Description
Designed specifically to address embedded
applications, the NPe405H 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 bridge,
Ethernet EMACs, HDLC controllers, external bus
controller for ROM, Flash, and peripherals, DMA
with scatter-gather support, serial ports, IIC
interface, and general purpose I/O.
