KS8695P

Integrated Multi-Port PCI Gateway Solution

Micrel 

Micrel, Inc.

Features

The CENTAUR KS8695P featuring XceleRouter

technology is a single-chip, multi-port PCI "gateway-on-

a-chip" with all the key components integrated for a high-

performance and low-cost broadband gateway.

• ARM9 High-Performance CPU Core

– ARM9 core at 166MHz

– 8KB I-cache and 8KB D-cache

– Memory management unit (MMU) for Linux and WinCE

– 32-bit ARM and 16-bit thumb instruction sets for

smaller memory footprints

• 33MHz 32-Bit PCI Interface

– Version PCI 2.1

– Supports bus mastership or guest-mode

– Supports normal and memory-mapped I/O

– Support for miniPCI and cardbus peripherals

• Integrated Ethernet Transceivers and Switch Engine

– Five 10/100 Ethernet transceivers and five MACs (1P

for WAN interface, 4P for LAN switching)

– 100BASE-FX mode option on the WAN port and one

LAN port

– Automatic MDI/MDI-X crossover on all ports

– Wire-speed, non-blocking switch

– 802.1Q tag-based VLAN (16 VLANs, full range VID)

– Port-based VLAN

– QoS/CoS packet prioritization support: per port, 802.1p,

and DiffServ-based

– 64KB on-chip frame buffer SRAM

– VLAN ID and 802.1P tag/untag option per port

– 802.1D Spanning Tree Protocol support

– Programmable rate-limiting per port: 0Mbps to

100Mbps, ingress and egress, rate options for high and

low priority

– Extensive MIB counter management support

– IGMP snooping for multicast packet filtering

– Dedicated 1K entry look-up engine

– Port mirroring/monitoring/sniffing

– Broadcast and multicast storm protection with % control

global and per port basis

– Full- and half-duplex flow control

• XceleRouter Technology

– TCP/UDP/IP packet header checksum generation to

offload CPU tasks

– IPv4 packet fi ltering on checksum errors

– Automatic error packet discard

– DMA engine with burst-mode support for efficient

WAN/LAN data transfers

– FIFOs for back-to-back packet transfers

KS8695P

– Intel®/AMD®-type Flash support

• Peripheral Support

– 8/16/32-bit external I/O interface supporting PCMCIA or

generic CPU/DSP host I/F

– Sixteen general purpose input/output (GPIO)

– Two 32-bit timer counters (one watchdog)

– Interrupt controller

• System Design

– Up to 166MHz CPU and 125MHz bus speed

– 289 PBGA package (19mm x 19mm) saving board real

estate

– Two power supplies: 1.8V core and Ethernet RX

supply, 3.3V I/O and Ethernet TX supply

• Power Management

– CPU and system clock speed step-down options

– Low-power Ethernet transceivers

– Per port power-down and Ethernet transmit disable

• Reference Hardware and Software Evaluation Kit

– Hardware evaluation board (passes class B EMI)

– Board support package including firmware source

codes, Linux kernel, and software stacks

– Complete hardware and software reference designs

available
