A54SX08A-1FGG144

Overview

The A54SX08A-1FGG144 is an antifuse-based Field Programmable Gate Array from the Microsemi SX-A family. It provides 12,000 system gates and 768 logic modules (CLBs). The device operates within a voltage range of 2.25V to 5.25V and supports up to 111 user-programmable I/O pins in its 144-pin Fine Pitch Ball Grid Array package. It features a maximum system performance of 250 MHz with internal clock frequencies reaching 350 MHz. The component includes three global clocks and complies with IEEE Standard 1149.1 for boundary-scan testing.

Feature Summary

• Utilizes metal-to-metal programmable antifuse technology for permanent, nonvolatile configuration without external memory requirements.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing constraints.
• Includes Silicon Explorer II for unique in-system diagnostic verification and debugging capabilities.

Applications

• Integration of complex CPLD functionality into single-chip solutions
• High-performance data path logic and fast counters
• PCI-compliant interface designs requiring deterministic timing

Procurement Notes

Verify the specific ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) as defined in the official datasheet matrix. Confirm that the 'G' suffix indicates RoHS compliant packaging if required by environmental specifications. Ensure compatibility with Actel Designer software versions supporting the SX-A architecture prior to procurement.

Selection Notes

Select this model when 12,000 system gates are sufficient for the design logic density. The -1 speed grade offers approximately 15% faster performance than the standard grade. Verify that the 144-pin FBGA package fits the PCB footprint constraints. Consider the -F speed grade only if lower performance at reduced power is acceptable, or higher grades for increased throughput.

Part Context

This component belongs to the SX-A family of FPGAs manufactured by Microsemi (formerly Actel). The family utilizes 0.22 μm / 0.25 μm CMOS process technology. The A54SX08A variant represents the entry-level capacity within the series, offering 768 CLBs compared to larger variants like the A54SX16A or A54SX32A which provide higher gate counts and I/O options.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific component are not available in the provided documentation. Designers should consult the manufacturer's obsolescence notices or contact sales representatives for potential migration paths within the SX-A family or newer architectures.
