A54SX16P-1PQG208

Overview

The A54SX16P-1PQG208 is an antifuse-based Field Programmable Gate Array (FPGA) from the Actel SX-A family, manufactured by Microchip Technology. It features 24,000 system gates and 1,452 configurable logic blocks (CLBs). The device supports up to 175 user-programmable I/Os and includes 924 dedicated flip-flops. It operates within a voltage range of 2.25 V to 2.75 V and is available in a 208-pin Plastic Quad Flat Pack (PQFP) package. The standard speed grade provides 250 MHz system performance with 350 MHz internal clock capability.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology for permanent interconnection.
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements.
• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V standards with 5 V input tolerance.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing (BST) and Actel FuseLock security features.

Applications

• High-performance digital signal processing requiring deterministic timing.
• Systems requiring hot-swappable capabilities or cold-sparing redundancy.
• Secure applications needing protection against reverse engineering via antifuse architecture.
• PCI-compliant interfaces operating at 66 MHz.

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm the specific speed grade suffix corresponds to required timing constraints. Check for RoHS compliance status if environmental regulations apply. Ensure the PQFP-208 package matches PCB footprint specifications. Review datasheet revisions for any updates regarding electrical characteristics or pin assignments.

Selection Notes

Select this model when nonvolatile configuration is preferred over SRAM-based FPGAs to eliminate external configuration memory. Consider the SX-A family for designs requiring high-speed local routing via DirectConnect and FastConnect resources. Evaluate thermal dissipation requirements for the PQFP-208 package under maximum load conditions. Verify that the 24,000 gate capacity meets logic density needs without excessive resource utilization.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which were originally developed by Actel Corporation before its acquisition by Microsemi and subsequently Microchip Technology. The SX-A series is characterized by its antifuse technology, offering high reliability and security compared to volatile FPGA alternatives. It serves as a bridge between complex CPLDs and larger gate arrays in terms of performance and integration capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Microchip Technology for current equivalent products or migration paths from discontinued antifuse devices.
