1 / 78 page  TNETX15AE ADDRESS-LOOKUP DEVICE SPWS041A – AUGUST 1997 – REVISED OCTOBER 1997 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Provides up to 8K-Address Matching System D Provides Glueless External-Address Match (EAM) Interface to the TNETX3150/TNETX3150A/TNETX3100 D Uses Standard Off-the-Shelf 15-ns SRAMs D EEPROM Interface for Auto-Configuration, No CPU Needed D Automatic Aging Through User-Selectable Aging (AGE) Threshold D Fabricated in 3.3-V Low-Voltage Technology D Requires 3.3-V and 5-V Power Supplies D 5-V Tolerant I/Os D Provides Direct Input/Output (DIO) Interface for Management Access and Control (MAC) of the Address-Lookup Table D Address Lookups, Adds, and Deletes Are Automatically Performed in Hardware D User-Selectable Interrupts Simplify the Management Operations D Secure Addresses From Changing Ports D MII Data I/O (MDIO) PHY Management Interface D Management Access to Statistic Registers D JTAG Compliant D Packaged in 144-Terminal Plastic Quad Flatpack description The TNETX15AE performs the address-lookup function for either the TNETX3150/TNETX3150A or the TNETX3100 Ethernet ™ switch. The TNETX15AE device determines the addresses to use and match from the TNETX3150/TNETX3150A/TNETX3100 DRAM bus. The address-lookup table is maintained in external SRAM. The frame-matching and routing information is given to the TNETX3150/TNETX3150A/TNETX3100 through the external address-matching (EAM) interface. The TNETX15AE is designed to work in either unmanaged or managed mode. Unmanaged operation is accomplished through EEPROM support. Startup options are auto-loaded into the TNETX15AE registers using the EEPROM interface. If the TNETX15AE is initialized by automatic loading from the EEPROM, it begins operation automatically. All functions of this device are fully controllable by management through a direct input/output (DIO) interface. In addition, this device can interrupt the external management processor with user-selectable interrupts. This device also provides support for easy management control of IEEE Std 802.3u media-independent interface (MII) managed devices. A typical application is shown in Figure 1.
