Notes:
1. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions is not implied. Exposure to
Absolute Maximum Ratings conditions for extended periods of time may affect device reliability.
2. VIN should not exceed V_CCO by more than 3.6V over extended periods of time (e.g., longer than a day).
3. Maximum DC overshoot must be limited to either V_CCO + 0.5V or 10 mA, and undershoot must be limited to 0.5V or 10 mA, whichever is easier to achieve. The Maximum AC conditions are as follows: The device pins may undershoot to 2.0V or overshoot to V_CCO + 2.0V, provided this over/undershoot lasts no more than 11 ns with a forcing current no greater than 100 mA.
4. For soldering guidelines, see the Packaging Information on the Xilinx Web site.

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 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.

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 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 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).
