A54SX08-VQG100I

Overview

The A54SX08-VQG100I is an industrial-grade Field Programmable Gate Array from the Actel SX-A family, featuring 12,000 system gates and fabricated on 0.22 μm/0.25 μm CMOS antifuse technology. It utilizes a Plastic Quad Flat Pack (PQFP) package with 100 pins, supporting up to 81 user I/Os. The device operates within an industrial temperature range of -40°C to +85°C and includes three global clock networks. Key specifications include 768 combinatorial cells, 512 dedicated flip-flops, and support for mixed-voltage I/O standards including 3.3V PCI, 5V TTL, and 2.5V LVCMOS.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Hot-swap compliant I/O architecture allowing safe insertion into active systems with tristated outputs during power-up/down sequences.
• Deterministic timing performance enabled by DirectConnect and FastConnect routing resources that minimize signal propagation delays.
• Integrated security features via FuseLock technology preventing reverse engineering and unauthorized design access.

Applications

• Industrial control systems requiring deterministic logic processing and robust environmental tolerance.
• Embedded applications needing nonvolatile configuration with reduced board space and component count.
• Systems requiring hot-swappable interface capabilities for high availability and maintenance flexibility.
• Prototyping and low-volume production designs leveraging antifuse technology for fixed-function reliability.

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'VQG' denotes the 100-pin PQFP package. Confirm RoHS compliance status if required, as standard packaging may differ from lead-free variants. Ensure the source document matches the current datasheet version to validate pin assignments and electrical characteristics against legacy revisions.

Selection Notes

Select this device when 12,000 system gates are sufficient for the target logic density. Consider the PQFP package only if surface mount constraints allow for its footprint. Evaluate the need for industrial temperature rating versus commercial options. Verify that the available 81 user I/Os meet interface requirements and that the speed grade aligns with the maximum internal clock frequency needs of the application.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are distinguished by their use of antifuse technology rather than volatile SRAM or flash configuration memories. The family ranges from 12,000 to 108,000 system gates, offering varying levels of logic resources and I/O counts. The SX-A series is designed for applications prioritizing security, nonvolatility, and deterministic performance over reprogrammability.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Designers should consult Microchip's official obsolescence notices or cross-reference tools for equivalent devices within the same antifuse FPGA portfolio or alternative nonvolatile FPGA families.
