XC3S50-4PQG208I

Field Programmable Gate Array Overview

The XC3S50-4PQG208I is a Field Programmable Gate Array (FPGA) belonging to the Spartan-3 family manufactured by AMD Xilinx. It features 50,000 system gates and utilizes a 90nm process technology. The device operates within a commercial temperature range of 0°C to 70°C, indicated by the 'C' suffix in its variant classification, though the specific part number denotes the -4 speed grade. It is housed in a 208-pin Plastic Quad Flat Package (PQFP) with a 14mm body size. The architecture includes embedded memory blocks and supports standard I/O interfaces for digital logic implementation.

Field Programmable Gate Array Feature Summary

• Supports complex digital logic design through reconfigurable programmable fabric
• Integrates dedicated block RAM resources for data storage and buffering
• Provides multiple general-purpose input/output pins for peripheral connectivity

Field Programmable Gate Array Applications

• Industrial control systems requiring moderate logic density
• Consumer electronics logic interfacing
• Automotive auxiliary control modules

Field Programmable Gate Array Procurement Notes

Verify the exact speed grade and package type against the original design specifications before procurement. Confirm that the component meets the required thermal operating conditions for the target environment. Ensure compatibility with existing programming tools and bitstream formats used in the current production workflow.

Field Programmable Gate Array Selection Notes

Select this component when the design requires approximately 50,000 gates and a PQFP-208 footprint. Compare against other Spartan-3 variants if higher pin counts or different package styles are needed. Consider the -4 speed grade timing constraints relative to the maximum clock frequency requirements of the application logic.

Field Programmable Gate Array Part Context

This part belongs to the Spartan-3 FPGA family, which serves as an entry-level solution for cost-sensitive applications. It bridges the gap between simple CPLDs and high-end Virtex devices. The family is known for providing a balance of performance, power consumption, and ease of use for standard logic applications.

Field Programmable Gate Array Replacement Considerations

Direct replacements may include other Spartan-3 models with compatible gate counts but different packages, such as XC3S50-4VQ100I. Verify pin-to-pin compatibility if physical board space is constrained. Cross-reference with newer families like Spartan-6 only if architectural migration is planned.
