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. An
industrial temperature-grade version of the KSZ8864RMNI
and a qualified AEC-Q100 Automotive version of the
KSZ8864RMNU are also available (see “Ordering
Information” section).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 I
2C
controller interface for the unmanaged mode.
