A54SX32-2BG329

Overview

The A54SX32-2BG329 is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and supports up to 249 user-programmable I/O pins within a 329-pin Plastic Ball Grid Array (PBGA) package. The device operates at a maximum system performance of 250 MHz with an internal clock frequency capability of 350 MHz. It features mixed-voltage operation supporting 2.5 V, 3.3 V, and 5 V supplies with 5 V input tolerance. The component includes three global clock networks and complies with IEEE Standard 1149.1 for boundary-scan testing.

Feature Summary

• Supports hot-swappable I/O configurations allowing insertion into active systems without power sequencing requirements.
• Integrates patented metal-to-metal programmable antifuse interconnect elements for deterministic timing and low signal impedance.
• Includes dedicated DirectConnect and FastConnect routing resources to minimize propagation delays between logic modules.
• Features FuseLock security technology to prevent reverse engineering and unauthorized design access.

Applications

• 66 MHz PCI compliant single-chip integration solutions
• High-performance state machines and fast counters
• Data path logic requiring deterministic timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm availability status as legacy products may have limited supply or discontinuation notices. Ensure the required speed grade matches the target system performance specifications before procurement.

Selection Notes

Select this device when a nonvolatile FPGA solution with high-speed deterministic timing is required. The SX-A architecture is suitable for designs needing 100% pin locking and resource utilization. Consider the available speed grades if specific timing constraints exceed standard performance levels. Verify that the 329-pin PBGA package fits the target PCB footprint and thermal requirements.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes antifuse technology for permanent configuration. The family ranges from 12,000 to 108,000 system gates, offering various package options including PQFP, TQFP, PBGA, and FBGA. The A54SX32 variant specifically targets applications requiring moderate logic density with high I/O counts.

Replacement Considerations

Direct replacements are not explicitly listed in the provided documentation. Designers migrating from older SX family devices should verify pin compatibility and timing differences. Alternative Microchip or Actel antifuse FPGAs may require schematic and layout modifications due to architectural variations.
