Description
Designed specifically to address embedded
applications, the PowerPC 405GPr (PPC405GPr)
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 requirements.
This chip contains a high-performance RISC
processor core, SDRAM controller, PCI bus
interface, Ethernet interface, control for external
ROM and peripherals, DMA with scatter-gather
support, serial ports, IIC interface, and general
purpose I/O.
