A54SX32A-FTQG100

Overview

The A54SX32A-FTQG100 is a Field Programmable Gate Array from the Microchip Technology SX-A family, featuring 48,000 system gates. It utilizes antifuse technology and supports mixed-voltage I/O operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. The device provides up to 81 user-programmable I/O pins and includes three global clock networks. It operates within a commercial temperature range of 0°C to +70°C and is housed in a 100-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Antifuse-based nonvolatile architecture providing deterministic timing and high security against reverse engineering
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Configurable logic modules with DirectConnect and FastConnect routing for predictable signal propagation
• Integrated Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 (JTAG)

Applications

• High-performance digital logic integration replacing complex CPLDs
• Systems requiring hot-swappable interface capabilities
• Secure embedded designs utilizing antifuse technology for IP protection

Procurement Notes

Verify the specific speed grade suffix associated with the FTQG100 designation, as standard ordering typically uses PQ, TQ, BG, or FG prefixes. Confirm RoHS compliance status and lead-free packaging availability through official Microchip distributors. Ensure design files account for the commercial temperature grade limitations during procurement planning.

Selection Notes

Select this component when 48,000 system gates and 81 I/Os are required in a compact 100-pin form factor. Consider the SX-A family for applications needing mixed-voltage I/O support and hot-swap functionality. Evaluate the -F speed grade if lower performance than standard is acceptable for cost optimization.

Part Context

This part belongs to the Actel SX-A FPGA family, characterized by metal-to-metal programmable antifuse interconnects. The SX-A series offers a sea-of-modules architecture with dedicated R-cells and C-cells. The FTQG100 variant specifically denotes a Thin Quad Flat Pack package with a slower speed grade compared to standard offerings.

Replacement Considerations

Direct pin-compatible replacements within the same package and gate count may be limited due to discontinued speed grades. Check for updated Microchip SX-A variants with compatible I/O counts and voltage levels. Verify thermal characteristics and software toolchain compatibility before substitution.
