The KSZ8864 device consists of two PHYs and four MACs. Two of MACs support either MII or RMII interfaces for dual processor/DSP data transfer. Higher speed SPI and MDC/MDIO interfaces can fully manage the 4-port switch by the processor. The device had been designed with cost sensitive systems in mind but still offers a multitude of features such as switch management; port and tag based VLAN;

Higher speed SPI and MDC/MDIO interfaces can fully manage the 4-port switch by the processor. The device had been designed with cost sensitive systems in mind but still offers a multitude of features such as switch management; port and tag based VLAN; 1/2/4-queue QoS priority; a dual MII/RMII option data interfaces and CPU control interfaces of SPI, MDC/MDIO with MIIM/SMI. MIIM is the standard IEEE 802.3 MII Management Interface. SMI is non-standard Serial Management Interface that can access all registers by the Management Data Input/output MDIO interface. The KSZ8864 is an excellent choice in current complex Ethernet applications with single processor or dual processors, industrial automatic, automotive, etc. fields and as a standalone 4-port switch. The KSZ8864 evaluation board is designed to allow the user to experience first-hand the rich feature set of these existing 4-port switches of KSZ8864CNX/RMNUB. The evaluation board is highly configurable and easy to use.
