KSZ8864RMN  
Integrated 4-Port 10/100 Managed Switch  
with Two MACs MII or RMII Interfaces  
Rev. 1.4  
General Description  
The KSZ8864RMN is a highly-integrated, Layer 2  
managed 4-port switch with optimized design, plentiful  
features and smallest package size. 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 (see Functional Diagram) 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.
