AX88782 -- Non-PCI 8/16-bit 2-Port 10/100M Fast Ethernet Controller The AX88782 is a single- 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 supports checksum offload engine and burst-mode acce making it easy to provide a high performance 2-port Ethernet connectivity solution for any embedded MCU. The built-in switching fabric in the AX88782 supports non-blocking wire-speed forwarding and offers an advanced switch feature set that includes tag/port-based VLAN, spanning tree, rate control, port security, port mirroring, IGMP snooping, MIB counters and four priority queues for QoS functions including Port-Based, 802.1p VLAN, IPv4 TOS and IPv6 COS to prioritize voice, video, audio and data traffic delivery. The AX88782 have integrated a voltage regulator and provide support for programmable I/O voltage options of 3.3V/2.5V/1.8V to enable a highly optimized system design. As semiconductor designs migrate to advanced proce geometries like 90nm, 65nm, 45nm and beyond, many of today's higher performance ASICs, SoCs and FPGAs require lower I/O voltages. The AX88782 combine the benefits of high integration and small form factor making them ideal single- solutions for designing high performance, QoS-aware and cost effective 2-port Ethernet functions for embedded system applications such as VoIP phone/ATA adapters, IP cameras, -generation IP-STB/, industrial controller/network , port redundancy/port monitoring and Single Board Computers (SBC) Feature: 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 acce, 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 backpreure 10/100M PHY supports twisted pair croover detection and auto-correction (HP Auto-MDIX) Supports Wake-on-by 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 ingre and egre programmable rate limit control Integrates two-way Addre-Lookup engine and table for 1K MAC addrees Supports Routing Table/IGMP/VTable acce 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 Vand IPv4 TOS/IPv6 COS packets with four priority queues Supports RFC2475 DiffServ-based V Supports up to 3 Vgroups for port-based Vand 16 Ventries for 802.1Q tag-based Vfunction Supports Double tagging 802.1Q-in-802.1Q function for WAN acce Security Supports ingre port security mode, incoming packets with unknown source MAC addre 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 addre snooping Monitoring Supports RMON group 1,2,3,9 counter (RFC1213) Supports Ethernet-like MIB counter (RFC 1643) Supports Bridge MIB counter (RFC 1493) Egre/Ingre Port Mirroring Sniffer functions Source/Destination Port DA/SA VID Ethernet Packet Type IPv4/IPv6 Protocol IPv4/IPv6 TCP/UDP Port Number Supports Interfaces Single 3.3V power supply with options for 1.8V, 2.5V and 3.3V I/O voltage support Integrates an on- voltage regulator requiring only a single power supply of 3.3V Integrates an on- oscillator and PLL requiring only a 25MHz crystal to operate Integrates on- power-on reset circuit 80-pin E-PAD LQFP RoHS compliant package Operating temperature range: 0°C to +70°CAbout shipping
