KS8695PX
Micrel
Functional Description
Introduction
Micrel's KS8695PX, a member of the CENTAUR line of integrated processors, is a high-performance router-on-a-chip solu-
tion for Ethernet and 802.11 a/g/b based embedded systems. Designed for use in communication's routers, it integrates a
PCI to AHB bridge solution for interfacing with 32-bit PCI, miniPCI, and cardbus devices. The KS8695PX combines a proven
third generation 5-port managed switch, an ARM9 RISC processor with MMU, and ? ve physical layer transceivers (PHYs)
including their corresponding MAC units with Micrel's XceleRouter technology.
The KS8695PX is built around the 16/32-bit ARM9 RISC processor, which is a scalable, high-performance, microprocessor
developed for highly integrated system-on-a-chip applications. It also offers a con? gurable 8KB I-cache and 8KB D-cache
that reduces memory access latency for high-performance applications. The simple, elegant, and fully static design of the
KS8695PX is especially suitable for cost-effective, power-sensitive applications.
The KS8695PX contains ? ve 10/100 PHYs: four are for the local area network (LAN) and one is for the wide area network
(WAN). Connected to the PHYs are ? ve corresponding MAC units with an integrated Layer 2 managed switch. The combining
of the switch and the analog PHYs make the KS8695PX an extremely prudent solution for SOHO router applications, saving
both board space and BOM costs. The Layer 2 switch contains a 16Kx32 SRAM on-chip memory for frame buffering. The
embedded frame buffer memory is designed with a 1.4Gbps on-chip memory bus. This allows the KS8695PX to perform full
non-blocking frame switching and/or routing on the ? y for many applications
For the media interface, the KS8695PX supports 10BASE-T and 100BASE-TX, as speci? ed by the IEEE 802.3 standard,
and 100 BASE-FX on the WAN port and on one LAN port
The KS8695PX supports two modes of operation in the PCI bus environment: host bridge mode and guest bridge mode. In the
host bridge mode, the ARM9 processor acts as the host of the entire system. It con? gures other PCI devices and coordinates
their transactions, including initiating transactions between the PCI devices and AHB bus subsystem. An on-chip PCI arbiter
is included to determine the PCI bus ownership among PCI master devices. In host bridge mode, all I/O registers, including
those for the embedded switch, are con? gured by the ARM9 processor through the on-chip AMBA bus interface.
In guest bridge mode, all of the I/O registers are programmed by either the external host CPU on the PCI bus or the local
ARM9 host processor through the AMBA bus. The KS8695PX functions as a slave on the PCI bus with the on-chip PCI arbiter
disabled. The KS8695PXX can be con? gured by either the ARM9 CPU or the PCI host CPU. In both cases, the KS8695PX
memory subsystem is accessible from either the PCI host or the ARM9 CPU. Communications between the external host
CPU and the ARM9 is accomplished through message passing or through shared memory.
