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:
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.
A 166MHz ARM (ARM992T) processor with memory
management unit (MMU) and 8KB I-cache and 8KB D-
cache.

XceleRouter technology for the WAN and LAN
interfaces.
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.
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.
