Spartan-3ANFPGAintegrated SPI FlashFTG256industrial gradenonvolatile FPGA

XC3S400AN-4FTG256I is an industrial-grade Spartan-3AN FPGA combining programmable logic with integrated SPI Flash for configuration and nonvolatile data storage.

Best for

  • Systems needing integrated FPGA configuration Flash
  • Industrial FPGA designs requiring up to 195 user I/Os
  • Embedded designs using block RAM, multipliers, and DCMs

Avoid if

  • A current-generation FPGA ecosystem or long-term supply assurance is mandatory
  • The design needs interfaces or resources beyond Spartan-3AN capabilities

Check before use

  • Verify exact package availability and date-code requirements
  • Confirm configuration bitstream and user Flash memory allocation
  • Run static timing analysis using the applicable production speed file
