A54SX08A-1PQG208I

Overview

The A54SX08A-1PQG208I is an industrial-grade Field Programmable Gate Array from the Actel SX-A family, housed in a 208-pin Plastic Quad Flat Pack. It provides 12,000 system gates and supports up to 130 user I/Os. The device operates within an industrial temperature range of -40°C to +85°C and features a speed grade of -1, offering approximately 15% faster performance than standard speed. Fabricated on 0.22 μm/0.25 μm CMOS antifuse technology, it delivers deterministic timing with up to 768 combinatorial cells and 512 dedicated flip-flops.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports mixed-voltage I/O operation including 2.5 V, 3.3 V, and 5 V standards with 5 V input tolerance and drive strength.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability or requiring supply voltage sequencing.
• Includes Boundary-Scan Testing compliance with IEEE Standard 1149.1 (JTAG) for superior diagnostic and verification capabilities.

Applications

• Industrial control systems requiring deterministic timing and robust I/O interfaces
• Embedded logic integration replacing complex programmable logic devices
• Systems requiring hot-swappable functionality and power-up/down flexibility

Procurement Notes

Verify the specific ordering suffix G for RoHS compliant packaging if required by environmental regulations. Confirm the package type PQFP matches the target PCB footprint. Ensure the temperature grade I corresponds to the operational environment requirements. Cross-reference the speed grade -1 against design timing constraints to ensure adequate performance margins.

Selection Notes

Select this component when a nonvolatile FPGA architecture is preferred over volatile SRAM-based alternatives to eliminate configuration boot times. Consider the A54SX08A for designs requiring moderate logic density with high pin counts. Evaluate the -1 speed grade if slightly higher performance is needed compared to standard speed without moving to more expensive grades. Verify that the 208-pin PQFP package fits the available board space and assembly capabilities.
