A54SX32A-2FGG256

Overview

The A54SX32A-2FGG256 is an antifuse-based Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It provides 48,000 system gates and supports up to 249 user I/Os within a 256-pin Fine Pitch Ball Grid Array (FBGA) package. The device operates at a standard supply voltage of 2.5 V with a range of 2.25 V to 2.75 V. It features a maximum operating frequency of 238 MHz and includes 2,880 logic modules with dedicated flip-flops. The component is rated for industrial temperature applications, functioning reliably between -40°C and +85°C.

Feature Summary

• Utilizes nonvolatile antifuse technology for permanent configuration without external memory.
• Supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems.
• Includes IEEE 1149.1 Boundary-Scan Testing capabilities for diagnostic verification.

Applications

• Industrial control systems requiring deterministic timing and high reliability.
• Automotive electronics operating under extended temperature conditions.
• High-speed data path logic and state machine implementations.
• Secure embedded designs utilizing antifuse resistance to reverse engineering.

Procurement Notes

Verify the specific suffix '2' indicates the speed grade corresponding to approximately 25% faster performance than the standard variant. Confirm the 'G' suffix denotes RoHS-compliant packaging if environmental compliance is required. Ensure the 'I' suffix matches the intended industrial temperature range specifications for your application environment.

Selection Notes

Select this model when 48,000 system gates are sufficient for the design complexity. The 256-pin FBGA package requires appropriate PCB footprint design for fine-pitch soldering. Consider the 238 MHz maximum frequency against system timing requirements. Verify that the 2.5 V core voltage aligns with available power rails in the target hardware architecture.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their metal-to-metal antifuse interconnect technology. The family offers various gate counts and package options, with the A54SX32A representing the mid-range capacity tier. The SX-A series is designed for applications demanding low power consumption and high performance in a single-chip solution.

Replacement Considerations

Compatible alternatives within the same family include the A54SX32A-FGG256 or A54SX32A-2FG256I, depending on required speed grades and temperature ratings. Cross-family migration to newer Microchip FPGA architectures may require significant design re-verification due to architectural differences.
