KS8695X
Integrated Multi-Port High-Performance
Gateway Solution
Rev. 1.03
General Description
The CENTAUR KS8695X, Multi-Port Gateway-on-a-Chip,
delivers a new level of networking integration and
performance 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
dedicated 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 devices.
• Other peripheral support logic including GPIO, a
watchdog timer, an interrupt controller, and a JTAG
debugging interface.
Complete hardware and software reference designs are
available.
The KS8695X represents a new level of total solution
optimized for broadband gateway system development
and renders speedy routing performance and connectivity
interfaces for value-added networking expansions.
