A54SX16A-TQ100I

Overview

The A54SX16A-TQ100I is a Field Programmable Gate Array from the SX-A family, featuring 24,000 system gates and 1,452 logic modules. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 100-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 81 user-programmable I/O pins and includes dedicated flip-flops for sequential logic implementation.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without damage
• Provides power-up/down friendly operation with no sequencing required for supply voltages
• Includes nonvolatile single-chip solution architecture preventing reverse engineering via FuseLock technology

Applications

• Industrial control systems requiring deterministic timing
• Hot-swappable peripheral interface designs
• Secure embedded logic applications protected against design theft

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the package type corresponds to the 100-pin TQFP form factor. Ensure the speed grade matches the standard performance requirements for the target application frequency.

Selection Notes

Select this component when 24,000 system gates are sufficient for the design complexity. Consider the 100-pin TQFP package constraints for PCB layout. Verify that the 81 available I/O pins meet the interface requirements. Check if the standard speed grade meets the maximum clock frequency needs.

Part Context

This part belongs to the Actel SX-A family of antifuse FPGAs. It shares architectural features like DirectConnect and FastConnect routing with other devices in the series. The A54SX16A variant specifically offers a balance between gate density and pin count compared to smaller or larger siblings.

Replacement Considerations

Direct replacements include other A54SX16A variants with different packages or temperature grades. Cross-family migration may require significant redesign due to architectural differences.
