Benefits
Combines the proven performance of the market leading PPC464 processor with a high-performance suite of peripheral and memory interfaces.
Contains a high-performance RISC processor core, DDR SDRAM controller, configurable 256 KB SRAM to be used as L2 cache or software controlled on-chip memory, PCI Express one-lane interface, Gigabit Ethernet interface, TCP/IP acceleration hardware, USB 2.0 On-The-Go interface, Serial ATA interfaces, control for external ROM and peripherals, DMA with scatter/gather support, XOR DMA, serial ports, IIC interface, and general purpose I/O.
Ideally suited for the next generation NAS applications that require exceptional performance, a small footprint, and low power.
