A54SX32A-BGG329M

Overview

The A54SX32A-BGG329M is a Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates with an internal clock frequency of up to 350 MHz and supports mixed-voltage I/O at 2.5 V, 3.3 V, and 5.0 V. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology for nonvolatile configuration. It includes 249 user-programmable I/Os, three global clocks, and complies with IEEE 1149.1 Boundary-Scan Testing standards.

Feature Summary

• Supports hot-swap operations and power-up/down without supply voltage sequencing requirements
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect
• Features Actel FuseLock security technology to prevent reverse engineering and design theft
• Enables 100% resource utilization and pin locking for concurrent PCB development

Applications

• 66 MHz PCI compliant designs
• Low-power high-performance single-chip solutions
• Systems requiring mixed-voltage operation (2.5 V, 3.3 V, 5.0 V)
• Applications needing secure, nonvolatile FPGA implementation

Procurement Notes

Verify the specific ordering suffix 'M' against official Microchip documentation to confirm military temperature grade (-55°C to +125°C) and lead-free packaging status. Confirm current availability as legacy antifuse products may have limited production runs or discontinuation notices.

Selection Notes

Select this part for applications requiring deterministic performance and high I/O density in a BGA package. Ensure the design leverages the 249 available user I/Os and matches the required speed grade for the target system frequency. Verify that the 0.22/0.25 micron process meets the environmental and reliability constraints of the final application.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are known for their antifuse-based nonvolatile architecture. The SX-A series bridges the gap between CPLDs and larger FPGAs, offering high performance with low power consumption. The A54SX32A variant specifically targets mid-range logic density requirements.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A series (e.g., A54SX32A-FG256 variants if pin-compatible). Cross-family migration to newer Microchip PolarFire or SmartFusion devices requires significant redesign due to architectural differences.
