A54SX32A-1FG144

Overview

The A54SX32A-1FG144 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 supports up to 249 user-programmable I/O pins. The device features 2,880 logic modules, including 1,800 combinatorial cells and 1,080 dedicated flip-flops. It operates with a maximum clock frequency of 250 MHz at the system level and 350 MHz internally. The component utilizes a 144-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm lead pitch. It supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V, ensuring compatibility with various interface requirements.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability or requiring specific power sequencing.
• Deterministic timing performance enabled by patented DirectConnect and FastConnect routing resources that minimize signal propagation delays.
• Integrated Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 (JTAG) for superior diagnostic and verification capabilities.

Applications

• High-performance digital logic integration replacing complex programmable logic devices (CPLDs)
• Fast counters and state machine implementations requiring predictable timing
• Data path logic processing with low capacitance interconnect requirements

Procurement Notes

Verify the ordering suffix 'I' indicates Industrial temperature range (-40°C to +85°C). Confirm the 'G' suffix if RoHS compliance is required. Ensure the FBGA144 package dimensions match the PCB footprint design. Check for current manufacturing status as speed grade -3 is discontinued in this family.

Selection Notes

Select this model for designs requiring 48,000 system gates with deterministic performance. The -1 speed grade offers approximately 15% faster performance than the standard grade. Ensure the application benefits from nonvolatile storage to eliminate configuration boot times. Verify I/O voltage levels match the supported 2.5 V, 3.3 V, and 5 V standards.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, high-performance applications. The family includes variants with capacities ranging from 12,000 to 108,000 system gates. The A54SX32A specifically targets mid-range complexity designs needing robust I/O flexibility and secure, nonvolatile programming.

Replacement Considerations

Direct substitutes within the same package and pinout include other speed grades of the A54SX32A series, such as the standard speed variant or the -2 speed grade for higher performance. Cross-family replacements require careful review of gate counts and I/O configurations.
