A54SX16A-TQG144

Overview

The A54SX16A-TQG144 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 frequency of 227 MHz with a supply voltage range of 2.25 V to 2.75 V (nominal 2.5 V). The device provides 113 user-programmable I/Os and utilizes a TQFP-144 package. Designed for commercial applications, it supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Configurable I/O standards supporting mixed-voltage operation including 3.3V, 5V, and 2.5V levels
• Integrated boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG)

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• Systems requiring deterministic timing and pin-locking capabilities
• Applications necessitating secure design protection against reverse engineering

Procurement Notes

Verify the specific speed grade suffix in the part number to confirm performance characteristics. Confirm that the ordering suffix matches the required temperature range and packaging specifications. Ensure compatibility with Actel Designer software versions for programming and verification.

Selection Notes

Select this component when 24,000 system gates and 144 pins are required within a thin quad flat pack. Consider the commercial temperature grade limits for environmental suitability. Evaluate the 227 MHz speed grade against system timing requirements before finalizing the design.

Part Context

This model belongs to the Microchip (formerly Actel) SX-A family of FPGAs. It shares architectural features such as antifuse technology and cluster-based logic modules with other devices in the series, differing primarily in gate count, I/O availability, and package options.

Replacement Considerations

Direct replacements include other speed grades within the A54SX16A series, such as A54SX16A-1TQG144 or A54SX16A-2TQG144, provided the package and temperature ratings remain compatible.
