Features
● High-performance non-PCI local bus
-- Supports 8/16-bit SRAM-like 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 multi-frames burst transfer mechanism to increase bulk DMA transfer size and reduce CPU loading due to frequent interrupts for short frame reception/transmission (US Patent Pending). The patented "short frame early dispatch timer" provides programmable delay for short packet transfer latency control. Supports padding bytes insertion between frames within a multi-frame burst for double word boundary alignment
-- 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 Quad-SPI or Dual-SPI flash memory interface for high performance applications
-- Supports RX Buffer Ring and TX Buffer Ring structure to receive or transmit or simultaneously receive and transmit packets from/to the MAC RX/TX packet buffer in burst transfer mode. Also supports multi-frames burst transfer mechanism to increase bulk DMA transfer size and reduce CPU loading due to frequent interrupts for short frame receive/transmission (US Patent Pending)
-- Supports Two-Port SPI interface to increase bandwidth
-- Supports optional Ready signal as flow control for SPI packet RX/TX
● Single-chip Fast Ethernet MAC/PHY controller
-- Embeds 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 (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 three Power Saving Modes during Ethernet cable unplug configured either by software or hardware automatically
● 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
