A54SX08-VQG100

Overview

The A54SX08-VQG100 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 12,000 system gates, 768 combinatorial cells, and up to 512 dedicated flip-flops. The device supports mixed-voltage I/O operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It features hot-swap compliant I/Os (excluding 3.3 V PCI), deterministic timing, and boundary-scan testing compliance with IEEE Standard 1149.1. The part is housed in a 100-pin Thin Quad Flat Pack package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage I/O standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2 with individually configurable slew rates.
• Hot-swap compliant I/Os allow insertion into electrically active systems without degrading host reliability or requiring supply voltage sequencing.
• Includes unique in-system diagnostic capabilities via Silicon Explorer II and boundary-scan testing compliant with IEEE Standard 1149.1.

Applications

• Low-power, high-performance designs requiring nonvolatile configuration
• Systems requiring hot-swappable interface capabilities
• Applications needing mixed-voltage I/O interfacing

Procurement Notes

Verify the specific speed grade suffix associated with the VQG100 package designation against official Actel ordering guides, as standard speed grades may vary. Confirm temperature range availability (Commercial, Industrial, Automotive, or Military) matches project requirements. Ensure design tools support the SX-A architecture for proper place-and-route implementation.

Selection Notes

Select this device for applications requiring 12,000 system gates with deterministic performance. Consider the A54SX08A variants if higher speed grades or different package options are needed. Verify that the 100-pin TQFP footprint fits the PCB layout constraints. Check if the available user I/O count of 81 pins meets interface requirements.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which offers a cost-effective platform for integrating complex logic functions. The family utilizes antifuse technology to provide security against reverse engineering and eliminates the need for external configuration memory. The SX-A series is designed to replace multiple CPLDs or gate arrays in various digital logic applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided datasheet. Designers should consult Actel sales representatives for current availability and potential cross-references within the SX-A product line or newer Microchip FPGA families.
