CS8900ACrystal LANTM Ethernet Controller2PI271PP2OVERVIEW (Continued from Page 1)sonal Computers. Its highly-integrated designeliminates the need for costly external componentsrequired by other Ethernet controllers. TheCS8900A includes on-chip RAM, 10BASE-T trans-mit and receive filters, and a direct Bus interfacewith 24 mA Drivers.In addition to high integration, the CS8900A offersa broad range of performance features and config-uration options. Its unique PacketPage architec-ture automatically adapts to changing networktraffic patterns and available system resources.The result is increased system efficiency. TheCS8900A is available in a 100-pin TQFP packageideally suited for small form-factor, cost-sensitiveEthernet applications. With the CS8900A, systemengineers can design a complete Ethernet circuitthat occupies less than 1.5 square inches (10 sq.cm)ofboardspace.Contacting Cirrus Logic SupportFor a complete listing of Direct Sales, Distributor, and Sales Representative contacts, visit the Cirrus Logic web site at:http://www.cirrus.com/corporate/contacts/Preliminary product information describes products which are in production, but for which full characterization data is not yet available.

CS8900ACrystal LANTM Ethernet Controller3PI271PP2OVERVIEW (cont.)CONFIDENTIAL DRAFTKey BenefitsVery Low CostThe CS8900A is designed to provide the lowest-cost Ethernet solution available for embeddedapplications, portable motherboards, and adaptercards. Cost-saving features include:•Integrated RAM eliminates the need for expensiveexternal memory chips.•On-chip 10BASE-T filters allow designers to usesimple isolation transformers instead of morecostly filter/transformer packages.•The serial EEPROM port, used for configurationand initialization, eliminates the need for expen-sive switches and jumpers.•The CS8900A is designed to be used on a 2-layercircuit board instead of a more expensive multi-layer board.•The 8900A-based solution offers the smallestfootprint available, saving valuable printed circuitboard area.•A set of certified software drivers is available at nocharge, eliminating the need for costly softwaredevelopment.High PerformanceThe CS8900A is a full 16-bit Ethernet controllerdesigned to provide optimal system performanceby minimizing time on the bus and CPU overheadper frame. It offers equal or superior performancefor less money when compared to other Ethernetcontrollers. The CS8900A’s PacketPage architec-ture allows software to select whichever accessmethod is best suited to each particular CPU/busconfiguration. When compared to older I/O-spacedesigns, PacketPage is faster, simpler and moreefficient.To boost performance further, the CS8900Aincludes several key features that increasethroughput and lower CPU overhead, including:•StreamTransfer cuts up to 87% of interrupts to thehost CPU during large block transfers.•Auto-Switch DMA allows the CS8900A to maxi-mize throughput while minimizing missed frames.•Early interrupts allow the host to preprocessincoming frames.•On-chip buffering of full frames cuts the amountof host bandwidth needed to manage Ethernettraffic.Low Power and Low NoiseFor low power needs, the CS8900A offers threepower-down options: Hardware Standby, Hard-ware Suspend, and Software Suspend. In Standbymode, the chip is powered down with the exceptionof the 10BASE-T receiver, which is enabled to lis-ten for link activity. In either Hardware or SoftwareSuspend mode, the receiver is disabled and powerconsumption drops to the micro-ampere range.In addition, the CS8900A has been designed forvery low noise emission, thus shortening the timerequired for EMI testing and qualification.Complete SupportThe CS8900A comes with a suite of software driv-ers for immediate use with most industry standardnetwork operating systems. In addition, completeevaluation kits and manufacturing packages areavailable, significantly reducing the cost and timerequired to produce new Ethernet products.Ordering InformationCS8900A-CQ, 0° to 70° C, 100-pin TQFPCS8900A-IQ, -40° to 85° C, 100-pin TQFPCS8900A-CQ, 30° to 70° C, 100-pin TQFPCRD8900A-1 Evaluation KitIf you have any questions, please contact theundersigned by phone or by email.www.cirrus.com/support/ or Field ApplicationsEngineers.
