CS8900A Product Data Sheet FEATURES Crystal LAN Ethernet Single-Chip IEEE 802.3 Ethernet Controller with Controller Direct ISA-Bus Interface Maximum Current Consumption = 55 mA (5V DESCRIPTION Supply) The CS8900A is a low-cost Ethernet LAN Controller op- 3V or 5V Operation timized for the Industry Standard Architecture (ISA) bus Industrial Temperature Range and general purpose microcontroller busses. Its highly- Comprehensive Suite of Software Drivers integrated design eliminates the need for costly external Available components required by other Ethernet controllers. The CS8900A includes on-chip RAM, 10BASE-T transmit Efficient PacketPage Architecture Operates in I/O and Memory Space, and as DMA Slave and receive filters, and a direct ISA-Bus interface with 24 mA Drivers. Full Duplex Operation In addition to high integration, the CS8900A offers a On-Chip RAM Buffers Transmit and Receive Frames broad range of performance features and configura- tionoptions. Its unique PacketPage architecture 10BASE-T Port with Analog Filters, Provides: automatically adapts to changing network traffic pat- - Automatic Polarity Detection and Correction terns and available system resources. The result is AUI Port for 10BASE2, 10BASE5 and 10BASE-F increased system efficiency. Programmable Transmit Features: The CS8900A is available in a 100-pin LQFP package - Automatic Re-transmission on Collision ideally suited for small form-factor, cost-sensitive Ether- - Automatic Padding and CRC Generation net applications. With the CS8900A, system engineers can design a complete Ethernet circuit that occupies Programmable Receive Features: less than 1.5 square inches (10 sq. cm) of board space. - Stream Transfer for Reduced CPU Overhead - Auto-Switch Between DMA and On-Chip Memory ORDERING INFORMATION - Early Interrupts for Frame Pre-Processing - Automatic Rejection of Erroneous Packets CS8900A-CQZ 0 to 70 C 5V
