KS8695P
Integrated Multi-Port PCI Gateway Solution
Rev. 1.5
General Description
The CENTAUR KS8695P, Multi-Port PCI Gateway
Solution, delivers a new level of networking integration,
performance, and overall BOM cost savings, enabling
original equipment manufacturers (OEMs) to provide
customers with feature-rich, low-cost solutions for the
residential gateway and small office environment.
• Integration of a PCI arbiter supporting three external
masters.
– Allows incorporation of a variety of productivity
enhancing system interfaces, including the expanding
802.11 a/g/b wireless LAN.
• High-performance ARM™ CPU (ARM9) with 8KB
I-cache, 8KB D-cache, and a memory management unit
(MMU) for Linux and WinCE® support.
• XceleRouter™ technology to accelerate packet
processing.
• Proven wire-speed switching technology that includes
802.1Q tag-based VLAN and quality of service (QoS)
support.
• Five patented mixed-signal, low-powered Fast Ethernet
transceivers with corresponding media access control
(MAC) units.
• Advanced memory interface with programmable 8/16/32-
bit data and 22-bit address bus with up to 64MB of total
memory space for Flash, ROM, SRAM, SDRAM, and
external peripherals.
