Overview: .. KS8695 Product Brief
Revision 1.07 CENTAUR Integrated Multi-Port Gateway Solutions
The KS8695 “Multi-Port Gateway-on-a-Chip” delivers a new level of networking integration and performance for speeding broadband gateway development. The key ponents integrated in the KS8695 include: • Integrated layer-2 managed switch with five Fast Ethernet transceivers and patented mixed-signal low-power technology; five MAC units; a high-speed non-blocking switch fabric; a dedicated address lookup engine; an on-chip frame buffer memory and LED controls. One port is partitioned for WAN interface with the other 4 ports for LAN access. • A 185-MIPS ARM 922T processor with memory management unit (MMU) and 8kB I-cache and 8kB D-cache. • An independent MAC unit supporting MAC or PHY mode MII interface for networking expansion. • On checksum errors and TCP/UDP/IP packet header checksum generation. The protocol engine applies to the WAN, LAN and EMAC interfaces. • DMA engines with burst mode support; Tx and Rx FIFOs to streamline the data transfers between WAN and CPU, CPU and LAN, CPU and EMAC. • 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. plete hardware & software reference designs are available. The KS8695 represents a new level of total solution optimized for broadband gateway system development and renders speedy routing performance & connectivity interfaces for value-added networking expansions.
