A54SX32A-1FG256M

Overview

The A54SX32A-1FG256M is a Field Programmable Gate Array from the Microchip SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and supports up to 203 user-programmable I/O pins within a 256-pin Fine Pitch Ball Grid Array (FBGA) package. The device delivers 250 MHz system performance with a 350 MHz internal clock capability. It operates at supply voltages of 2.5 V, 3.3 V, or 5.0 V, featuring mixed-voltage operation with 5.0 V input tolerance. The -1 speed grade indicates approximately 15% faster performance than the standard speed variant.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability.
• Deterministic timing architecture with DirectConnect and FastConnect routing resources for predictable signal propagation.
• Integrated Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 (JTAG) for superior diagnostic capabilities.

Applications

• High-performance logic integration replacing multiple CPLDs
• PCI-compliant interface designs supporting 66 MHz operations
• Systems requiring deterministic timing and pin-locking

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm that the 'M' suffix aligns with the required military or automotive specifications if applicable. Ensure design files are compatible with the Actel Designer software version supporting the SX-A family.

Selection Notes

Select this component when 48,000 system gates and 203 I/Os are required in a compact FBGA form factor. The -1 speed grade offers improved performance over the standard variant. Verify voltage requirements match the 2.5 V, 3.3 V, or 5.0 V operational range and ensure thermal management suits the FBGA package constraints.

Part Context

This part belongs to the SX-A family of FPGAs, which utilizes antifuse technology for nonvolatile configuration. The family includes devices ranging from 12,000 to 108,000 system gates. The A54SX32A specifically targets applications needing moderate logic density with high-speed performance and robust I/O flexibility.
