Hot-selling and scarce KS8695X Integrated Multi-Port High-Performance Gateway Solutions QFP208 spot stock

Product Descriptions

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 lowpower 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 Dcache.

•  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.
