KS8993M/ML/MI
Integrated 3-Port 10/100 Managed
Switch with PHYs
Rev 1.04
General Description
The KS8993M, a highly integrated Layer 2 managed
switch, is designed for low port count, cost-sensitive
10/100 Mbps switch systems. It offers an extensive
feature set that includes tag/port-based VLAN,
quality of service (QoS) priority, management,
management information base (MIB) counters,
MII/SNI, and CPU control/data interfaces to
effectively address both current and emerging Fast
Ethernet applications.
The KS8993M contains two 10/100 transceivers with
patented mixed-signal low-power technology, three
media access control (MAC) units, a high-speed
non-blocking switch fabric, a dedicated address
lookup engine, and an on-chip frame buffer memory.
Both PHY units support 10BASE-T and 100BASE-
TX. In addition, one of the PHY unit supports
100BASE-FX.
The KS8993ML is the single supply version with all
the identical rich features of the KS8993M.

Description
No connect
Hardware pin overwrite
0 = Disable. All strap-in pins configurations are overwritten by
the EEPROM configuration data
1 = Enable. All strap-in pins configurations are overwritten by
the EEPROM configuration data, except for register 0x2C bits
[7:5], (port 2: auto-negotiation enable, force speed, force
duplex).
Port 2 Auto MDI/MDI-X
PD (default) = enable
PU = disable
Port 2 MDI/MDI-X setting when auto MDI/MDI-X is disabled.
PD (default) = MDI-X (transmit on TXP2 / TXM2 pins)
PU = MDI, (transmit on RXP2 / RXM2 pins)
1 = enable auto negotiation on port 1
0 = disable auto negotiation on port 1
1 = force port 1 to 100BT if P1ANEN = 0
0 = force port 1 to 10BT if P1ANEN = 0
1 = port 1 default to full duplex mode if P1ANEN = 1 and auto
negotiation fails. Force port 1 in full-duplex mode if P1ANEN
= 0.
0 = port 1 default to half duplex mode if P1ANEN = 1 and auto
negotiation fails. Force port 1 in half duplex mode if P1ANEN
= 0.
1 = always enable (force) port 1 flow control feature
0 = port 1 flow control feature enable is determined by auto
negotiation result.
