KSZ8895MLU  
Integrated 5-Port 10/100 Managed Switch  
Revision 1.2  
General Description  
The KSZ8895MLU is a highly-integrated Layer 2-  
managed 5-port switch with an optimized design and  
plentiful features, qualified to meet AEC-Q100 standard  
for automotive applications. It is designed for cost-  
sensitive 10/100Mbps 5-port switch systems with on-chip  
termination, lowest power consumption and internal core  
power controller. These features will save more 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 power management, programmable  
rate limit and priority ratio, tag/port-based VLAN, packets  
The KSZ8895MLU consists of 10/100 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 KSZ8895MLU  
contains five MACs and four integrated PHYs. All PHYs  
support 10/100Base-T/TX.  
All registers of MACs and PHYs units can be managed  
by the SPI interface or the SMI interface. MIIM registers  
of the PHYs can be accessed through the MDC/MDIO  
interface. EEPROM can set all control registers for the  
unmanaged mode.

prioritization, management interface, and MIB counters.  
Port 5 is a MAC 5 MII interface with PHY mode as  
default at switch side. The SW5-MII interface can be  
connected to a processor with a MAC MII interface.
