Description
Designed specifically to address high-end embedded
applications for storage, the PowerPC 440SP
Embedded Processor (PPC440SP) 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, a DDR2 SDRAM controller,
configurable 256KB SRAM to be used as L2 cache or
software-controlled on-chip memory, three DDR PCI-X
bus interfaces, an Ethernet interface, an I2O/DMA
controller, control for external ROM and peripherals,
optional RAID 6 acceleration, an XOR DMA unit, serial
ports, IIC interfaces, and general purpose I/O.
