A54SX32-1PQ208I

Overview

The A54SX32-1PQ208I is a nonvolatile FPGA from the SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates, 1,452 logic modules, and 924 combinatorial cells. The device supports up to 174 user I/Os in a 208-pin PQFP package. It operates within an industrial temperature range of -40°C to +85°C. The part features three global clock networks and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Antifuse-based architecture providing permanent low-impedance connections with high security against reverse engineering
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Deterministic timing through segmented routing and dedicated local interconnect resources like DirectConnect
• Integrated boundary-scan testing (JTAG) for superior diagnostic and verification capabilities

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring hot-swappable interface capabilities
• Industrial applications needing robust nonvolatile programmable logic

Procurement Notes

Verify component authenticity through official Microchip Technology channels or authorized distributors. Confirm that the specific ordering suffix matches the required speed grade and temperature rating. Ensure compliance with relevant environmental regulations applicable to your region before procurement.

Selection Notes

Select this model when 48,000 system gates and 174 user I/Os are sufficient for the design. The -1 speed grade offers approximately 15% faster performance than standard grades. Verify that the 208-pin PQFP package fits the PCB layout constraints and thermal requirements of the target application.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes metal-to-metal antifuse technology. The family ranges from 12,000 to 108,000 system gates. The A54SX32 variant specifically targets designs needing moderate capacity with high-speed internal clocking capabilities up to 350 MHz.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A series, such as A54SX32-2PQ208I for higher performance or A54SX32-PQ208I for standard speed. Cross-family migration requires schematic and netlist adjustments.
