A54SX08A-FGG144

Overview

The A54SX08A-FGG144 is a nonvolatile Field Programmable Gate Array from the Microsemi SX-A family, utilizing metal-to-metal antifuse technology. It provides 12,000 typical system gates and 768 logic modules (CLBs). The device supports up to 130 user-programmable I/O pins and features three global clock networks. It operates with supply voltages of 2.5 V, 3.3 V, or 5 V, supporting mixed-voltage operation with 5 V input tolerance. The -F speed grade indicates performance approximately 40% slower than the standard grade. It is housed in a 144-pin Fine Pitch Ball Grid Array package.

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 voltage sequencing requirements.
• 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 requiring 66 MHz PCI compliance
• Applications needing mixed-voltage I/O support for 3.3 V/5 V PCI, 5 V TTL, and 3.3 V LVTTL

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm temperature grade and packaging compliance. Ensure the selected speed grade matches the required system timing constraints. Confirm that the fine pitch ball grid array package dimensions align with the printed circuit board footprint specifications.

Selection Notes

Select this component when a nonvolatile FPGA architecture is preferred over volatile alternatives to eliminate configuration memory requirements. Consider the -F speed grade only if lower performance thresholds are acceptable relative to the standard grade. Verify that the available system gate count and I/O pin density meet the specific logic capacity needs of the target application.

Part Context
