A54SX16-2VQ100I

Overview

The A54SX16-2VQ100I is an antifuse-based Field Programmable Gate Array from the SX-A family, manufactured by Microsemi. It provides 24,000 system gates and 1,452 configurable logic blocks within a 100-pin VQFP package. The device supports up to 81 user-programmable I/O pins and operates at a maximum system frequency of 250 MHz with internal performance reaching 350 MHz. It utilizes 0.22 μm / 0.25 μm CMOS process technology and features nonvolatile configuration. The component supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os and includes hot-swap compliant inputs.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/O architecture allowing safe insertion into electrically active systems without degrading host reliability.
• Configurable I/O modules supporting multiple voltage standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2.
• Deterministic timing performance enabled by DirectConnect and FastConnect routing resources that minimize signal propagation delays.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• PCI-compliant interface designs requiring 66 MHz bus speeds
• Systems requiring deterministic timing and pin-locking capabilities

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as packaging options may vary. Check for product discontinuance notifications or lifecycle changes prior to procurement. Ensure design tools support the SX-A family architecture for successful programming.

Selection Notes

Select this device when 24,000 system gates and 1,452 CLBs are required in a compact 100-pin form factor. Choose the Industrial temperature grade variant if operation between -40°C and +85°C is necessary. Consider the speed grade '-2' for approximately 25% faster performance compared to standard speed devices. Verify I/O voltage requirements match the supported 2.5 V, 3.3 V, and 5 V mixed-voltage capabilities.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using antifuse technology. The family ranges from 12,000 to 108,000 system gates. The A54SX16A designation indicates the 24,000 gate capacity tier. The 'VQ' suffix typically denotes a Plastic Quad Flat Pack variant, though verification with the official datasheet is required for exact package dimensions.

Replacement Considerations

Direct replacements within the same family include other A54SX16 variants with different speed grades or packages, such as A54SX16-1TQ100I or A54SX16-2PQ208A. Cross-family migration to newer Microchip FPGA architectures may be necessary for long-term supply assurance due to the age of the SX-A line.
