General Description
The SMSC LAN8700/LAN8700i is a low-power, industrial temperature (LAN8700i), variable I/O voltage,
analog interface IC with HP Auto-MDIX support for high-performance embedded Ethernet applications.
The LAN8700/LAN8700i can be configured to operate on a single 3.3V supply utilizing an integrated
3.3V to 1.8V linear regulator. An option is available to disable the linear regulator to optimize system
designs that have a 1.8V power plane available.
0.1 Architectural Overview
The LAN8700/LAN8700i consists of an encoder/decoder, scrambler/descrambler, wave-shaping
transmitter, output driver, twisted-pair receiver with adaptive equalizer and baseline wander (BLW)
correction, and clock and data recovery functions. The LAN8700/LAN8700i can be configured to
support either the Media Independent Interface (MII) or the Reduced Media Independent Interface
(RMII).
The LAN8700/LAN8700i is compliant with IEEE 802.3-2005 standards (MII Pins tolerant to 3.6V) and
supports both IEEE 802.3-2005 compliant and vendor-specific register functions. It contains a full-
duplex 10-BASE-T/100BASE-TX transceiver and supports 10-Mbps (10BASE-T) operation on
Category 3 and Category 5 unshielded twisted-pair cable, and 100-Mbps (100BASE-TX) operation on
Category 5 unshielded twisted-pair cable.
Hubs and switches with multiple integrated MACs and external PHYs can have a large pin count due
to the high number of pins needed for each MII interface. An increasing pin count causes increasing
cost.
The RMII interface is intended for use on Switch based ASICs or other embedded solutions requiring
minimal pincount for ethernet connectivity. RMII requires only 6 pins for each MAC to PHY interface
plus one common reference clock. The MII requires 16 pins for each MAC to PHY interface.
The SMSC LAN8700/LAN8700i is capable of running in RMII mode. Please contact your SMSC sales
representative for the latest RMII specification.
The LAN8700/LAN8700i referenced throughout this document applies to both the commercial
temperature and industrial temperature components. The LAN8700i refers to only the industrial
temperature component.

selected for operation on pin nINT/TXER/TXD4 (default).
When RXD3/nINTSEL is pulled low to VSS through a resistor,
TXER/TXD4 is selected for operation on pin nINT/TXER/TXD4.
Notes:

received 5-bit symbol code-group. Unless configured in this
mode, the pin functions as RX_ER.
Note: This pin has an internal pull-down resistor, and must not
be high during reset. The RX_ER signal is optional in
RMII Mode.
RX_DV O Receive Data Valid: Indicates that recovered and decoded data
nibbles are being presented on RXD[3:0].

sequence to determine if the internal regulator should turn on.
When the regulator is disabled, external 1.8V must be supplied
to VDD_CORE, and the voltage at VDD33 must be at least
2.64V before voltage is applied to VDD_CORE.
