KSZ8695PX

Specialized ICS Overview

The KSZ8695PX is a multi-port PCI gateway solution integrating an ARM922T CPU core operating at 166 MHz with 8KB I-cache and 8KB D-cache. It features a 33MHz 32-bit PCI interface (PCI 2.1) supporting bus mastership or guest-mode. The device includes five 10/100 Ethernet transceivers and MACs, with one WAN port supporting 100BASE-FX options. It provides a non-blocking switch engine with 64KB on-chip frame buffer SRAM, supporting 802.1Q VLAN, QoS, and IGMP snooping. External memory support includes up to 64MB via an 8/16/32-bit data bus. Power supplies are 1.8V for the core and 3.3V for I/O.

Specialized ICS Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm the specific ordering suffix matches the required temperature range and package variant. Check for lead-free compliance status as per RoHS directives. Ensure ESD handling procedures are followed due to moisture sensitivity. Validate that the source document corresponds to the exact part number KSZ8695PX.

Specialized ICS Selection Notes

Select this component for designs requiring a single-chip gateway solution with integrated switching and processing. Ensure the system design accommodates the 289-pin PBGA package dimensions of 19mm x 19mm. Verify power supply requirements for both 1.8V core and 3.3V I/O rails. Consider the need for external memory if more than 64MB address space is required. Confirm compatibility with the target operating system, such as Linux or WinCE, given the ARM9 MMU support.
