A54SX08A-1FG144

Overview

The A54SX08A-1FG144 is a Field Programmable Gate Array from the Microsemi SX-A family, utilizing antifuse technology. It features 768 Configurable Logic Blocks (CLBs) and approximately 12,000 system gates. The device supports a maximum system performance of 250 MHz with an internal clock frequency up to 350 MHz. It operates within a voltage range of 2.25 V to 5.25 V and provides up to 111 user-programmable I/O pins in the 144-pin Fine Pitch Ball Grid Array (FBGA) package. The component includes dedicated flip-flops for sequential logic implementation.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnects that provide permanent low-impedance connections without configuration bitstreams.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength capabilities.
• Hot-swap compliant I/Os allow insertion into active systems without power sequencing requirements or damage to the host.
• Includes deterministic timing architecture with DirectConnect and FastConnect routing resources for predictable signal propagation.

Applications

• Integration of complex CPLD functionality into high-performance single-chip solutions
• Designs requiring deterministic timing and user-controllable delay characteristics
• Systems necessitating secure programming with reverse-engineering protection via FuseLock technology

Procurement Notes

Verify the specific speed grade suffix '1' indicates approximately 15% faster performance than the standard speed variant. Confirm the 'FG' package designation corresponds to the 1.0 mm pitch FBGA form factor. Ensure the temperature grade matches the required operational environment specifications for the target application.

Selection Notes

Select this device when designs require approximately 12,000 system gates with high-speed performance exceeding standard commercial grades. Consider the 144-pin FBGA package for space-constrained applications requiring fine-pitch connectivity. Evaluate the need for hot-swap capabilities and nonvolatile storage if configuration memory is not desired in the system architecture.

Part Context

This component belongs to the Actel/Microsemi SX-A family of FPGAs, which are fabricated on a 0.22 μm / 0.25 μm CMOS process. The family utilizes antifuse technology rather than SRAM-based configuration, offering inherent security and zero standby power consumption. The SX-A series is designed to replace multiple discrete logic components with a single integrated circuit.

Replacement Considerations

Public confirmed substitute part numbers: A54SX08A-FG144 (Standard Speed), A54SX08A-2FG144 (Faster Speed). Verify pinout compatibility and timing requirements when migrating between speed grades within the same package type.
