General Description The KSZ8895MQ/RQ/FMQ is a highly-integrated, Layer 2 managed, five-port switch with numerous features designed to reduce system cost. Intended for cost-sensitive 10/100Mbps five-port switch systems with low power consumption, on-chip termination, and internal core power controllers, it supports high-performance memory bandwidth and shared memory-based switch fabric with non-blocking configuration. Its extensive feature set includes power management, programmable rate limit and priority ratio, tag/port-based VLAN, packets filtering, four-queue QoS prioritization, management interfaces, and MIB counters. The KSZ8895 family provides multiple CPU data interfaces to effectively address both current and emerging fast Ethernet applications when port 5 is configured to separate MAC5 with SW5-MII/RMII and PHY5 with P5-MII/RMII interfaces. The KSZ8895 family offers three configurations, providing the flexibility to meet different requirements: • KSZ8895MQ: Five 10/100Base-T/TX transceivers, one SW5-MII and one P5-MII interface • KSZ8895RQ: Five 10/100Base-T/TX transceivers, one SW5-RMII and one P5-RMII interface • KSZ8895FMQ: Three 10/100Base-T/TX transceivers on Ports 1, 2, 5 and two 100Base-FX transceivers on Ports 3, 4, one SW5-MII and one P5-MII interface All registers of MACs and PHYs units can be managed by the SPI or the SMI interface. MIIM registers can be accessed through the MDC/MDIO interface. EEPROM can set all control registers for the unmanaged mode. Applications • Typical • VoIP phone • Set-top/game box • Automotive • Industrial control • IPTV POF • SOHO residential gateway • Broadband gateway/firewall/VPN • Integrated DSL/cable modem • Wireless LAN access point + gateway • Standalone 10/100 switch
