A54SX32A-TQG144

Overview

The A54SX32A-TQG144 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It provides 48,000 system gates and features 113 user-programmable I/O pins within a 144-pin Thin Quad Flat Pack (TQFP) package. The device operates on a 0.22 μm / 0.25 μm CMOS antifuse process technology. Key electrical specifications include a standard operating voltage of 2.5 V, with support for mixed-voltage I/O standards including 3.3 V and 5 V. The architecture supports up to 1,080 dedicated flip-flops and includes three global clock networks.

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 sequencing requirements for supply voltages.
• Includes configurable weak-resistor pull-up or pull-down capabilities for I/O pins during power-up to ensure deterministic states.
• Features individual output slew rate control and boundary-scan testing compliance with IEEE Standard 1149.1.

Applications

• High-performance logic integration requiring deterministic timing and fast signal propagation.
• Systems requiring nonvolatile configuration without external configuration bitstreams.
• Applications involving mixed-voltage interfaces supporting 3.3 V, 5 V PCI, and 5 V TTL standards.

Procurement Notes

Verify the specific speed grade suffix associated with the TQG144 package variant, as performance characteristics vary between standard and faster grades. Confirm that the ordering suffix indicates the correct temperature range for the intended operational environment. Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture. Check for any specific packaging options such as RoHS compliance if required by project specifications.

Selection Notes

Select this component when 48,000 system gates and 113 I/Os are sufficient for the design complexity. Consider the TQFP-144 package constraints regarding pin count and thermal dissipation. Evaluate the need for specific speed grades if higher internal clock frequencies than the standard grade are required. Verify that the antifuse technology aligns with the requirement for nonvolatile, secure programming without reverse engineering risks.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. The family ranges from 8,000 to 108,000 system gates, offering various package options including TQFP, FBGA, and PBGA. The SX-A series is characterized by its sea-of-modules architecture, providing high performance and low power consumption for complex logic applications.

Replacement Considerations

Direct replacements within the same package and pinout may include other speed grades of the A54SX32A series, such as A54SX32A-1TQG144 or A54SX32A-2TQG144, provided the timing requirements are met. Cross-family replacements require careful verification of gate counts, I/O configurations, and architectural differences.
