Functional Description
Introduction
Micrel's KS8695P, 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 KS8695P 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 KS8695P 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 congurable 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
KS8695P is especially suitable for cost-effective, power-sensitive applications.
The KS8695P 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 KS8695P 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
KS8695P to perform full non-blocking frame switching and/or routing on the y for many applications.
For the media interface, the KS8695P supports 10BASE-T and 100BASE-TX, as specied by the IEEE 802.3 standard,
and 100 BASE-FX on the WAN port and on one LAN port.
The KS8695P 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 congures 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 congured 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 KS8695P functions as a slave on the PCI bus with the on-chip PCI
arbiter disabled. The KS8695PX can be congured by either the ARM9 CPU or the PCI host CPU. In both cases, the
KS8695P 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.
