modes.Arrow Electronics ARM Solutions1-866-910-3650
