Introduction
The Spartan®-3E family of Field-Programmable Gate
Arrays (FPGAs) is specifically designed to meet the needs
of high volume, cost-sensitive consumer electronic applica-
tions. The five-member family offers densities ranging from
100,000 to 1.6 million system gates, as shown in Table 1.
-
-
622+ Mb/s data transfer rate per I/O
True LVDS, RSDS, mini-LVDS, differential
HSTL/SSTL differential I/O
Enhanced Double Data Rate (DDR) support
DDR SDRAM support up to 333 Mb/s
-
-
•
Abundant, flexible logic resources
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 config-
uration. These Spartan-3E FPGA enhancements, com-
bined with advanced 90 nm process technology, deliver
more functionality and bandwidth per dollar than was previ-
ously possible, setting new standards in the programmable
logic industry.
-
Densities up to 33,192 logic cells, including
optional shift register or distributed RAM support
Efficient wide multiplexers, wide logic
Fast look-ahead carry logic
Enhanced 18 x 18 multipliers with optional pipeline
IEEE 1149.1/1532 JTAG programming/debug port
-
-
-
-
•
•
Hierarchical SelectRAM™ memory architecture
-
-
Up to 648 Kbits of fast block RAM
Up to 231 Kbits of efficient distributed RAM
Because of their exceptionally low cost, Spartan-3E FPGAs
are ideally suited to a wide range of consumer electronics
applications, including broadband access, home network-
ing, display/projection, and digital television equipment.
Up to eight Digital Clock Managers (DCMs)
-
-
-
-
Clock skew elimination (delay locked loop)
Frequency synthesis, multiplication, division
High-resolution phase shifting
The Spartan-3E family is a superior alternative to mask pro-
grammed 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.
Wide frequency range (5 MHz to over 300 MHz)
•
•
Eight global clocks plus eight additional clocks per
each half of device, plus abundant low-skew routing
Configuration interface to industry-standard PROMs
