A54SX32A-FG144

Overview

The A54SX32A-FG144 is a Field Programmable Gate Array from the SX-A family, manufactured by Microsemi. It features 48,000 system gates and 2,880 logic modules within a 144-pin Fine Pitch Ball Grid Array (FBGA) package. The device supports up to 111 user-programmable I/O pins and operates with a maximum clock frequency of 250 MHz at the standard speed grade. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements
• Hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing requirements
• Deterministic timing architecture with DirectConnect and FastConnect routing resources
• Integrated Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1

Applications

• 66 MHz PCI compliant systems
• Mixed-voltage interface designs supporting 3.3 V, 5 V PCI, and 5 V TTL
• High-performance state machines and fast counters requiring deterministic timing
• Secure applications utilizing FuseLock technology to prevent reverse engineering

Procurement Notes

Verify the specific speed grade suffix associated with the FG144 package, as performance varies between standard, -1, and -2 grades. Confirm the temperature range designation matches the application environment. Check for RoHS compliance status if required by procurement specifications. Ensure the ordering suffix accurately reflects the desired packaging and environmental rating.

Selection Notes

Select this component when 48,000 system gates are required in a compact 144-pin FBGA footprint. Consider the standard speed grade for general-purpose logic or faster grades for higher frequency requirements. Evaluate the mixed-voltage I/O capabilities if interfacing with 5 V legacy devices. Verify that the antifuse nonvolatility meets the design's configuration retention needs.

Part Context

This part belongs to the Actel SX-A FPGA family, which offers high-density logic in small packages. The SX-A series is characterized by its patented antifuse technology and deterministic performance. The FG144 package provides a fine-pitch ball grid array option suitable for space-constrained PCB layouts while maintaining robust signal integrity.

Replacement Considerations

Direct replacements include other speed grades of the A54SX32A in the same FG144 package, such as A54SX32A-1FG144 or A54SX32A-2FG144. Cross-family upgrades may involve the A54SX72A for increased capacity, though pin compatibility must be verified.
