A54SX32A-2FGG256I

Overview

The A54SX32A-2FGG256I is an antifuse-based FPGA from the SX-A family, manufactured by Microchip Technology. It provides 48,000 system gates and supports up to 203 user I/Os within a 256-pin Fine Pitch Ball Grid Array (FBGA) package. The device operates at a supply voltage of 2.5 V with a range of 2.25 V to 2.75 V. It features a maximum operating frequency of 250 MHz for system performance and 350 MHz internally. The component is rated for industrial temperature applications, functioning between -40°C and +85°C.

Feature Summary

• Supports hot-swap capabilities and mixed-voltage operation across 2.5 V, 3.3 V, and 5 V levels with 5 V input tolerance.
• Includes nonvolatile antifuse technology ensuring deterministic timing and protection against reverse engineering via FuseLock.
• Integrates boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• High-performance logic integration requiring low power consumption
• Systems necessitating hot-swappable interface connections
• Industrial control environments requiring extended temperature stability

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the 'G' suffix indicates RoHS-compliant packaging if required. Ensure the '2' speed grade matches the target system clock requirements. Validate that the FBGA-256 package dimensions align with the PCB footprint design.

Selection Notes

Select this model when 48,000 system gates are sufficient for the design complexity. The -2 speed grade offers approximately 25% faster performance than standard grades. Consider the 256-pin FBGA package for high-density interconnect needs. Verify compatibility with Actel Designer software for place-and-route implementation.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series is designed for cost-effective, single-chip solutions that replace multiple complex programmable logic devices. The A54SX32A variant specifically targets designs needing moderate logic capacity with high-speed performance characteristics.
