A54SX32A-TQG144I

Overview

The A54SX32A-TQG144I is a Field Programmable Gate Array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and features 2,880 logic modules with 1,800 combinatorial cells and 1,080 dedicated flip-flops. The device supports up to 249 user-programmable I/O pins and includes three global clock networks. It operates within an industrial temperature range of -40°C to +85°C and utilizes 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 hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements.
• Enables 100% resource utilization and 100% pin locking through deterministic, user-controllable timing architecture.
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring nonvolatile configuration without external bitstream memory
• Hot-swap capable electronic designs

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, speed grade, and temperature rating. Confirm RoHS compliance status as packaging options vary. Ensure design compatibility with the SX-A family specifications before procurement.

Selection Notes

Select this component for applications requiring 48,000 system gates with industrial temperature stability. Verify that the 144-pin TQFP package meets PCB layout constraints. Ensure the design leverages the antifuse architecture benefits for security and nonvolatile operation.

Part Context

This part belongs to the Actel SX-A FPGA family, which uses antifuse technology for high-speed, secure, and nonvolatile logic implementation. The SX-A series offers varying gate counts and package options to support diverse embedded logic requirements across commercial and industrial sectors.

Replacement Considerations
