Features

• Proven Integrated 3-Port 10/100 Ethernet Switch

– 2nd generation switch with three MACs and two

PHYs fully compliant to IEEE 802.3u standard

– Non-blocking switch fabric assures fast packet

delivery by utilizing a 1K MAC address lookup table

and a store-and-forward architecture

– Full duplex IEEE 802.3x flow control (pause) with

force mode option

– Half-duplex back pressure flow control

– Automatic MDI/MDI-X crossover with disable and

enable option

– 100BASE-FX support on port 1

– MII interface supports both MAC mode and PHY

mode

– 7-wire serial network interface (SNI) support for

legacy MAC

– Comprehensive LED Indicator support for link,

activity, full/half duplex and 10/100 speed

• Comprehensive Configuration Register Access

– Serial management interface (SMI) to all internal

registers

– MII management (MIIM) interface to PHY registers

– SPI and I

2C Interface to all internal registers

– I/0 Pins strapping and EEPROM to program

selective registers in unmanaged switch mode

– Control registers configurable on the fly (port-

priority, 802.1p/d/q, AN…)

• QoS/CoS Packet Prioritization Support

– Per port, 802.1p and DiffServ-based

– Re-mapping of 802.1p priority field per port basis

• Advanced Switch Features

– IEEE 802.1q VLAN support for up to 16 groups

(full-range of VLAN ID)

– VLAN ID tag/untag options, per port basis

– IEEE 802.1p/q tag insertion or removal on a per

port basis (egress)

– Programmable rate limiting from 0Mbps to

100Mbps at the ingress and egress port, rate options

for high and low priority per port basis

– Broadcast storm protection with % control (global

and per port basis)

– IEEE 802.1d spanning tree protocol support

– Upstream special tagging mode to inform the

processor which ingress port receives the packet

– IGMP v1/v2 snooping support for multicast packet

filtering

– Double-tagging support

• Switch Management Features

– Port mirroring/monitoring/sniffing: ingress and/or

egress traffic to any port or MII

– MIB counters for fully compliant statistics

gathering, 34 MIB counters per port

– Loopback modes for remote diagnostic of failure

• Low Power Dissipation: <0.8 Watts (includes PHY

transmit drivers)

– Full-chip hardware power-down (register

configuration not saved)

– Per port based software power-save on PHY (idle

link detection, register configuration preserved)

– 0.18um CMOS technology

– Voltages: Core 1.8V

I/O and Transceiver 3.3V

Use K8993ML for 3.3V only operation

• Industrial Temperature Range: –40

oC to +85oC

• Available in128-Pin PQFP

Applications

• Universal Solutions

– Broadband gateway / Firewall / VPN

– Integrated DSL or cable modem multi-port router

– Wireless LAN access point + gateway

– Residential and enterprise VoIP gateway/phone

– Set-top/game box

– Home networking expansion

– Standalone 10/100 switch

– FTTx customer premises equipment

– Fiber broadband gateway

• Upgradeable Solutions

(1)

– Unmanaged switch with future option to migrate to

a managed solution

– Single PHY alternative with future expansion

option for two ports

• Industrial Solutions

– Applications requiring port redundancy and port

monitoring

– Sensor devices in redundant ring topology

Note:

1. The cost and time of PCB re-spin.
