A54SX08A-FPQ208

Overview

The A54SX08A-FPQ208 is a nonvolatile FPGA from the SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 system gates, 768 logic modules (comprising 512 combinatorial cells and 256 dedicated flip-flops), and supports up to 130 user-programmable I/Os. The device operates with supply voltages of 2.5 V, 3.3 V, or 5 V, enabling mixed-voltage operation with 5 V input tolerance. It features three global clock networks and supports hot-swap capabilities for most I/O standards.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V drive strength and input tolerance.
• Features hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements.
• Includes individually configurable weak-resistor pull-up or pull-down states for deterministic power-up behavior.
• Provides boundary-scan testing compliance with IEEE Standard 1149.1 via JTAG interface.

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and packaging compliance. The 'F' speed grade indicates performance approximately 40% slower than standard. Confirm RoHS status and lead-free packaging details if required by local regulations. Ensure the component matches the exact pin count and package type specified in the design schematic.

Selection Notes

Select this model when 12,000 system gates are sufficient for the target logic density. The -F speed grade is appropriate for designs where timing margins allow for slower propagation delays compared to standard or faster grades. Verify that the PQFP-208 package fits the available PCB real estate and thermal constraints. Consider the availability of global clocks and I/O flexibility for complex interface requirements.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal programmable antifuse interconnect elements. The architecture employs a sea-of-modules design with register cells and combinatorial cells arranged in clusters. This family was acquired by Microsemi Corporation, which continues to support these devices as part of its high-reliability semiconductor portfolio.

Replacement Considerations

Compatible substitutes within the same family include the A54SX08A-1PQ208I and A54SX08A-2PQ208I, which offer faster speed grades. Devices with higher capacity such as the A54SX16A-PQ208 may serve as upward replacements if additional logic resources are needed. Ensure any replacement maintains the PQFP-208 package footprint and compatible voltage levels.
