About XA Spartan-3E FPGA
The XA Spartan-3E FPGA family meets the requirements of high-volume, cost-sensitive automotive electronics applications. The five devices in the series offer different densities and different package combinations from 100,000 to 1.6 million system gates. The XA device also offers extended temperature range Q-Grade (-40°C to +125°C Tj) and I-Grade (-40°C to +100°C Tj) devices and is compliant with the industry-recognized AEC-Q100 standard. These 90nm devices offer more functionality and I/O bandwidth in terms of unit cost per dollar compared to previous devices, setting new standards in the programmable logic industry. Due to its ultra-low cost, the XA Spartan-3E FPGA provides an excellent alternative solution that avoids the high mask cost and long development cycle of ASICs and ASSPs.
1. Spartan-3E FPGA Series
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 from 100,000 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, significant reducing the cost per logic cell New features improve system performance and reduce the cost of configuration.
These Spartan-3E 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
Existing ASICs. Also, FPGA programmability permits design upgrades in the field with no hardware replacement necessary, an impossibility with ASICs.
