A54SX32A-1PQ208I

Overview

The A54SX32A-1PQ208I is an antifuse-based Field Programmable Gate Array (FPGA) from the Microchip SX-A family. It features 48,000 system gates and 2,880 configurable logic blocks (CLBs). The device provides up to 174 user-programmable I/Os within a 208-pin Plastic Quad Flat Pack (PQFP) package. It operates at a maximum system frequency of 250 MHz with internal performance reaching 350 MHz. The component supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains, ensuring compatibility with various interface standards.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing
• Deterministic timing through metal-to-metal interconnects and dedicated routing resources
• Integrated boundary-scan testing compliant with IEEE Standard 1149.1

Applications

• High-performance digital signal processing requiring deterministic latency
• Industrial control systems utilizing mixed-voltage I/O interfaces
• Prototyping complex logic designs replacing gate arrays or CPLDs
• Secure applications leveraging antifuse resistance to reverse engineering

Procurement Notes

Verify the specific ordering suffix to confirm the temperature grade and packaging compliance. The 'I' suffix indicates industrial temperature range availability. Confirm RoHS status as standard packaging may differ from lead-free variants. Ensure the datasheet version matches the manufacturing lot for accurate electrical specifications.

Selection Notes

Select this model when 48,000 system gates and 208 pins are required in a PQFP form factor. The '-1' speed grade offers approximately 15% faster performance than the standard grade. Verify that the design utilizes the available global clock networks and does not exceed the 2,880 CLB capacity. Consider thermal dissipation requirements for the PQFP package during high-frequency operation.

Part Context

This component belongs to the Actel SX-A family of FPGAs, now manufactured by Microchip Technology. The SX-A series utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. It is designed for low-power, high-density applications where nonvolatility and security are critical. The family includes devices ranging from 12,000 to 108,000 system gates.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade are limited due to the specific antifuse architecture. Review the SX-A product profile for alternative gate counts. Cross-family migration to newer Microchip FPGA families requires schematic and software redesign.
