A54SX32A-2BGG329

Overview

The A54SX32A-2BGG329 is a Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum frequency of 250 MHz with an internal performance of 350 MHz. The device supports up to 249 user-programmable I/Os and includes 1,080 dedicated flip-flops. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and accepts supply voltages of 2.5 V, 3.3 V, or 5 V. The component is housed in a 329-pin Plastic Ball Grid Array (PBGA) package.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes deterministic timing architecture with DirectConnect and FastConnect routing for predictable signal propagation.
• Provides nonvolatile single-chip configuration with Actel Secure Programming Technology to prevent reverse engineering.

Applications

• 66 MHz PCI compliant interface integration
• High-performance state machine implementation
• Fast counter and data path logic design

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to the required performance level, as it indicates approximately 25% faster operation than standard speed. Confirm the temperature grade 'I' meets industrial operating range requirements. Ensure the PBGA329 package footprint matches the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this model when 48,000 system gates and 249 I/Os are sufficient for the design. The -2 speed grade is appropriate for designs requiring higher clock frequencies up to 250 MHz. Verify that the 329-pin BGA package is compatible with the assembly process and thermal management strategy of the target application.

Part Context

This part belongs to the SX-A family of FPGAs, which uses antifuse technology for permanent configuration. The A54SX32A variant provides a balance of logic density and I/O count within the family, positioned between the A54SX16A and A54SX72A devices in terms of resource capacity.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade are not explicitly listed in the provided documentation. Consider checking the broader SX-A family datasheet for alternative packages or speed grades if form-factor changes are permissible.
