NPe405L General Description
Designed specifically to address embedded applications, the NPe405L provides a highperformance, 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.
Technology: IBM CMOS 6SF 0.25µm(0.18µm Leff)
Package: 324-ball (23mm) enhanced plastic ball grid array (E-PBGA)
Power (estimated): Typical 1.1W, Maximum ?.?W
