A54SX32A-FG484I

Overview

The A54SX32A-FG484I is a Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and 2,880 logic modules (1,800 combinatorial cells and 1,080 dedicated flip-flops). The device supports up to 249 user-programmable I/O pins and features three global clock networks. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 484-pin Fine Pitch Ball Grid Array package with a 1.0 mm pitch.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes deterministic timing capabilities with 100% resource utilization and pin-locking support.
• Integrates boundary-scan testing compliance with IEEE Standard 1149.1 for diagnostic verification.

Applications

• 66 MHz PCI compliant interface designs
• High-performance state machines and fast counters
• Data path logic requiring deterministic timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the component matches the required speed grade for the target application timing constraints. Confirm RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this model when 48,000 system gates and 249 I/Os are required in a compact 484-pin footprint. Consider the industrial temperature grade (-40°C to +85°C) for environments exceeding commercial limits. Evaluate the antifuse architecture benefits for permanent configuration needs versus volatile FPGA alternatives.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilize metal-to-metal programmable antifuse interconnect elements. The family offers high performance with internal clock frequencies up to 350 MHz and supports various package options including PBGA and FBGA formats for different pin count requirements.

Replacement Considerations

Compatible devices within the same capacity include the A54SX32A-FBGG484I and A54SX32A-BG329I. Verify pin compatibility and thermal characteristics when substituting between FBGA and PBGA packages or changing speed grades.
