A54SX16A-1TQ144M

Overview

The A54SX16A-1TQ144M is a military-grade Field Programmable Gate Array from the Actel SX-A family, housed in a 144-pin Thin Quad Flat Pack (TQFP) package. It provides 24,000 system gates and 1,452 logic modules with 113 user-programmable I/Os. The device operates at a maximum system frequency of 250 MHz and an internal clock speed of 350 MHz. It supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance. The component functions within a temperature range of -55°C to +125°C and utilizes nonvolatile antifuse technology.

Feature Summary

• Military-grade reliability with extended temperature coverage for harsh environments
• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Deterministic timing through metal-to-metal programmable interconnect elements

Applications

• Harsh environment aerospace and defense signal processing
• Secure communication systems requiring anti-tamper protection
• Industrial control systems demanding high reliability and deterministic performance
• Spacecraft avionics and satellite payload management

Procurement Notes

Verify the specific ordering suffix 'M' confirms the military temperature grade (-55°C to +125°C). Confirm the '1' speed grade designation matches the required 250 MHz system performance. Ensure the TQFP-144 package type aligns with PCB footprint requirements. Check for RoHS compliance status if applicable to the specific manufacturing lot.

Selection Notes

Select this part when military environmental specifications are mandatory. The 24,000 gate capacity suits moderate complexity logic designs. Verify that the 113 available I/O pins meet interface requirements. Consider the 250 MHz speed grade against design timing constraints. Evaluate the need for nonvolatile configuration to eliminate external boot devices.

Part Context

This component belongs to the Actel SX-A FPGA family, which utilizes 0.22/0.25 micron CMOS antifuse technology. The SX-A series is known for high-performance logic density and secure, nonvolatile programming. The A54SX16A variant represents the mid-range capacity within this family, offering a balance of logic resources and pin count for versatile applications.

Replacement Considerations

Publicly confirmed direct substitutes include other speed grades or packages within the A54SX16A series, such as A54SX16A-TQ144C for commercial use or A54SX16A-FGG144 for FBGA packaging. Cross-family replacements require architectural re-evaluation due to differences in logic cell structure and routing resources.
