Description

Designed specifically to address embedded

applications, the NPe405L provides a high-

performance, low-power solution that interfaces to a

wide range of peripherals by incorporating on-chip

power management features and intrinsically lower

power dissipation requirements.

This chip contains a high-performance RISC

processor core, SDRAM controller, Ethernet

interfaces, HDLC interface, control for external

ROM and peripherals, DMA with scatter-gather

support, serial ports, IIC interface, and general

purpose I/O.
