Key Benefits

• Single-chip Ethernet controller

- Fully compliant with IEEE 802.3/802.3u standards

- Integrated Ethernet MAC and PHY

- 10BASE-T and 100BASE-TX support

- 100BASE-FX support for external fiber transceiver

- Automatic polarity detection and correction

(HP Auto-MDIX)

- Full- and Half-duplex support

- Full-duplex flow control

- Backpressure for half-duplex flow control

- Preamble generation and removal

- Automatic 32-bit CRC generation and checking

- Automatic payload padding and pad removal

- Loop-back modes

• Eliminates dropped packets

- Internal buffer memory can store over 200 packets

- Automatic PAUSE and back-pressure flow control

• Flexible address filtering modes

- One 48-bit perfect address

- 64 hash-filtered multicast addresses

- Pass all multicast

- Promiscuous mode

- Inverse filtering

- Pass all incoming with status report

- Disable reception of broadcast packets

• 8/16-Bit Host Bus Interface

- Indexed register or multiplexed bus

- 16Kbyte FIFO with flexible TX/RX allocation

- SPI / Quad SPI support

• IEEE 1588v2 hardware time stamp unit

- Global 64-bit tunable clock

- Ordinary clock: master / slave, one-step / two-step, end-

to-end / peer-to-peer delay

- Fully programmable timestamp on TX or RX,

timestamp on GPIO

- 64-bit timer comparator event generation (GPIO or IRQ)

• Comprehensive power management features

- 3 power-down levels

- Wake on link status change (energy detect)

- Magic packet wakeup, Wake on LAN (WoL), wake on

broadcast, wake on perfect DA

- Wakeup indicator event signal

- Link status change

• Power and I/O

- Integrated power-on reset circuit

- Latch-up performance exceeds 150mA

per EIA/JESD78, Class II

- JEDEC Class 3A ESD performance

- Single 3.3V power supply

(integrated 1.2V regulator)

• Additional Features

- Multifunction GPIOs

- General purpose timer

- Optional EEPROM interface

- Ability to use low cost 25MHz crystal for reduced BOM

• Packaging

- Pb-free RoHS compliant 64-pin QFN or 64-pin TQFP-

EP

• Available in commercial, industrial, and extended

industrial* temp. ranges

*Extended temp. (105ºC) is supported only in the 64-QFN with an

external voltage regulator (internal regulator must be disabled) and

2.5V (typ) Ethernet magnetics.
