KSZ8864

The KSZ8864RMN is a highly-integrated, Layer 2 managed 4-port switch with optimized design, plentiful features and smallest package size.  The KSZ8864 supports Automotive applications. 

It is designed for cost-sensitive 10/100Mbps 4-port switch systems with on-chip termination, lowest-power consumption, and small package to save system cost. It has 1.4Gbps high-performance memory bandwidth, shared memory-based switch fabric with full non-blocking configuration.

It also provides an extensive feature set such as the power management, programmable rate limiting and priority ratio, tag/port-based VLAN, packet filtering, quality of service (QoS), four queue prioritization, management interface, MIB counters. Port 3 and Port 4 support either MII or RMII interfaces with SW3-MII/RMII and SW4-MII/RMII for KSZ8864RMN data interface. The KSZ8864RMN provides multiple CPU control/data interfaces to effectively address both current and emerging fast Ethernet applications.

The KSZ8864RMN consists of 10/100 fast Ethernet PHYs with patented and enhanced mixed-signal technology, media access control (MAC) units, a high-speed non-blocking switch fabric, a dedicated address lookup engine, and an on-chip frame buffer memory.

The KSZ8864RMN contains four MACs and two PHYs. The two PHYs support the 10/100Base-T/TX. All registers of MACs and PHYs units can be managed by the control interface of SPI or the SMI. MIIM registers of the PHYs can be accessed through the MDC/MDIO interface. EEPROM can set all control registers by I2C controller interface for the unmanaged mode.
