A54SX16P-1TQG144M

Overview

The A54SX16P-1TQG144M is a Field Programmable Gate Array from the SX-A family, featuring 24,000 system gates and 1,452 logic modules. It operates at a maximum clock frequency of 250 MHz with an internal performance of 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It is housed in a 144-pin Thin Quad Flat Pack (TQFP) package with a height of 1.40 mm. The military temperature grade (-55°C to +125°C) is indicated by the 'M' suffix.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down without sequencing requirements for supply voltages.
• Includes dedicated routing resources such as DirectConnect and FastConnect for deterministic timing and high-speed signal propagation.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring nonvolatile configuration without external memory
• Military applications necessitating extended temperature range operation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature rating. Ensure compatibility with existing PCB footprints for the TQFP-144 package. Confirm that the military grade specification meets project environmental requirements.

Selection Notes

Select this component for designs requiring 24,000 system gates with high-speed internal clocking capabilities. Consider the SX-A architecture for its ability to achieve 100% resource utilization and pin locking. Evaluate the mixed-voltage I/O support if interfacing with multiple voltage domains is necessary.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated on a high-voltage twin-well CMOS process. The family offers various gate densities ranging from 8,000 to 108,000 system gates. The SX-A series is known for its sea-of-modules architecture and patented antifuse technology.

Replacement Considerations

Check for discontinued status or end-of-life notifications. Verify if newer Microchip FPGA families offer equivalent gate counts and performance metrics. Ensure any substitute maintains the required TQFP-144 footprint and military temperature specifications.
