XC3SD3400A-4CSG484LI

XC3SD3400A-4CSG484LI is a Xilinx Spartan-3S FPGA device. It targets low-cost, mid-range digital designs and comes in a 484-ball CSBGA package with RoHS-compliant (lead-free) packaging. The -4 speed grade indicates a slower-speed device within the family. The “3400A” roughly reflects about 3,400 logic cells (approximately CLBs with LUTs), plus embedded resources such as Block RAM and DSP slices, organized across multiple I/O banks. It includes clock-management features (PLLs) and support for various I/O standards.
Typical use cases: glue logic, DSP preprocessing, embedded interfaces, and small-to-mid-size prototyping.
Tooling: Xilinx ISE (older flows) and related design utilities are used for Spartan-3S devices; newer tools may drop support.
Notes: This is an older FPGA family. For new designs, consider newer Xilinx families. For exact specs (logic cell count, RAM and DSP resources, I/O count, voltage, and package pinout), consult the official XC3SD3400A-4CSG484LI datasheet and package overview from Xilinx.
