Features

Product Brief

High-performance non-PCI local bus

Supports 8/16-bit SRAM-like host interface

(US Patent Approval), easily interfaced to

most common embedded MCUs; or 8/16-bit

local CPU interface including MCS-51 series,

Renesas series CPUs

Supports

Slave-DMA to

minimize

CPU

overhead and burst mode read & write access

for

frame

reception

&

transmission

on

SRAM-like interface for high performance

applications

Supports variable voltage I/O (1.8/2.5/3.3V)

and programmable driving strength (8/16mA)

Interrupt pin with programmable timer

High-performance SPI slave interface

Supports SPI slave interface for CPU with

SPI master. The SPI slave interface supports

SPI timing mode 0 and 3, up to 40MHz of

SPICLK,

variable

voltage

I/O

and

programmable driving strength

Supports optional Ready signal as flow

control for SPI packet RX/TX

Single-chip

Fast

Ethernet

MAC/PHY

controller

Embeds 14KB SRAM for packet buffers

Supports IPv4/IPv6 packet Checksum Offload

Engine to reduce CPU loading, including

IPv4 IP/TCP/UDP/ICMP/IGMP and IPv6

TCP/UDP/ICMPv6 checksum generation &

check

Supports VLAN match filter

Integrates

IEEE

802.3/802.3u

standards

compatible

10BASE-T/100BASE-TX

(twisted pair copper mode) Fast Ethernet

MAC/PHY transceiver in one single-chip

Supports twisted pair crossover detection and

correction (HP Auto-MDIX)

Supports full duplex operation with IEEE

802.3x flow control and half duplex operation

with back-pressure flow control

Supports auto-polling function

Supports 10/100Mbps N-way Auto-negotiation

operation

Advanced Power Management features

Supports dynamic power management to

reduce power dissipation during idle or light

traffic period

Supports very low power Wake-On-LAN

(WOL) mode when the system enters sleep

mode and waits for network event to awake it

up. The wakeup events supported are network

link state change, receipt of a Magic Packet or

a pre-programmed Microsoft Wakeup Frame

or through GPIO pin

Supports Protocol Offload (ARP & NS) for

Windows 7 Networking Power Management

Supports complete I/O pins isolation during

WOL mode or Remote Wakeup Ready mode

to reduce leakage current on non-PCI and SPI

slave host interface

Supports optional EEPROM interface to store

MAC address

Supports up to four GPIOs and two of them

support Wake-On-LAN

Supports programmable LED pins for various

network

activity

indications

with

variable

voltage I/O and programmable driving strength

Integrates voltage regulator, 25MHz crystal

oscillator and power on reset circuit on chip

Supports optional clock output (25, 50, or

100MHz) for system use, if 25MHz crystal is

present

Supports alternative clock input (25MHz) from

system clock to save the 25MHz crystal cost

64-pin LQFP RoHS compliant package

Operates over 0 to +70C or -40 to +85C

temperature range
