A54SX16A-FGG144

Overview

The A54SX16A-FGG144 is a Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 logic modules within a 144-pin Fine Pitch Ball Grid Array (FGG) package. The device supports up to 111 user-programmable I/O pins and features 3 global clock networks. It operates with internal performance up to 350 MHz and system performance up to 250 MHz. The component supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V, ensuring compatibility with various interface standards including PCI and TTL.

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 insertion into active systems without degrading host reliability or requiring specific power sequencing.
• Deterministic timing architecture featuring DirectConnect and FastConnect routing resources to minimize signal propagation delays.
• Integrated security via FuseLock technology and hidden security fuses to prevent reverse engineering and unauthorized design access.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays
• PCI-compliant interfaces supporting 66 MHz bus speeds
• Systems requiring deterministic timing and pin-locking capabilities
• Applications necessitating hot-swappable hardware configurations

Procurement Notes

Verify the manufacturer origin, as the part was originally produced by Actel Corporation before acquisition by Microsemi. Confirm the specific speed grade suffix corresponds to the required timing constraints, noting that standard speed grades are available while higher-speed variants like -3 have been discontinued. Ensure the ordering suffix matches the desired temperature range and packaging compliance requirements.

Selection Notes

Select this model when 24,000 system gates and 1,452 logic modules are sufficient for the design. The FGG144 package is appropriate for applications requiring a 1.0 mm pitch fine-pitch BGA footprint. Consider the 111 available user I/Os against interface requirements. Verify that the 2.5V/3.3V/5V mixed-voltage support aligns with the target system's voltage domains.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their high-density antifuse technology and low-power consumption. The SX-A series offers a scalable range of capacities, with the A54SX16A positioned between the smaller A54SX08A and larger A54SX32A devices in terms of logic resources and I/O count.

Replacement Considerations

Direct functional replacements within the same capacity class include other speed grades of the A54SX16A series, such as A54SX16A-1FGG144 or A54SX16A-2FGG144, provided timing requirements are met. Note that the -3 speed grade has been discontinued. Cross-family migration to newer Microchip FPGA architectures may require significant design re-verification.
