A54SX32A-1TQG144

Overview

The A54SX32A-1TQG144 is a nonvolatile Field Programmable Gate Array from the SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 typical system gates and 2,880 logic modules within a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 113 user-programmable I/O pins and includes dedicated flip-flops for sequential logic implementation. Operating at speed grade -1, it delivers approximately 15% faster performance than standard speed grades. The component operates within a commercial temperature range of 0°C to +70°C and utilizes a single 2.5V core supply voltage.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements
• Features deterministic timing through metal-to-metal programmable antifuse interconnect elements
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG)
• Provides configurable weak-resistor pull-up or pull-down options for I/O pins during power-up

Applications

• High-performance digital signal processing requiring deterministic latency
• Industrial control systems utilizing mixed-voltage I/O standards
• Secure embedded applications protected by FuseLock anti-tamper technology
• PCI-compliant interface designs operating at 66 MHz

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, speed grade, and temperature rating. Ensure compliance with RoHS directives if lead-free packaging is required. Confirm availability status as manufacturing lifecycles may change. Validate that the selected variant matches the intended thermal and electrical specifications for the target application environment.

Selection Notes

Select this device when 48,000 system gates and 113 I/Os are sufficient for the design complexity. The -1 speed grade offers improved performance over standard variants while maintaining compatibility with the TQFP-144 footprint. Consider the commercial temperature range limits when evaluating environmental constraints. Verify that the antifuse architecture aligns with the need for permanent, nonvolatile configuration without external memory.

Part Context

This component belongs to the Actel SX-A FPGA family, which utilizes antifuse technology for permanent programming. The SX-A series is designed for low-power, high-density applications requiring robust security features. The A54SX32A variant sits between the smaller A54SX16A and larger A54SX72A devices in terms of logic capacity and I/O count within the same architectural framework.

Replacement Considerations

Direct pin-compatible replacements within the SX-A family include other A54SX32A variants with different speed grades or packages, such as A54SX32A-2TQG144 for higher performance or A54SX32A-TQG144 for standard speed. Cross-family migration to newer Microchip FPGA architectures requires schematic and software redesign due to architectural differences.
