詳細說明

General Description The SMSC LAN91C111 is designed to facilitate the implementation of a third generation of Fast Ethernet connectivity solutions for embedded applications. For this third generation of products, flexibility and integration dominate the design requirements. The LAN91C111 is a mixed signal Analog/Digital device that implements the MAC and PHY portion of the CSMA/CD protocol at 10 and 100 Mbps. The design will also minimize data throughput constraints utilizing a 32-bit, 16-bit or 8-bit bus Host interface in embedded applications. The total internal memory FIFO buffer size is 8 Kbytes, which is the total chip storage for transmit and receive operations. The SMSC LAN91C111 is software compatible with the LAN9000 family of products.PRODUCT FEATURES „ Single Chip Ethernet Controller „ Dual Speed - 10/100 Mbps „ Fully Supports Full Duplex Switched Ethernet „ Supports Burst Data Transfer „ 8 Kbytes Internal Memory for Receive and Transmit FIFO Buffers „ Enhanced Power Management Features „ Optional Configuration via Serial EEPROM Interface „ Supports 8, 16 and 32 Bit CPU Accesses „ Internal 32 Bit Wide Data Path (Into Packet Buffer Memory) „ Built-in Transparent Arbitration for Slave Sequential Access Architecture „ Flat MMU Architecture with Symmetric Transmit and Receive Structures and Queues „ 3.3V Operation with 5V Tolerant IO Buffers (See Pin List Description for Additional Details) „ Single 25 MHz Reference Clock for Both PHY and MAC „ External 25Mhz-output pin for an external PHY supporting PHYs physical media. „ Low Power CMOS Design „ Supports Multiple Embedded Processor Host Interfaces —ARM —SH — Power PC — Coldfire — 680X0, 683XX — MIPS R3000 „ 3.3V MII (Media Independent Interface) MAC-PHY Interface Running at Nibble Rate „ MII Management Serial Interface „ 128-Pin QFP package; lead-free RoHS compliant package also available. „ 128-Pin TQFP package, 1.0 mm height; lead-free RoHS compliant package also available. „ Commercial Temperature Range from 0°C to 70°C (LAN91C111) „ Industrial Temperature Range from -40°C to 85°C (LAN91C111i)Network Interface „ Fully Integrated IEEE 802.3/802.3u-100Base-TX/10Base-T Physical Layer „ Auto Negotiation: 10/100, Full / Half Duplex „ On Chip Wave Shaping - No External Filters Required „ Adaptive Equalizer „ Baseline Wander Correction „ LED Outputs (User selectable – Up to 2 LED functions at one time) — Link — Activity — Full Duplex — 10/100 — Transmit — Receive
