A54SX16A-1FGG144

Overview

The A54SX16A-1FGG144 is a Field Programmable Gate Array from the SX-A family, manufactured by Microsemi. It features 24,000 system gates and 1,452 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 includes dedicated flip-flops for sequential logic. Operating at a standard supply voltage of 2.5 V with a range of 2.25 V to 2.75 V, it delivers a maximum system performance frequency of 263 MHz and an internal clock speed of 350 MHz. The component is designed for commercial temperature applications ranging from 0°C to +70°C.

Feature Summary

• Utilizes metal-to-metal programmable antifuse technology for nonvolatile configuration and permanent interconnects.
• Supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes deterministic timing architecture with DirectConnect and FastConnect routing resources for predictable signal propagation.

Applications

• High-performance digital logic integration requiring low power consumption.
• Systems requiring hot-swappable interface capabilities.
• Designs needing secure programming with reverse engineering protection via FuseLock technology.
• Applications utilizing 66 MHz PCI compliance or mixed-voltage signaling environments.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure compatibility with Actel Designer software versions supporting the SX-A family. Check for RoHS compliance status if required by assembly specifications. Confirm availability through authorized distributors as lead times may vary.

Selection Notes

Select this model when 24,000 system gates and 144-pin FBGA packaging are required. The -1 speed grade offers approximately 15% faster performance than the standard grade. Ensure the design fits within the 111 available user I/Os and utilizes the 2.5 V core voltage. Verify that the commercial temperature range meets the operational environment requirements.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are built on 0.22 μm / 0.25 μm CMOS antifuse technology. The family provides a single-chip solution integrating high performance with low power consumption. The SX-A architecture is characterized by its sea-of-modules organization and patented antifuse interconnects, distinguishing it from volatile SRAM-based FPGAs.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX16A series, such as the standard speed variant or the -2 speed grade. Cross-family migration to larger devices like the A54SX32A requires careful review of resource utilization and pin mapping constraints.
