Spartan-3A DSP FPGA Family:
Introduction and Ordering Information
Product Specification
Introduction
The Spartan®-3A DSP family of Field-Programmable Gate Arrays
(FPGAs) solves the design challenges in most high- volume,
cost-sensitive, high-performance DSP applications. The
two-member family offers densities ranging from 1.8 to 3.4 million
system gates, as shown in Table 1.
The Spartan-3A DSP family builds on the success of the
Spartan-3A FPGA family by increasing the amount of memory per
logic and adding XtremeDSP™ DSP48A slices. New features
improve system performance and reduce the cost of configuration.
These Spartan-3A DSP FPGA enhancements, combined with
proven 90 nm process technology, deliver more functionality and
bandwidth per dollar than ever before, setting the new standard in
the programmable logic and DSP processing industry.
The Spartan-3A DSP FPGAs extend and enhance the Spartan-3A
FPGA family. The XC3SD1800A and the XC3SD3400A devices
are tailored for DSP applications and have additional block RAM
and XtremeDSP DSP48A slices. The XtremeDSP DSP48A slices
replace the 18x18 multipliers found in the Spartan-3A devices and
are based on the DSP48 blocks found in the Virtex®-4 devices.
The block RAMs are also enhanced to run faster by adding an
output register. Both the block RAM and DSP48A slices in the
Spartan-3A DSP devices run at 250 MHz in the lowest cost,
standard -4 speed grade.
Because of their exceptional DSP price/performance ratio,
Spartan-3A DSP FPGAs are ideally suited to a wide range of
consumer electronics applications, such as broadband access,
home networking, display/projection, and digital television.
The Spartan-3A DSP family is a superior alternative to mask
programmed ASICs. FPGAs avoid the high initial cost, 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.
