Unmasked as the first low-power, security-enabled 400 series PowerPC processors, the 440GRx and 440EPx include an optional integrated security accelerator or turbo security engine to provide IPsec and SSL acceleration for supporting over 500 Mb/s of bandwidth. Both include a 64-bit DDR I or DDR II SDRAM controller with optional ECC, 32-bit PCI 2.2-compliant interface, dual Gigabit Ethernet MACs, four UARTs, one serial port, two IIC units, a NAND-flash controller, general purpose I/Os, and a programmable interrupt control. Groomed for networking, the 440GRx offers clock speeds up to 667 MHz and a superscalar architecture that can execute two instructions per clock cycle. It features a double-precision floating- point unit and USB 2.0 host/device functionality with an integrated PHY. For pricing, call AMCC, San Diego, CA. (800) 935-2622.
