A54SX16P-1PQ208M

Overview

The A54SX16P-1PQ208M is a nonvolatile Field Programmable Gate Array from the Microsemi SX-A family, utilizing antifuse technology. It provides 24,000 system gates and 1,452 configurable logic blocks (CLBs). The device supports up to 175 user-programmable I/Os within a 208-pin Plastic Quad Flat Pack (PQFP) package. It operates with supply voltages of 2.5 V, 3.3 V, or 5 V, featuring mixed-voltage operation with 5 V input tolerance. The -1 speed grade delivers approximately 15% faster performance than standard grades, supporting internal clock frequencies up to 350 MHz. It includes three global clocks and complies with IEEE 1149.1 boundary-scan testing.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability or requiring specific voltage sequencing.
• Configurable I/O modules supporting multiple standards including 3.3V/5V PCI, 5V TTL, 3.3V LVTTL, and 2.5V LVCMOS2 with individually selectable slew rates.
• Deterministic timing architecture with DirectConnect and FastConnect routing resources enabling fast signal propagation and 100% pin locking.

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the ordering suffix 'M' against official documentation, as it typically denotes Military temperature grade (-55°C to +125°C), which may differ from standard Industrial availability. Confirm RoHS compliance status, as older SX-A variants often contain lead. Ensure design tools support the specific antifuse programming requirements for this part number.

Selection Notes

Select this model for applications requiring deterministic timing and high performance in a PQFP package. The -1 speed grade offers improved timing over standard devices. Consider the A54SX16A series if lower cost is prioritized over speed. Verify that the target application can accommodate the 208-pin footprint and the specific voltage levels supported by the SX-A I/O banks.

Part Context

This component belongs to the Actel/Microsemi SX-A family of FPGAs, designed for low-power, high-performance designs using 0.22 μm / 0.25 μm CMOS antifuse technology. The family ranges from 12,000 to 108,000 system gates, offering a cost-effective alternative to CPLDs and gate arrays while integrating complex logic onto a single chip.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult Microchip Technology for current lifecycle status and potential obsolescence notices regarding the SX-A family.
