A54SX16A-2FGG256I

Overview

The A54SX16A-2FGG256I is a Field Programmable Gate Array from the SX-A family, manufactured by Microsemi. It features 24,000 system gates and supports up to 180 user-programmable I/O pins within a 256-pin Fine Pitch Ball Grid Array (FBGA) package. The device operates at a maximum system frequency of 250 MHz with internal performance reaching 350 MHz. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V. The industrial temperature grade (-40°C to +85°C) is indicated by the 'I' suffix.

Feature Summary

• Supports hot-swap compliant I/Os for safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• High-performance digital logic integration requiring low latency.
• Systems requiring nonvolatile single-chip FPGA solutions.
• Industrial applications necessitating wide operating temperature ranges.

Procurement Notes

Verify component authenticity through authorized Microsemi distributors or official channels. Confirm that the specific ordering suffix matches the required speed grade, package type, and temperature range. Check for end-of-life status or discontinuance notifications prior to finalizing procurement plans.

Selection Notes

Select this model when 24,000 system gates and 180 I/Os are sufficient for the design. Ensure the FBGA256 package fits the PCB layout constraints. Verify that the -2 speed grade meets the 250 MHz system performance requirement compared to standard or slower grades.
