KSZ8895MLU_11 Datasheet, PDF (1/110 Pages) Micrel Semiconductor – Integrated 5-Port 10/100 Managed Switch

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, programmble
rate limit and priority ratio, tag/port-based VLAN, packets
filtering, quality of service (QoS) four-queues
prioritization, management interface, and MIB counters.
Port 5 is a MAC 5 MII interface with PHY mode. The
SW5-MII interface can be connected to a processor with
a MAC MII interface.
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 intergrated 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.
Datasheets and support documentation can be found on
feature set such as power management, programmble
rate limit and priority ratio, tag/port-based VLAN, packets
filtering, quality of service (QoS) four-queues
prioritization, management interface, and MIB counters.
Port 5 is a MAC 5 MII interface with PHY mode. The
SW5-MII interface can be connected to a processor with
a MAC MII interface.
The KSZ8895MLU provides multiple CPU control/data
interfaces to effectively address both current and
emerging fast Ethernet applications. Micrel’s web site at:
