KS8995MA
Integrated 5-Port 10/100 Managed Switch
Rev 2.4
General Description
The KS8995MA is a highly integrated Layer 2 managed
switch with optimized bill of materials (BOM) cost for low port
count, cost-sensitive 10/100Mbps switch systems. It also
provides an extensive feature set such as tag/port-based
VLAN, quality of service (QoS) priority, management, MIB
counters, dual MII interfaces and CPU control/data interfaces
to effectively address both current and emerging Fast Ether-
net applications.
The KS8995MA contains five 10/100 transceivers with pat-
ented mixed-signal low-power technology, five media access
control (MAC) units, a high-speed non-blocking switch fabric,
a dedicated address lookup engine, and an on-chip frame
buffer memory.
All PHY units support 10BASE-T and 100BASE-TX.
In addition, two of the PHY units support 100BASE-FX
(ports 4 and 5).
Features
Integrated switch with five MACs and five Fast Ethernet
transceivers fully compliant to IEEE 802.3u standard
Shared memory based switch fabric with fully non-
blocking configuration
1.4Gbps high-performance memory bandwidth
10BASE-T, 100BASE-TX, and 100BASE-FX modes
(FX in ports 4 and 5)
Dual MII configuration: MII-Switch (MAC or PHY mode
MII) and MII-P5 (PHY mode MII)
IEEE 802.1q tag-based VLAN (16 VLANs, full-range
VID) for DMZ port, WAN/LAN separation or inter-VLAN
switch links
VLAN ID tag/untag options, per-port basis
Programmable rate limiting 0Mbps to 100Mbps, ingress
and egress port, rate options for high and low priority,
per-port basis in 32Kbps increments
Flow control or drop packet rate limiting (ingress port)
Integrated MIB counters for fully compliant statistics
gathering, 34 MIB counters per port
