A54SX16-1VQG100I

Overview

The A54SX16-1VQG100I is an antifuse-based Field Programmable Gate Array from the Actel SX-A family, manufactured by Microsemi Corporation. It provides 24,000 system gates and supports up to 81 user I/Os within a 100-pin Thin Quad Flat Pack (TQFP) package. The device operates at a maximum system frequency of 250 MHz with internal performance reaching 350 MHz. It features mixed-voltage I/O support for 2.5 V, 3.3 V, and 5 V levels, ensuring compatibility with various logic standards. The Industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Supports hot-swap capabilities for safe insertion into active systems without power sequencing requirements.
• Features nonvolatile antifuse technology that prevents reverse engineering and design theft through FuseLock security.
• Includes boundary-scan testing compliant with IEEE Standard 1149.1 for enhanced diagnostic and verification.

Applications

• High-performance digital signal processing
• PCI-compliant interface designs
• Secure embedded control systems

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to potential counterfeit risks. Confirm RoHS compliance status as packaging suffixes may vary. Check for end-of-life notifications or production change notices affecting availability. Ensure proper ESD handling during storage and installation.

Selection Notes

Select this model for applications requiring deterministic timing and high-speed logic integration. Consider the TQFP-100 package constraints for PCB layout. Evaluate thermal dissipation requirements for industrial temperature ranges. Compare against standard speed grades if lower performance suffices for cost reduction.

Part Context

This component belongs to the Actel SX-A family of FPGAs, known for low-power and high-performance characteristics. The SX-A series utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. It serves as a single-chip solution for integrating complex logic functions previously requiring multiple CPLDs or gate arrays.

Replacement Considerations

Direct replacements include other A54SX16 variants with different speed grades or packages, such as A54SX16A-1TQ100I. Verify pinout compatibility and electrical specifications before substitution. Consult Microchip documentation for updated family alternatives if discontinuation occurs.
