Xilinx expands series Spartan-3A FPGA

Comparable to fairy and think in the company (Xilinx, Inc. (NASDAQ: XLNX) )Announce today, the small capsulation FPGA formal batch productino extending as the Spartan-3A FPGA series platform. These capsulate FPGA while offering breakthrough price small, to consumption, wired and wireless communication, network, industry and a lot of other responsive applications of cost, can reduce the overall cost of system greatly.

Except that it is available to capsulate more, Spartan-3A FPGA extended the platform but been offered from 50,000 to 3,400,000 systematic doors of more extensive device density ranges and power supervisory functions, can help designer try hard, reduce the intersection of components and parts and quantity at the circuit board and offer low cost complicated calculate and embedded handling capacity, thus reduce the system cost.

Spartan-3A series extend the platform and melt capsulation and Spartan-3A of miniature device, the low-cost and high-performance characteristic that Spartan-3A DSP and Spartan-3AN platform is proved by the market is in an organic whole, form a series of single, high-capacity FPGA platform. Rely on most extensive I/O standard to industry (26 kinds) Support, lasting disposing on functioning and advantages saves anti-cloning, the whole world employ the most extensive low cost FPGA to comparable to fairy series Spartan of thinking and already become at present. The accumulation camp of this line of products has charged and already exceeded 2,520 million dollars by the 1st quarter of 09 fiscal years.

Comparable to fairy and think of the products marketing director Patrick Dorsey in enormous quantities, low-cost of the company to represent: " It is a totally Integrated systematic platform that Spartan-3A extends the serial platforms, can help the sensitive applied customer of the cost to reduce the device quantity, save the expensive p-c board space, improve reliability, reduce and test the cost and raise operational capacities. It is a satisfied and extremely challenging cost goal, face the customer on market of a large number of application of consuming etc. to hope we offer a comprehensive platform, help them to introduce the products to the market fast with the low cost. Comparable to fairy to think of and meet this requirement now. "

Reduce the system cost

Compared with similar low cost FPGA solution, are comparable to fairy and think of Spartan-3A and extend FPGA solution reducibly and is up to 50% of the overall system cost. Integrating reducing the requirements for external components and parts of numerous system functions, have reduced the quiescent power drain and offered the stronger low-cost security system, this advantage is extremely attractive to system designer. Comparable to fairy and think of Spartan-3A device the low cost SRAM FPGA that is still the only built-in power management, offer required minimum the intersection of power and rail support at the same time ' Only there are two kinds of devices possessing these two conditions at the same time on the market) . The management mode of the duplicate supply can save the power consumption greatly, no longer need external devices such as the stabilizator, heat sink and dashpot,etc. at the same time. The reducible quiescent power drain up to 40% per cent of the standby mode is fast wake the ability simultaneously with system level up; In addition, adopt unique complete deenergization technology, the quiescent power drain under the dormancy mode is extremely low, is the electric current nearly up to 0? A.

Valid logic design of economy

It is series FPGA of only overall compatible SRAM and non-volatile FPGA that Spartan-3A extends the series, have offered the smooth staging route for non-volatile solution of the one piece. This serial devices have offered low cost FPGA user Shan Cun of the global maximum scale, and support many kinds of low-cost commercial flashing memory dispositions. In addition, this series have offered the abundant device to capsulate making up, most overall IP storehouse (twice of the proximate competition solution) And trigger price low until 39 have a match clever to think and third party develop board and develop kit only. The designer can reduce IP required time and expenses to develop oneself, can also get the pre- verification IP which needs less chip resources at the same time.

It is dealt with that it is complicated for the low cost to calculate and embedded

It has been offered the most high characteristic in all main low cost FPGA products that Spartan-3A extended the serial platforms. Whether this serial devices or an only sincere low-cost solution of mainstream of integrating the specialized DSP module. The realization scheme of adding the multiplier with logic gate is compared, logic resource service efficiencies are improved by 70% on average, meanwhile, it is achievable with ASIC equivalent characteristic not to need extra coprocessor chip either. The use match is efficacious to think of MicroBlaze? The processor, Extended Spartan-3A series offered overall Linux embeddedly to deal with supporting.

Price and supplying the situation

Offer whom new light capsulation choose have a match clever to think Spartan-3A it extends FPGA series devices to be already batch productino, can supply now. In the second half of 2009, it is lower than 1 dollar to order the initial unit price of one grade of XC3S50A devices of 500,000 VQ100 encapsulated minimum speeds in batches.
