A54SX32-1PQ208

Overview

The A54SX32-1PQ208 is a nonvolatile Field Programmable Gate Array (FPGA) from the Microchip Technology SX-A family, utilizing antifuse technology. It features 48,000 system gates and 1,452 configurable logic blocks (CLBs). The device operates within a supply voltage range of 2.25V to 5.25V and supports up to 174 user-programmable I/O pins in its 208-pin Plastic Quad Flat Pack (PQFP) package. Designed for high performance, it achieves internal clock frequencies up to 350 MHz and system performance up to 250 MHz. The component includes three global clock networks and complies with IEEE 1149.1 Boundary-Scan Testing standards.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements that form permanent low-impedance connections upon programming.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength capabilities.
• Hot-swap compliant I/O architecture allowing safe insertion into electrically active systems without degrading host reliability or requiring specific power sequencing.
• Includes dedicated routing resources such as DirectConnect and FastConnect to minimize signal propagation delays and ensure deterministic timing.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• PCI-compliant interface designs operating at 66 MHz
• Systems requiring deterministic timing and pin-locking capabilities

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging specifications. Confirm whether the specific part number variant requires lead-free (RoHS) compliance or standard packaging, as these attributes are defined by the final character in the part number string.

Selection Notes

Select this device when a nonvolatile FPGA with high-speed internal routing is required. Ensure the design utilizes the available 1,452 CLBs and 174 I/Os efficiently. Verify that the application environment falls within the specified commercial temperature range if no industrial suffix is present, and confirm power supply stability requirements for the 2.25V to 5.25V operating window.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which were originally developed by Actel Corporation before being acquired by Microsemi and subsequently Microchip Technology. The SX-A series is characterized by its antifuse-based nonvolatile architecture, offering high speed and security compared to volatile SRAM-based FPGAs.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific legacy component are not available in the provided documentation. Consider reviewing the broader SX-A family catalog for devices with similar gate counts and pin configurations, ensuring compatibility with existing PCB footprints and electrical characteristics.
