A54SX16P-1PQG208M

Overview

The A54SX16P-1PQG208M is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and supports up to 175 user-programmable I/O pins in a 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates at a standard speed grade with internal clock frequencies reaching 350 MHz. It features three global clock networks and supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 I/Os.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability.
• Configurable weak-resistor pull-up or pull-down capabilities for I/O pins during power-up to ensure deterministic states.
• Supports Boundary-Scan Testing compliant with IEEE Standard 1149.1 via dedicated or flexible JTAG modes.

Applications

• High-performance logic integration requiring deterministic timing and fast signal propagation.
• Systems requiring hot-swappable interface capabilities without complex voltage sequencing.
• Applications needing secure design protection against reverse engineering using FuseLock technology.

Procurement Notes

Verify component authenticity through authorized Microchip Technology channels. Confirm that the specific ordering suffix matches the required temperature grade and package type. Ensure compliance with relevant environmental directives such as RoHS if applicable to the manufacturing batch. Check for any product change notices regarding availability or specifications before finalizing procurement.

Selection Notes

Select this model when 24,000 system gates and 175 I/Os are sufficient for the design requirements. The PQFP-208 package is suitable for surface-mount applications requiring robust mechanical stability. Consider the standard speed grade performance characteristics relative to the target system clock frequencies. Verify that the 2.5 V, 3.3 V, and 5 V mixed-voltage I/O support aligns with the peripheral interface standards.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, high-performance designs. The family utilizes antifuse technology to provide nonvolatile configuration, eliminating the need for external configuration memory. The SX-A architecture emphasizes optimal register/logic mix and fast routing resources like DirectConnect and FastConnect.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX16A series, such as A54SX16P-2PQG208M for faster performance. Devices with different gate counts like A54SX08A or A54SX32A may require schematic modifications due to resource differences. Cross-family migration to newer Microchip FPGA architectures requires comprehensive design re-verification.
