1 / 113 page  TNETX15VE VLAN-ENGINE ADDRESS-LOOKUP DEVICE SPWS028B – APRIL 1997 – REVISED SEPTEMBER 1997 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Provides up to 2K-Address Matching System D VLAN Support for Single or Multiple ThunderSWITCH ™ Devices D Provides Glueless External-Address Match Interface to the TNETX3150/TNETX3150A D Uses Standard Off-the-Shelf 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 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 Provides Spanning-Tree Support D Secure Addresses From Changing Ports D MII Data I/O (MDIO) PHY Management Interface D Management Access to Statistic Registers D Packaged in 144-Terminal Plastic Quad Flatpack D JTAG Compliant description The TNETX15VE performs the VLAN-engine address-lookup function for the TNETX3150/TNETX3150A Ethernet ™ switch using a glueless interface. The TNETX15VE device determines the addresses to use and match from the TNETX3150/TNETX3150A DRAM bus. The address-lookup table is maintained in external SRAM. The frame-matching and routing information is given to the TNETX3150/TNETX3150A through the external address-matching (EAM) interface. The TNETX15VE is designed to work in either unmanaged or managed mode. Unmanaged operation is accomplished through EEPROM support. Startup options are auto-loaded into the TNETX15VE registers using the EEPROM interface. If the TNETX15VE 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 the following: MII-Managed Devices (optional) Microprocessor (optional) SRAM EEPROM DWE DCAS DRAS DD35–DD0 VLAN-Engine Address- Lookup Device TNETX15VE ThunderSWITCH TNETX3150/TNETX3150A EAM DIO EINT MDIO DRAM Copyright © 1997, Texas Instruments Incorporated PRODUCTION DATA information is current as of publication date.
