The PPMC440GP reference design comes complete with detailed schematics, a VxWORKS.5.5 board support package, user documentation, and power supply. The PPMC440GP can either be operated as a standalone board or mounted on a PPMC carrier board and connected to other boards or peripherals through a PCI interface. Wind River's PPMC440GP comes standard with 256Mb of DDR SDRAM implemented through an unbuffered, 64-bit wide memory interface using a standard 200-pin DDR SDRAM SODIMM, 8MB of Primary FLASH, and 2MB of Backup FLASH. The PPMC440GP supports a PCI Rev 2.0 and PCI-X Rev 1.0-compliant interface when plugged into a PCI carrier board. Also standard are (2) 10/100Base-T RMII/SMII Ethernet Ports using the Ethernet MACs on the AMCC 440GP, an AC014Z SMII/RMII Transceiver and RJ45 connectors, a 16-pin JTAG interface connection, (2) 3-wire RS-232 Ports using the AMCC 440GP's on-chip UARTs, a real-time clock connected to the peripheral bus of the AMCC 440GP, 8KB of NvRAM, reset configuration of the AMCC 440GP via jumpers, and two serial I2C EPROMs.
