Non-PCI 8/16-bit 2-Port 10/100M Fast Ethernet Controller [NOT FOR NEW DESIGN!!]

Add Favorites


The AX88782 is a single-chip 2-port 10/100M Ethernet Switch controllers featuring a 3-port switching fabric with QoS priority management, three 10/100M MACs, two 10/100M PHYs, and 8/16-bit Non-PCI host interface.

The AX88782 combine the benefits of high integration and small form factor making them ideal single-chip solutions for designing high performance, QoS-aware and cost effective 2-port Ethernet functions for embedded system applications such as VoIP phone/ATA adapters, surveillance IP cameras, next-generation IP-STB/IPTV, industrial controller/network sensors, port redundancy/port monitoring and Single Board Computers (SBC)


● High Performance Non-PCI Interface
-- Configurable 8/16-bit SRAM-like host interface (US Patent Approval), easily interfaces with most common embedded MCUs
-- Supports PPPoE/IPv4 IP/TCP/UDP/ICMP/ IGMP checksum offload to relieve CPU loading
-- Supports burst-mode access, minimizing CPU overhead
● Fast Ethernet MAC/PHY
-- IEEE 802.3 10Base-T/100Base-TX compatible
-- Supports full-duplex operation with IEEE 802.3x flow control and half duplex with backpressure
-- 10/100M PHY supports twisted pair crossover detection and auto-correction (HP Auto-MDIX)
-- Supports Wake-on-LAN by Microsoft Wakeup Frame, Magic Packet and link status change detection
● Switching Fabric
-- Performs non-blocking wire-speed forwarding and filtering
-- Embeds 32KB SRAM for packet buffering
-- Supports broadcast storm filtering
-- Supports per queue and per port ingress and egress programmable rate limit control
-- Integrates two-way Address-Lookup engine and table for 1K MAC addresses
-- Supports Routing Table/IGMP/VLAN Table access through CPU read/write operation
-- Supports 802.1D Spanning Tree Protocol and 802.1w Rapid Spanning Tree Protocol
● QoS
-- Supports Quality-of-Service for port-based, 802.1p VLAN and IPv4 TOS/IPv6 COS packets with four priority queues
-- Supports RFC2475 DiffServ-based
-- Supports up to 3 VLAN groups for port-based VLAN and 16 VLAN entries for 802.1Q tag-based VLAN function
-- Supports Double tagging 802.1Q-in-802.1Q function for WAN access
● Security
-- Supports ingress port security mode, incoming packets with unknown source MAC address could be dropped
-- Supports eight Security MAC Registrations
-- Supports 802.1X port-based Authorization
● Multicast
-- Supports GMRP/GVRP/GARP packet snooping
-- Supports IPv4 IGMP and IPv6 ICMP/MLD (Multicast Listener Discovery) Snooping
-- Supports up to 1K Multicast Group (shared with L2 MAC table)
-- Supports eight IGMP Multicast IP address snooping
● Monitoring
-- Supports RMON group 1,2,3,9 counter (RFC1213)
-- Supports Ethernet-like MIB counter (RFC 1643)
-- Supports Bridge MIB counter (RFC 1493)
-- Egress/Ingress Port Mirroring
-- Sniffer functions
○ Source/Destination Port
○ Ethernet Packet Type
○ IPv4/IPv6 Protocol
○ IPv4/IPv6 TCP/UDP Port Number
● Supports EEPROM Interfaces
● Single 3.3V power supply with options for 1.8V, 2.5V and 3.3V I/O voltage support
● Integrates an on-chip voltage regulator requiring only a single power supply of 3.3V
● Integrates an on-chip oscillator and PLL requiring only a 25MHz crystal to operate
● Integrates on-chip power-on reset circuit
● 80-pin E-PAD LQFP RoHS compliant package
● Operating temperature range: 0°C to +70°C
