A54SX32A-FG256M

Overview

The A54SX32A-FG256M is a nonvolatile Field Programmable Gate Array from the Microchip SX-A family, utilizing antifuse technology. It provides 48,000 system gates and supports up to 203 user-programmable I/Os within a 256-pin Fine Pitch Ball Grid Array (FBGA) package. The device operates at a standard speed grade with a maximum system performance of 250 MHz and internal clock frequencies reaching 350 MHz. It features three global clock networks and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V levels with 5 V input tolerance.

Feature Summary

• Antifuse-based architecture providing permanent low-impedance connections and high security against reverse engineering
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Deterministic timing through dedicated routing resources like DirectConnect and FastConnect for predictable signal propagation
• Integrated Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 for in-system diagnostics

Applications

• High-performance logic integration replacing complex programmable logic devices (CPLDs)
• Systems requiring deterministic timing and fast counters or state machines
• Applications necessitating secure programming and protection of intellectual property via FuseLock technology

Procurement Notes

Verify the specific suffix 'M' indicates the Military temperature grade (-55°C to +125°C) as per the ordering information matrix. Confirm that the FG256 package corresponds to the 1.0 mm Fine Pitch Ball Grid Array variant. Ensure compatibility with Actel Designer software versions supporting the SX-A family for place-and-route implementation.

Selection Notes

Select this component when 48,000 system gates are required alongside a 256-pin surface-mount footprint. The military temperature grade is suitable for harsh environments. Consider the 250 MHz system performance limit for timing closure. Verify that the 203 available I/O pins meet the interface requirements for the target application design.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse process technology. The family includes devices ranging from 12,000 to 108,000 system gates. The A54SX32A specifically offers a balance of logic density and I/O count, positioned between the A54SX16A and A54SX72A in terms of capacity.
