XC3S250E-4VQG100I

Field Programmable Gate Array Overview

The XC3S250E-4VQG100I is a Field Programmable Gate Array from the AMD/Xilinx Spartan-3E family, housed in a VQFP-100 surface-mount package. It contains 5508 Logic Elements and 2448 Adaptive Logic Modules within 612 Configurable Logic Blocks. The device integrates 216 kbit of embedded block RAM and supports up to 66 I/O pins. Operating at a nominal 1.2 V supply voltage (range 1.14 V to 1.26 V), it achieves a maximum frequency of 300 MHz with a typical CLB combinatorial delay of 0.76 ns. It functions reliably across an industrial temperature range of -40°C to +100°C.

Field Programmable Gate Array Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or surplus channels. Ensure that any sourced units are genuine and match the specific suffix requirements for temperature grade and package type before integration into production designs.

Field Programmable Gate Array Selection Notes

Select this part when a moderate density FPGA with established reliability is required. The Spartan-3E series offers a balance of performance and cost for legacy designs. Verify that the 100-pin VQFP package fits the board space constraints and that the 300 MHz speed grade meets the timing requirements of the target application logic.

Field Programmable Gate Array Part Context

The XC3S250E-4VQG100I belongs to the Spartan-3E family, which succeeded the original Spartan-3 line. This generation introduced enhanced power management features and improved performance characteristics while maintaining compatibility with existing design tools. It represents a mature technology node widely used in various embedded applications prior to the introduction of newer Spartan-6 and Artix families.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements may not exist due to architectural differences. Consider migrating to the Spartan-6 or Artix-7 families for new designs, noting that these require retiming and potentially different pin assignments. Consult official migration guides for toolchain and design updates.
