A54SX32-TQG144I

Overview

The Microchip Technology A54SX32-TQG144I is an SX-A series Field Programmable Gate Array (FPGA) featuring 48,000 system gates and 2880 configurable logic blocks. It operates within a voltage range of 2.25 V to 5.25 V and supports mixed-voltage I/O standards including 3.3 V, 5 V, and 2.5 V LVCMOS. The device provides up to 113 user-programmable I/O pins and includes three global clock networks. Designed for industrial applications, it functions reliably between -40°C and +85°C. Manufactured using 0.22 μm / 0.25 μm CMOS antifuse technology, the component utilizes a TQFP-144 package.

Feature Summary

• Supports hot-swap operations with no sequencing required for supply voltages
• Enables deterministic timing through metal-to-metal programmable antifuse interconnects
• Provides IEEE 1149.1 compliant boundary-scan testing capabilities
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering

Applications

• Industrial control systems requiring mixed-voltage interfaces
• High-performance logic integration replacing complex CPLDs
• Secure embedded designs utilizing nonvolatile single-chip architecture

Procurement Notes

Verify the specific ordering suffix 'TQG144I' against current manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status as manufacturing changes may affect environmental declarations. Check for active production status or end-of-life notifications prior to procurement planning.

Selection Notes

Select this component when 48,000 system gates and 113 I/Os are required in a 144-pin thin quad flat pack. Ensure the design accommodates the 2.25 V to 5.25 V operating voltage range. Verify that the industrial temperature rating meets environmental requirements. Consider the antifuse technology implications for permanent configuration needs.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilize antifuse technology for nonvolatile configuration. The SX-A series is designed for high-performance applications requiring deterministic timing and robust security features. The A54SX32 variant offers a balance of logic density and I/O count suitable for mid-range programmable logic applications.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade should be verified via official substitution lists. Cross-family migration requires re-evaluation of timing constraints and I/O configurations due to architectural differences.
