A54SX32-2PQG208I

Overview

The A54SX32-2PQG208I is an antifuse-based Field Programmable Gate Array from the Microchip SX-A family. It provides 48,000 system gates and 1,452 logic modules within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device supports up to 174 user-programmable I/O pins and features three global clock networks. Operating at speed grade -2, it delivers approximately 25% faster performance than standard grades with a maximum internal frequency of 350 MHz. It utilizes 0.22/0.25 μm CMOS technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnects for permanent configuration without external memory.
• Supports hot-swap capabilities and power-up/down friendly operation allowing supply voltages to be powered in any order without sequencing requirements.
• Features deterministic timing through patented DirectConnect and FastConnect routing resources that minimize signal propagation delays.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and unauthorized design access.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• Systems requiring deterministic timing and fast state machine execution
• Applications necessitating nonvolatile configuration without boot-time bitstream loading

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm RoHS compliance status as packaging suffixes may vary. Check for end-of-life notifications or production discontinuation notices prior to procurement. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the datasheet.

Selection Notes

Select this model when 48,000 system gates and 174 I/Os are required in a PQFP-208 package. Choose speed grade -2 for designs needing approximately 25% higher performance than standard grades. Verify voltage compatibility for 2.5 V, 3.3 V, and 5 I/O interfaces. Consider thermal dissipation characteristics inherent to the PQFP package for PCB layout planning.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their antifuse technology and high-speed performance. The family includes devices ranging from 12,000 to 108,000 system gates. The A54SX32 variant specifically targets mid-range complexity applications requiring robust I/O flexibility and secure, nonvolatile programming.

Replacement Considerations

Direct pin-compatible replacements within the same package and capacity are limited due to the specific antifuse architecture. Review other SX-A family members like A54SX32A for updated specifications. Evaluate migration to modern Microchip FPGA families if current production availability is critical.
