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. Maximum DC overshoot (above V_CC) or undershoot (below GND) must be limited to either 0.5V or 10 mA, whichever is easier to achieve.
3. Maximum AC (during transitions) conditions are as follows; the device pins may undershoot to 2.0V or overshoot to +7.0V, provided this overshoot or undershoot lasts no more than 11 ns with a forcing current no greater than 100 mA.
4. For soldering guidelines, see the Package Infomation on the Xilinx website.

The Spartan™ and the Spartan-XL families XCS40 and XCS40XL are a high-vol- ume production FPGA solution that delivers all the key requirements for ASIC replacement up to 40,000 gates. These requirements include high performance, on-chip RAM, core solutions and prices that, in high volume, approach and in many cases are equivalent to mask pro- grammed ASIC devices.

The Spartan series XCS40 and XCS40XL is the result of more than 14 years of FPGA design experience and feedback from thousands of customers. By streamlining the Spartan series feature set, leveraging advanced process technologies and focusing on total cost management, the Spartan series delivers the key features required by ASIC and other high-volume logic users while avoiding the initial cost, long development cycles and inherent risk of conventional ASICs. The Spar-tan and Spartan-XL families in the Spartan series have ten members, as shown in Table 1.
