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.
Technology: CMOS Cu-11, 0.13mm, 7-layer metal
Package: 29mm, 783-ball, 1mm pitch, Flip Chip-
Plastic Ball Grid Array (FC-PBGA)
Power (estimated): Less than 6W @533MHz
Supply voltages required: 3.3V, 2.5V, 1.8V, 1.5V
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,
an XOR DMA unit, serial ports, IIC interfaces, and
general purpose I/O.
