Single-chip, low-cost, two port 10/100Mbps Ethernet
bridge/switch
- Provides packet switching functions between two
10/100Mbps, auto-negotiated on-chip Fast
Ethernet ports
- Ideal for dual speed repeater and 2-port bridge
applications
Incorporates two 802.3 compliant 10/100Mbps Media
Access Controllers
- Direct Interface to MII (Media Independent
Interface)
- Half/Full Duplex Support (up to 200 Mbps/port)
- IEEE 802.3 100Base-TX, T4, and FX compatible
- Support for backpressure in half-duplex mode
Auto-negotiation supported through MII Interface
- Can be disabled on a per-port basis
High-Performance Switching Engine
- Performs forwarding and filtering at full wire speed
- 148,800 packets/sec on each Ethernet port
Direct support for packet buffering
- Glueless interface to 1or 2Mbyte of 50ns EDO
DRAM
- Up to 1K buffers, 1536-bytes each
- Dynamic or fixed buffer allocation for each port
Supports ‘Store and Forward’ switching approach
- Low last-bit in to first-bit out delay
- Provides packet buffering in overloaded networks
High visibility LED interface
- 3 pin serial LED interface for detailed status
information per port
Advanced address recognition
- Intelligent address recognition mechanism enables
forwarding rate at full wire speed
- Self-learning mechanism
- Supports up to 16K Unicast addresses and
unlimited Multicast/Broadcast addresses
Low-power 0.5u 3.3V process (5V tolerant)
