description
The TNETX15AE performs the address-lookup function for either the TNETX3150/TNETX3150A or the
TNETX3100 Ethernet鈩?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.
