Introduction
The Spartan
-II 2.5V Field-Programmable Gate Array fam-
ily gives users high performance, abundant logic resources,
and a rich feature set, all at an exceptionally low price. The
six-member family offers densities ranging from 15,000 to
200,000 system gates, as shown in
Table 1
. System perfor-
mance is supported up to 200 MHz.
Spartan-II devices deliver more gates, I/Os, and features
per dollar than other FPGAs by combining advanced pro-
cess technology with a streamlined Virtex-based architec-
ture. Features include block RAM (to 56K bits), distributed
RAM (to 75,264 bits), 16 selectable I/O standards, and four
DLLs. Fast, predictable interconnect means that successive
design iterations continue to meet timing requirements.
The Spartan-II family is a superior alternative to
mask-programmed ASICs. The FPGA avoids the initial cost,
lengthy development cycles, and inherent risk of
conventional ASICs. Also, FPGA programmability permits
design upgrades in the field with no hardware replacement
necessary (impossible with ASICs).
