A54SX32A-2PQG208I

Overview

The A54SX32A-2PQG208I is an antifuse-based Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It provides 48,000 system gates and supports up to 174 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device operates at a standard supply voltage of 2.5 V, with a minimum operating voltage of 2.25 V and a maximum of 2.75 V. It features a maximum system performance frequency of 250 MHz and an internal clock speed of 350 MHz. The component is rated for industrial temperature applications, functioning reliably between -40°C and +85°C.

Feature Summary

• Utilizes metal-to-metal programmable antifuse technology for nonvolatile configuration without external memory requirements.
• Supports mixed-voltage I/O operation across 2.5 V, 3.3 V, and 5 V domains with inherent 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing constraints.
• Includes dedicated routing resources such as DirectConnect and FastConnect for deterministic, low-latency signal propagation.

Applications

• High-performance logic integration replacing complex CPLDs or gate arrays in embedded systems.
• Industrial control interfaces requiring robust I/O standards and mixed-voltage compatibility.
• Secure hardware designs utilizing FuseLock technology to prevent reverse engineering and design theft.

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and temperature grade accuracy. Confirm RoHS compliance status and lead-free packaging availability through official Microchip channels prior to procurement. Ensure design files are compatible with the Actel Designer software suite for proper programming and verification.

Selection Notes

Select this model when 48,000 system gates and 208-pin form factor are required for industrial environments. The -2 speed grade offers approximately 25% faster performance than the standard variant. Verify that the PQFP package fits the PCB footprint constraints and that the 2.5 V core voltage aligns with the system power architecture.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which leverages 0.22 μm / 0.25 μm CMOS antifuse technology. The family is characterized by high-density logic modules, global clock networks, and strong security features. The A54SX32A specifically bridges the capacity gap between lower-density devices like the A54SX16A and higher-density options like the A54SX72A.

Replacement Considerations

Direct pin-compatible replacements within the same package and speed grade may include other variants from the A54SX32A series, such as the A54SX32A-1PQG208I or A54SX32A-PQG208I, provided the speed grade requirements are met. Cross-family migration to newer Microchip FPGA architectures requires schematic and code redesign.
