XC3S50A-5TQG144C

Field Programmable Gate Array Overview

The XC3S50A-5TQG144C is a field-programmable gate array (FPGA) belonging to the AMD Spartan-3A family, manufactured using a 90 nm process technology. It features 176 logic array blocks and approximately 1,584 logic elements, providing sufficient capacity for embedded control and interface applications. The device includes 55296 bits of on-chip RAM and supports up to 108 user I/O pins. It operates within a core voltage range of 1.14 V to 1.26 V and is rated for an industrial temperature range of -40°C to +100°C TJ. The component is housed in a 144-pin TQFP package with a 20x20 mm footprint.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix codes against official AMD documentation to confirm exact speed grades and temperature ratings. Ensure compatibility with legacy design tools such as Xilinx ISE, as newer Vivado versions may have limited support for this older FPGA family. Confirm package dimensions and pinout details prior to PCB layout finalization.

Field Programmable Gate Array Selection Notes

Select this model when moderate logic density and cost-effectiveness are prioritized over high-performance computing. Compare resource utilization against larger Spartan-3A variants if additional logic or memory is required. Consider the TQFP package constraints regarding thermal dissipation and manual assembly feasibility compared to BGA alternatives.

Field Programmable Gate Array Part Context

This component is part of the Spartan-3A family, which succeeded the original Spartan-3 series by offering enhanced I/O capabilities and lower power consumption while maintaining compatibility with existing design flows. It targets cost-sensitive markets requiring flexible programmability for interface and control tasks without the complexity of higher-end Virtex or Kintex devices.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements within the same package and speed grade should be verified via AMD's official cross-reference guides. Upgrades may involve migrating to newer families like Artix-7, which requires significant schematic and software toolchain adjustments due to architectural differences.
