Integrated Multi-Port High-Performance Gateway Solutions

Rev. 1.02

General Description

The CENTAUR KS8695X, Multi-Port Gateway-on-a-Chip,

delivers a new level of networking integration and perfor-

mance for accelerating broadband gateway development.

Key components integrated in the KS8695X include:

鈥?Integrated Layer 2 managed switch with five Fast

Ethernet transceivers and patented mixed-signal low-

power technology, five media access control (MAC)

units, a high-speed non-blocking switch fabric, a dedi-

cated address look-up engine, an on-chip frame buffer

memory, and LED controls. One port is partitioned for

WAN interface with the other four ports for LAN access.

鈥?A 166MHz ARM鈩?(ARM992T) processor with memory

management unit (MMU) and 8KB I-cache and 8KB D-

cache.

鈥?XceleRouter鈩?technology for the WAN and LAN

interfaces.

鈥?Shared programmable 8/16/32-bit data bus and 22-bit

address bus with up to 64MB total memory space for

SDRAM, ROM, Flash, SRAM, and all peripheral de-

vices.

鈥?Other peripheral support logic including GPIO, a watch-

dog timer, an interrupt controller, and a JTAG debug-

ging interface.

Complete hardware and software reference designs are

available.

The KS8695X represents a new level of total solution opti-

mized for broadband gateway system development and

renders speedy routing performance and connectivity inter-

faces for value-added networking expansions.
