PPC440GP Datasheet PDF - Applied Micro Circuits Corporation

Description
   Designed specifically to address high-end embedded applications, the PowerPC 440GP (PPC440GP) provides a high-performance, low power solution that interfaces to a wide range of peripherals by incorporating on-chip power management features and lower power dissipation.
   This chip contains a high-performance RISC processor core, DDR SDRAM controller,8KB SRAM, PCI-X bus interface, Ethernet interfaces, control for external ROM and peripherals, DMA with scattergather support, serial ports, IIC interface, and general purpose I/O.
