A54SX32-1BGG329

Overview

The A54SX32-1BGG329 is a Field Programmable Gate Array from the Actel SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum system frequency of 250 MHz with an internal performance of 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It is housed in a 329-pin Plastic Ball Grid Array (PBGA) package and is rated for industrial temperature operation ranging from -40°C to +85°C.

Feature Summary

• Supports hot-swap compliant I/Os allowing power-up/down without supply voltage sequencing requirements
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking
• Includes unique in-system diagnostic and verification capability via Silicon Explorer II
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering

Applications

• 66 MHz PCI compliant designs
• Low-power, high-performance single-chip solutions
• Systems requiring mixed-voltage operation with 5 V input tolerance

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct channels. Confirm that the specific ordering suffix corresponds to the required speed grade, package type, and industrial temperature range specifications before finalizing acquisition.

Selection Notes

Select this model when 48,000 system gates and 249 user I/Os are required within a 329-pin BGA footprint. Ensure design compatibility with the SX-A architecture's antifuse programming methodology and verify that the 250 MHz system performance meets the target application timing constraints.

Part Context

This component belongs to the Actel SX-A FPGA family, which offers nonvolatile, single-chip solutions fabricated on CMOS antifuse technology. The SX-A series integrates CPLD and FPGA capabilities, providing high-density logic resources with low power consumption and robust security features against unauthorized access.

Replacement Considerations

Compatible alternatives within the same family include A54SX32-FBGG329 and A54SX32-MBGG329, differing primarily in speed grades and temperature ratings respectively.
