A54SX16P-2TQG144

Overview

The A54SX16P-2TQG144 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 1452 logic modules and approximately 24,000 system gates. The device supports up to 350 MHz internal performance with a maximum system frequency of 250 MHz. It features 113 user-programmable I/O pins and up to 990 dedicated flip-flops within a 144-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V I/O standards with hot-swap compliant capabilities.
• Features deterministic timing through patented DirectConnect and FastConnect routing resources that minimize signal propagation delays.
• Includes IEEE 1149.1 (JTAG) boundary-scan testing compliance and FuseLock security technology to prevent reverse engineering.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring nonvolatile configuration without external memory
• Hot-swappable applications involving mixed voltage domains

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, speed grade, and temperature range. Ensure compatibility with existing design tools and programming hardware before procurement.

Selection Notes

Select this component for designs needing high-speed logic with nonvolatile storage. Consider the 144-pin TQFP package constraints and verify that the 113 available I/Os meet interface requirements. Check if the standard speed grade suffices or if faster variants are needed.

Part Context

This part belongs to the Actel SX-A FPGA family, which utilizes antifuse technology for nonvolatile configuration. The SX-A series is designed for cost-effective, high-performance applications, offering a balance of logic density and speed suitable for replacing complex CPLDs or gate arrays.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX16A series, such as A54SX16A-1TQG144 or A54SX16A-TQG144. Verify electrical characteristics and timing parameters when substituting speed grades.

FAQ

What is the maximum internal clock frequency supported by the A54SX16P-2TQG144?

The device supports an internal clock frequency of up to 350 MHz.

How does the SX-A architecture ensure secure configuration?

It uses metal-to-metal antifuses which make reverse engineering difficult, combined with FuseLock technology that prevents unauthorized reading or overwriting of the design.

Can the I/Os be powered up in any order?

Yes, the VCCA and VCCI supplies do not need to be stable during power-up/down and can be powered in any order due to the hot-swap compliant I/O design.
