Crystal LAN 10Base-T Embedded Ethernet Controller CS8900A
The CS8900A is a low-cost Ethernet LANĀ® controller for embedded applications. 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 patterns and available system resources. The result is increased system efficiency. The CS8900A is available in a 100-pin TQFP package, ideally suited for small form-factor, cost-sensitive Ethernet 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. Features Single-chip IEEE 802.3 ethernet solution Comprehensive suite of software drivers available Efficient packetPageā„¢ 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 and filters (polarity detection/correction ) AUI port for 10Base-2, 10Base-5 and 10Base-F Automatic re-transmission on collision, padding and CRC (cyclical redundancy check) 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 3 V or 5 V operation; commercial or industrial temperature range maximum at 5 V = 120 mA; typical at 5 V = 90 mA package: 100-pin TQFP; lead-free assembly
