• Integrated JTAG boundary scan and full in-system programmability
• Supports multiple configuration modes including Master Serial and Slave Parallel

Field Programmable Gate Array Applications

• Portable consumer electronics requiring low power consumption
• Industrial control systems operating in extreme temperatures
• Battery-powered instrumentation and measurement devices
• Automotive infotainment and body control modules

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'AN' to confirm the low-power variant and extended temperature rating. Ensure the package type matches the 144-TQFP requirement. Check RoHS compliance status as manufacturing sources may vary. Confirm availability through authorized distributors given the component's age.

Field Programmable Gate Array Selection Notes

Select this model when design constraints require operation below standard commercial temperature limits or strict power budgets. Compare against standard Spartan-3A variants if thermal management is not a primary concern. Verify that the 144-pin footprint accommodates all necessary I/O signals without exceeding pin count limits.

Field Programmable Gate Array Part Context

This component belongs to the Spartan-3A family, which introduced enhanced low-power features compared to the original Spartan-3 series. It serves as a bridge between entry-level CPLDs and higher-performance FPGAs, offering a balance of logic density and energy efficiency for cost-sensitive embedded designs.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements are limited due to architectural differences. Consider the XC3S50-4TQG144C for standard temperature ranges or newer Artix-7 series for modern feature sets, though these require schematic and layout modifications.
