A54SX16P-VQ100

Overview

The A54SX16P-VQ100 is a Field Programmable Gate Array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 logic modules, including 924 combinatorial cells and 512 dedicated flip-flops. The device supports up to 81 user I/Os in a 100-pin Thin Quad Flat Pack (TQFP) package with a height of 1.4 mm. It operates at a maximum system frequency of 250 MHz and an internal clock frequency of 350 MHz. The component supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V, featuring hot-swap compliant I/Os and compliance with IEEE 1149.1 Boundary-Scan Testing.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.

Applications

• High-performance digital logic integration requiring nonvolatile single-chip solutions
• Systems requiring hot-swappable interface capabilities for maintenance or redundancy
• Applications needing secure FPGA implementation with protection against unauthorized access

Procurement Notes

Verify the specific ordering suffix 'V' corresponds to the intended temperature grade and packaging configuration. Confirm that the TQFP-100 package meets the mechanical constraints of the target PCB layout. Ensure compatibility with the Actel Designer software version required for programming the antifuse architecture.

Selection Notes

Select this model when 24,000 system gates and 81 I/Os are sufficient for the design complexity. Consider the 250 MHz system performance limit for timing closure. Verify that the 1.4 mm package height fits within the assembly clearance requirements. Check if the industrial or commercial temperature range matches the operational environment.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnect elements. The family offers high-density logic modules arranged in clusters and superclusters for optimal resource utilization. The SX-A series is known for its low-power consumption and high-speed performance relative to its gate count.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX16A series, such as A54SX16-1 or A54SX16-2, provided the timing requirements are met. Cross-family migration to newer Microchip FPGA architectures may require significant schematic and code redesign due to architectural differences.
