A54SX32A-1FG256

Overview

The A54SX32A-1FG256 is a Field Programmable Gate Array from the Microchip Technology SX-A family, utilizing 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 operates at a maximum frequency of 278 MHz with a standard supply voltage range of 2.25 V to 2.75 V. It features three global clock networks and includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1.

Feature Summary

• Supports hot-swappable I/O configurations for safe insertion into active systems without power sequencing requirements.
• Integrates dedicated routing resources including DirectConnect and FastConnect for deterministic signal propagation times.
• Includes Actel Secure Programming Technology with FuseLock to prevent unauthorized design access or reverse engineering.

Applications

• High-speed data path logic and fast counters requiring low latency interconnects
• Complex state machine implementations with strict timing constraints
• PCI-compliant interface designs operating at 66 MHz

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm that the specific ordering suffix matches the required speed grade and temperature rating. Ensure proper handling procedures are followed due to moisture sensitivity classification. Review current product lifecycle status as availability may be limited.

Selection Notes

Select this model when 48,000 system gates and 203 I/Os are required in a compact FBGA form factor. The -1 speed grade offers approximately 15% faster performance than the standard variant. Verify thermal management requirements for the specific application environment before finalizing the selection.

Part Context

This component belongs to the SX-A family of nonvolatile FPGAs fabricated on 0.22 μm / 0.25 μm CMOS process technology. The family ranges from 12,000 to 108,000 system gates, offering mixed-voltage I/O support for 2.5 V, 3.3 V, and 5 V standards.

Replacement Considerations

Compatible alternatives within the same series include A54SX32A-FG256 and A54SX32A-FGG256A. These variants share identical logical resources but differ in package type or speed grade specifications.
