A54SX16A-2FG256I

Overview

The A54SX16A-2FGG256I is a Field Programmable Gate Array from the SX-A family, featuring 24,000 system gates and 1,452 logic modules. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology with a 256-pin Fine Pitch Ball Grid Array (FBGA) package. The device supports up to 180 user-programmable I/O pins and operates within an industrial temperature range of -40°C to +85°C. It delivers approximately 250 MHz system performance and 350 MHz internal clock frequencies.

Feature Summary

• Supports hot-swap compliant I/Os for safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• High-performance digital signal processing
• Industrial control systems requiring mixed-voltage I/O
• Secure embedded applications needing nonvolatile single-chip solutions

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm the specific ordering suffix matches the required speed grade and temperature range. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the supplier provides traceability documentation for critical deployments.

Selection Notes

Select this model when 24,000 system gates and 180 I/Os are sufficient for the design. The -2 speed grade offers approximately 25% faster performance than standard grades. Choose the FG package for high-density surface mount applications. Verify voltage compatibility for 2.5 V, 3.3 V, and 5 V mixed-operation environments.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are known for their low-power, high-performance capabilities using antifuse technology. The family ranges from 12,000 to 108,000 system gates, offering various package options including PQFP, TQFP, PBGA, and FBGA configurations for diverse design needs.

Replacement Considerations

Direct replacements may include other speed grades within the A54SX16A series, such as the standard or -1 variants, if performance margins allow. Package-compatible alternatives within the same gate count should be verified for pin-to-pin compatibility and electrical specifications before substitution.
