PowerPC 440GR
Embedded Processor
With speeds 667MHz,support memory, ethernet NAND flash interfaces, power dissipation small footprint, PowerPC 440GR embedded processor ideally suited wide range highperformance applications, including networking storage. 440GR excellent choice 405xx users requiring additional performance looking upgrade memory.
Benefits
Delivers 333MHz 667MHz performance high-speed embedded designs Nand Flash Support Extensive connectivity onchip Ethernet, UARTs, IIC, Offers power dissipation small form factor highdensity power-conscious applications
PowerPC Core
enhance overall throughput, PowerPC superscalar core incorporates 7-stage pipeline executes instructions cycle. large 32KB data cache 32KB instruction cache 64way set-associative. Versatile configurations enhance performance tuning while optional parity protection preserves data integrity. additional system performance, PowerPC core includes dynamic branch prediction digital signal processing (DSP) instructions, well nonblocking caches that managed either writethrough write-back mode.
Interface
PowerPC 440GR offers 32-bit V2.2 interface supports frequencies 66MHz.Multiple read prefetch write post buffers enhance throughput, while ability boot processor from memory increases functionality.
Dual Ethernet Ports
extensive connectivity options, 440GR offers integrated 10/100 Ethernet ports.
Standard Peripherals
PowerPC 440GR offers serial ports, support General Purpose (GPIO) controllers. serial peripheral interface (SPI), also referred serial communications port (SCP), allows full-duplex, synchronous data exchanges with other serial devices. 440GR also supports four UARTs variety configurations. JTAG interface provided debugging purposes.
High Speed Architecture
Offering peak bandwidth 4.2GBps separate read write data buses PowerPC 440GR's Processor Local (PLB) provides high-bandwidth connection between processor core memory controller. Less demanding devices served 30-bit On-chip Peripheral (OPB).
Development tools support
PowerPC embedded processors supported AMCC more than hundred third-party vendors through PowerPC Embedded Tools program. This program provides compilers, debuggers, real-time operating systems, emulators, logic analyzers, full range tools help manufacturers develop products more quickly. PowerPC 440GR reference board available help expedite product evaluation project development.
Extensive Memory Support
on-chip Double Data Rate (DDR) SDRAM controller provides 32-bit memory interface with optional Error Checking Correcting (ECC) GBps peak data rate. supports memory banks 256MB each, maximum capacity 1GB. integrated Nand Flash controller allows four banks Flash memory devices connected processor's external peripheral bus. Flash controller supports device densities 512MB,an optional SmartMedia card interface. These devices accessed much like diskette drives, with available boot capability.
