CS8920A Datasheet PDF - Cirrus Logic

DESCRIPTION
The CS8920A is a low-cost Ethernet LAN Controller optimized for Industry Standard Architecture (ISA) Personal Computers. Its highly-integrated design eliminates the need for costly external components required by other Ethernet controllers.

FEATURES
■ Single-Chip IEEE 802.3 Ethernet Controller with Direct ISA-Bus Interface
■ Implements Industry-Standard Plug and Play
■ Full Duplex Operation
■ Auto-Negotiation of Full and Half duplex Modes
■ Recognizes Received Magic Packet™ Frames and Requests the Processor to Power Up
■ Supported by Complete Family of Device Drivers
■ Efficient PacketPage™ Architecture Operates in I/O and Memory Space, and as DMA Slave
■ On-Chip RAM Buffers Transmit & Receive Frames
■ 10BASE-T Port with Internal Analog Filters
■ AUI Port for 10BASE2, 10BASE5 and 10BASE-F
■ Programmable Receive Features:
    — StreamTransfer™ for Reduced CPU Overhead
    — Auto-Switch Between DMA and On-Chip Memory
    — Early Interrupts for Frame Pre-Processing
■ Four LED Drivers for Link Status, Full Duplex, and LAN Activity
■ Small 144-pin TQFP package, and minimal external components (transformer, crystal and optional EEPROM)
