Introduction
The Spartan™-IIE 1.8V Field-Programmable Gate Array family gives users high performance, abundant logic resources, and a rich feature set, all at an exceptionally low price. The five-member family offers densities ranging from 50,000 to 300,000 system gates, as shown in Table 1. System performance is supported beyond 200 MHz.
Spartan-IIE devices deliver more gates, I/Os, and features per dollar than other FPGAs by combining advanced process technology with a streamlined architecture based on the proven Virtex™-E platform. Features include block RAM (to 64K bits), distributed RAM (to 98,304 bits), 19 selectable I/O standards, and four DLLs (Delay-Locked Loops). Fast, predictable interconnect means that successive design iterations continue to meet timing requirements.
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).
