KSZ8995M集成電路（IC）的專用IC規(guī)格書PDF中文資料

General Description

The KS8995M is a highly integrated Layer-2 managed switch with optimized BOM (Bill of Materials) cost for low port count, cost-sensitive 10/100Mbps switch systems. It also provides an extensive feature set such as tag/port-based VLAN, QoS (Quality of Service) priority, management, MIB counters, dual MII interfaces and CPU control/data interfaces to effectively address both current and emerging Fast Ethernet applications.

Features

? Integrated switch with five MACs and five Fast Ethernet transceivers fully compliant to IEEE 802.3u standard

? Shared memory based switch fabric with fully nonblocking configuration

? 1.4Gbps high-performance memory bandwidth

? 10BaseT, 100BaseTX and 100BaseFX modes (FX in Ports 4 and 5)

? Dual MII configuration: MII-Switch (MAC or PHY mode MII) and MII-P5 (PHY mode MII)

? IEEE 802.1q tag-based VLAN (16 VLANs, full-range VID) for DMZ port, WAN/LAN separation or inter-VLAN switch links

? VLAN ID tag/untag options, per-port basis

? Programmable rate limiting 0Mbps to 100Mbps, ingress and egress port, rate options for high and low priority, per-port-basis

? Flow control or drop packet rate limiting (ingress port)

? Integrated MIB counters for fully compliant statistics gathering, 34 MIB counters per port

? Enable/Disable option for huge frame size up to 1916 bytes per frame

? IGMP v1/v2 snooping for multicast packet filtering

? Special tagging mode to send CPU info on ingress packet’s port value

? SPI slave (complete) and MDIO (MII PHY only) serial management interface for control of register configuration

? MAC-id based security lock option

? Control registers configurable on-the-fly (port-priority, 802.1p/d/q, AN...)

? CPU read access to MAC forwarding table entries

? 802.1d Spanning Tree Protocol

? Port mirroring/monitoring/sniffing: ingress and/or egress traffic to any port or MII

? Broadcast storm protection with percent control – global and per-port basis

? Optimization for fiber-to-copper media conversion

? Full-chip hardware power-down support (register configuration not saved)
