The KS8695 “Multi-Port Gateway-on-a-Chip”

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 look-

up 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.

KS8695 Product Brief

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.
