    IP1826D/IP1826CC 24-port 10/100M + 2-port Giga Smart Switch Controller

    General Description :
    The IP 1826D/IP1826C is a non-blocking, store-and-forward architecture switch controller, which supports 24-port SS-SMII, 2-port RGMII/ SERDES, and one-port MII for a 24+ 2G smart switch application. With two built-in SERDES transceiver, The IP 1826C provides a very cost-effective solution for a 24+2 Gigabit fiber without external Gigabit Ethernet transceivers.
    Note: In the following paragraphs, 24-port SS-SMII is referred to as port 0 ~ port 23, 2-port RGMII as port 24 and port 25 and MII port as port 26 (P0 ~ P 26 in abbreviation). The PHY address for P0 ~ P23 are “8~31” respectively. The PHY address “ 1” and “ 2” correspond to P24 and P25 respectively.
    The IP 1826C embeds a 2.75Mb SSRAM for the use of packet buffer and 4K MAC address table. It provides a 2-wire CPU interface, which allows the designer to access to the register in IP 1826C itself, the external PHY’s and the EEPROM. The LED informations is provided through a 2-wire LED interface by IP1826C . With the external logic devices, the IP 1826C can show the status of link, speed, duplex and activity.
    In addition to the fundamental function such as the flow control, the broadcast storm control and the programmable MAC address aging time, the IP 1826C also supports many advanced features which allow the designer to implement the smart switch features. The IGMP (Internet Group Management Protocol) snooping provides a method to build a multicast link without complicated CPU code. The designer can also use the 2 levels of priority queue to support the real-time streaming application. Supporting both port_based and tag_based VLAN, the IP 1826C can partition the network traffic by programming the VLAN table. The access control based on the MAC layer, the IP layer and TCP/UDP layer provides a method for the designer to implment the Class of Service and the network security.
    The web management software ported on IP210, an ICPLUS 8051 based web controller, is provided for the designer to easily design a web management smart swicth. With the web management function, designers can remotely configure and monitor IP 1826C smart switches through browsers, such as Microsoft Internet Explorer, and no extra program is needed.
