DESCRIPTION
Designed specifically to address embedded applica-
tions, the NPe405H provides a high-performance, low-
power solution that interfaces to a wide range of
peripherals by incorporating on-chip power manage-
ment features and lower power dissipation
requirements.
This chip contains a high-performance RISC proces-
sor core, SDRAM controller, PCI bus bridge, Ethernet
EMACs, HDLC controllers, external bus controller for
ROM, Flash, and peripherals, DMA with scatter-gather
support, serial ports, IIC interface, and general pur-
pose I/O.
