The Spartan®-IIE Field-Programmable Gate Array family
gives users high performance, abundant logic resources,
and a rich feature set, all at an exceptionally low price. The
seven-member family offers densities ranging from 50,000
to 600,000 system gates, as shown in Table 1. System performance
is supported beyond 200 MHz.
Features include block RAM (to 288K bits), distributed RAM
(to 221,184 bits), 19 selectable I/O standards, and four
DLLs (Delay-Locked Loops). Fast, predictable interconnect
means that successive design iterations continue to meet
The Spartan-IIE 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).
