A54SX16P-1TQ144I

Overview

The A54SX16P-1TQ144I is a Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and contains 1,452 logic modules (CLBs). The device supports up to 350 MHz internal performance and operates within an industrial temperature range of -40°C to +85°C. It utilizes a TQFP-144 package with 113 user-programmable I/Os.

Feature Summary

• Supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/O standards with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated routing resources such as DirectConnect and FastConnect for deterministic timing and high-speed interconnect.

Applications

• High-performance digital logic integration requiring nonvolatile configuration.
• Systems requiring hot-swappable interface capabilities.
• Industrial applications necessitating extended temperature range operation.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with design tools supporting the SX-A architecture. Confirm RoHS compliance status if required by procurement specifications.

Selection Notes

Select this model for designs requiring approximately 24,000 system gates in a 144-pin thin quad flat pack. Consider the -1 speed grade for improved timing margins over standard devices. Verify that the antifuse programming infrastructure matches the target production environment.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilize metal-to-metal programmable antifuse technology. The family offers single-chip solutions with high performance and low power consumption, distinguishing itself through nonvolatile configuration and robust security features like FuseLock.

Replacement Considerations

Direct replacements include other speed grades within the A54SX16A series, such as the Standard or -2 variants, provided timing constraints allow. Cross-family migration requires architectural re-evaluation due to differences in logic block organization and routing resources.
