Xilinx公司的Spartan-3E系列FPGA有五个品种,容量从10万到160万系统门,采用先进的90nm工艺技术,具有MicroBlaze 和PicoBlaze嵌入处理器核,支持高达333Mbps的DDR SDRAM,特别适合大批量对成本敏感的消费类电子产品应用.
The Spartan®-3E family of Field-Programmable Gate Arrays (FPGAs) is specifically designed to meet the needs of high volume, cost-sensitive consumer electronic applications. The five-member family offers densities ranging from100,000 to 1.6 million system gates.
The Spartan-3E family builds on the success of the earlier Spartan-3 family by increasing the amount of logic per I/O, significantly reducing the cost per logic cell. New features
improve system performance and reduce the cost of configuration.
These Spartan-3E FPGA enhancements, combined with advanced 90 nm process technology, deliver more functionality and bandwidth per dollar than was previously
possible, setting new standards in the programmable logic industry.
Because of their exceptionally low cost, Spartan-3E FPGAs are ideally suited to a wide range of consumer electronics applications, including broadband access, home networking, display/projection, and digital television equipment.
The Spartan-3E family is a superior alternative to mask programmed ASICs. FPGAs avoid the high initial cost, the lengthy development cycles, and the inherent inflexibility of conventional ASICs. Also, FPGA programmability permits design upgrades in the field with no hardware replacement necessary, an impossibility with ASICs.
