A54SX16P-1VQ100M

Overview

The A54SX16P-1VQ100M 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 24,000 system gates and 1,452 configurable logic blocks (CLBs). The device supports a maximum internal clock frequency of 350 MHz with a typical system performance of 250 MHz. It features up to 81 user-programmable I/Os in a 100-pin Thin Quad Flat Pack (TQFP) package. The component operates at 2.5 V, 3.3 V, or 5 V with mixed-voltage support and includes dedicated flip-flops for sequential logic.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements.
• Features nonvolatile antifuse architecture that prevents reverse engineering and eliminates configuration bitstream interception.
• Provides deterministic timing through unique local routing resources including DirectConnect and FastConnect.
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).

Applications

• High-performance digital signal processing and control applications
• PCI-compliant interface designs requiring 66 MHz operation
• Secure embedded systems utilizing antifuse-based intellectual property protection

Procurement Notes

Verify the specific ordering suffix 'M' against official Microchip documentation to confirm military temperature grade availability. Confirm RoHS compliance status as standard packaging may differ from lead-free variants. Check current product lifecycle status as older FPGA families often face discontinuation.

Selection Notes

Select this model for designs requiring high-speed logic with deterministic timing characteristics. Ensure voltage levels match the 2.5 V, 3.3 V, or 5 V mixed-voltage capability. Verify pin count requirements align with the 100-pin TQFP package constraints and available I/O resources.

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 various gate counts ranging from 12,000 to 108,000 system gates across different device sizes, providing a scalable solution for low-power, high-performance designs.

Replacement Considerations

Consult official Microchip cross-reference guides for direct replacements. Consider newer Actel SmartFusion or IGLOO families for updated process technologies while maintaining functional compatibility.
