XC3S50AN-5TQG144C

Field Programmable Gate Array Overview

XC3S50AN-5TQG144C is a low-power, SRAM-based Field Programmable Gate Array (FPGA) belonging to the Spartan-3A family. It features 50,000 system gates and 3,200 logic cells within a 144-pin Thin Quad Flat Package (TQFP). The device operates at a maximum frequency of 687 MHz under the -5 speed grade. Key internal resources include 18-kbit Block RAMs, Digital Clock Managers (DCMs), and dedicated multipliers for arithmetic operations. It utilizes a 90nm process technology with a 1.2V core voltage and supports multiple I/O standards.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix codes against official Xilinx documentation to confirm package type, temperature range, and industrial/commercial grading. Ensure compatibility with legacy design tools such as Xilinx ISE, as newer Vivado versions may have limited support for Spartan-3 devices. Confirm supply chain authenticity due to the component's age.

Field Programmable Gate Array Selection Notes

Select this model when moderate logic capacity is required alongside low power consumption. Compare against standard Spartan-3 variants if power efficiency is critical. Consider pin count limitations of the TQFP package relative to available I/O needs. Evaluate thermal dissipation capabilities inherent to the plastic quad flat package for enclosed environments.

Field Programmable Gate Array Part Context

The XC3S50AN belongs to the Spartan-3A Low Power family, an evolution of the original Spartan-3 series. This generation introduced reduced power consumption while maintaining similar resource densities. It serves as a bridge between entry-level CPLDs and higher-end FPGA families, targeting applications where power budget and board space are constrained but programmability is essential.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements within the same package are limited. Potential alternatives include other Spartan-3A or Spartan-3E devices with compatible gate counts, though I/O mapping and timing characteristics must be re-verified. Upgrading to Artix-7 or Kintex-7 requires significant schematic and constraint file modifications.
