A54SX08A-1FGG144I

Overview

The A54SX08A-1FGG144I is a nonvolatile Field Programmable Gate Array from the Microsemi SX-A family, utilizing antifuse technology. It provides 12,000 typical system gates and 768 logic modules (CLBs). The device supports up to 111 user-programmable I/O pins within a 144-pin Fine Pitch Ball Grid Array package. It operates at an industrial temperature range of -40°C to +85°C with a speed grade of -1, offering approximately 15% faster performance than standard speed grades.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down without sequencing requirements for supply voltages.
• Includes deterministic timing capabilities with DirectConnect and FastConnect routing resources for predictable signal propagation.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• Low-power, high-performance designs requiring cost-effective integration
• Systems needing mixed-voltage operation with 3.3 V / 5 V PCI compliance
• Applications requiring deterministic timing and pin-locking capabilities

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure compatibility with existing PCB footprints for the 144-pin FBGA configuration. Confirm RoHS compliance status if required by local regulations.

Selection Notes

Select this component when a nonvolatile FPGA architecture is preferred over volatile SRAM-based devices to eliminate configuration memory. Consider the -1 speed grade for applications requiring higher performance than standard grades while maintaining industrial temperature stability. Evaluate the 111 available I/Os against system interface requirements.
