A54SX32A-FGG256M

Overview

The A54SX32A-FGG256M is a military-grade Field Programmable Gate Array from the Microchip Actel SX-A family. It provides 48,000 system gates and supports up to 203 user I/Os within a 256-pin Fine Pitch Ball Grid Array package. The device operates on a 0.22 μm / 0.25 μm CMOS antifuse process with a standard supply voltage of 2.5 V. It features three global clock networks and supports mixed-voltage I/O standards including 3.3 V PCI and 5 V TTL. The component is rated for an operating temperature range of -55°C to +125°C.

Feature Summary

• Supports hot-swap operations and power-up/down without supply sequencing requirements
• Provides deterministic timing through metal-to-metal programmable antifuse interconnects
• Includes IEEE 1149.1 compliant boundary-scan testing capabilities
• Features FuseLock technology to prevent reverse engineering and unauthorized access

Applications

• Military avionics systems requiring extended temperature operation
• High-performance digital signal processing logic
• Secure embedded control applications

Procurement Notes

Verify the specific ordering suffix 'M' against official documentation to confirm military grade classification and RoHS compliance status. Confirm current availability as this series may be subject to discontinuation notices or limited production runs. Ensure design files match the exact pinout for the 256-pin FBGA package.

Selection Notes

Select this part for designs requiring high-density logic in a compact footprint with strict environmental constraints. Verify that the 203 I/O count meets interface requirements. Consider the 2.5 V core voltage when designing power delivery networks and level shifting for mixed-voltage peripherals.

Part Context

This component belongs to the Actel SX-A FPGA family, which utilizes nonvolatile antifuse technology. Unlike volatile FPGAs, it does not require external configuration memory. The family offers various speed grades and package options, with the A54SX32A representing the mid-range capacity tier featuring 48,000 system gates.

Replacement Considerations

Check for updated revisions within the A54SX32A series. Consult Microchip for cross-reference data regarding newer FPGA families if lead times are critical.
