A54SX16A-PQG208M

Overview

The A54SX16A-PQG208M is a nonvolatile FPGA from the Microchip SX-A family, utilizing antifuse technology. It provides 24,000 system gates and supports up to 175 user I/Os in its 208-pin PQFP package. The device operates on a 2.5 V core voltage with mixed-voltage I/O support for 3.3 V and 5 V standards. It features three global clock networks and dedicated flip-flops for high-performance logic implementation.

Feature Summary

• Nonvolatile antifuse architecture eliminates configuration bitstreams and prevents reverse engineering via FuseLock technology.
• Hot-swap compliant I/Os allow insertion into active systems without power sequencing requirements or system degradation.
• Deterministic timing achieved through metal-to-metal interconnects and specialized routing resources like DirectConnect and FastConnect.

Applications

• High-speed data path logic and fast counters requiring deterministic propagation delays.
• Systems requiring hot-swappable interface capabilities without complex power-up sequencing.
• Secure designs needing protection against reverse engineering and unauthorized access.

Procurement Notes

Verify the specific speed grade suffix associated with the PQG208M designation, as standard ordering information lists PQ208 packages. Confirm current availability status directly with Microchip Technology distributors, as this component may be subject to discontinuation notices or limited supply conditions typical of legacy antifuse devices.

Selection Notes

Select this device when a nonvolatile solution with high performance and security is required. Ensure the design utilizes the available 24,000 system gates efficiently. Verify that the 2.5 V core voltage and mixed-voltage I/O capabilities align with the target system's power rails and signal levels.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. The family offers a range of capacities from 12,000 to 108,000 system gates, providing a versatile platform for integrating CPLD and gate array functionalities into single-chip solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider evaluating other SX-A family members such as the A54SX16A-FG256M or A54SX32A series if pin count or capacity adjustments are permissible within the design constraints.
