1 / 138 page Copyright © Cirrus Logic, Inc. 2007 (All Rights Reserved) CS8900A Product Data Sheet Crystal LAN™ Ethernet Controller FEATURES Single-Chip IEEE 802.3 Ethernet Controller with Direct ISA-Bus Interface Maximum Current Consumption = 55 mA (5V Supply) 3V or 5V Operation Industrial Temperature Range Comprehensive Suite of Software Drivers Available Efficient PacketPage™ Architecture Operates in I/O and Memory Space, and as DMA Slave Full Duplex Operation On-Chip RAM Buffers Transmit and Receive Frames 10BASE-T Port with Analog Filters, Provides: - Automatic Polarity Detection and Correction AUI Port for 10BASE2, 10BASE5 and 10BASE-F Programmable Transmit Features: - Automatic Re-transmission on Collision - Automatic Padding and CRC Generation Programmable Receive Features: - Stream Transfer™ for Reduced CPU Overhead - Auto-Switch Between DMA and On-Chip Memory - Early Interrupts for Frame Pre-Processing - Automatic Rejection of Erroneous Packets EEPROM Support for Jumperless Configuration Boot PROM Support for Diskless Systems Boundary Scan and Loopback Test LED Drivers for Link Status and LAN Activity Standby and Suspend Sleep Modes DESCRIPTION The CS8900A is a low-cost Ethernet LAN Controller op- timized for the Industry Standard Architecture (ISA) bus and general purpose microcontroller busses. Its highly- integrated design eliminates the need for costly external components required by other Ethernet controllers. The CS8900A includes on-chip RAM, 10BASE-T transmit and receive filters, and a direct ISA-Bus interface with 24 mA Drivers. In addition to high integration, the CS8900A offers a broad range of performance features and configuration- options. Its unique PacketPage architecture automatically adapts to changing network traffic pat- terns and available system resources. The result is increased system efficiency. The CS8900A is available in a 100-pin LQFP package ideally suited for small form-factor, cost-sensitive Ether- net applications. With the CS8900A, system engineers can design a complete Ethernet circuit that occupies less than 1.5 square inches (10 sq. cm) of board space.
