A54SX32A-1PQG208

Overview

The A54SX32A-1PQG208 is a Field Programmable Gate Array from the Microchip Technology SX-A family, featuring 48,000 system gates. It utilizes antifuse technology and operates with a standard supply voltage of 2.5 V, supporting a range of 2.25 V to 2.75 V. The device provides 174 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP) package. It supports mixed-voltage operation including 3.3 V and 5 V I/O standards with 5 V input tolerance. The -1 speed grade indicates performance approximately 15% faster than the standard speed variant.

Feature Summary

• Supports hot-swap capabilities for most I/O configurations, allowing safe insertion into active systems without power sequencing requirements.
• Features deterministic timing through patented metal-to-metal antifuse interconnects and dedicated routing resources like DirectConnect and FastConnect.
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG) for diagnostic and verification purposes.
• Provides configurable weak-resistor pull-up or pull-down options for I/O pins during power-up to ensure known states.

Applications

• High-performance logic integration requiring nonvolatile single-chip solutions
• Systems requiring hot-swappable interface capabilities
• Applications needing mixed-voltage I/O support (2.5 V, 3.3 V, 5 V)
• Designs requiring deterministic timing and high-speed signal propagation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging details. Ensure compatibility with Actel Designer software versions for programming and configuration. Check for any product discontinuation notices or lifecycle changes associated with the SX-A family before finalizing procurement plans.

Selection Notes

Select this component when 48,000 system gates are required in a 208-pin PQFP package. The -1 speed grade is suitable for designs needing moderate performance improvements over standard speeds. Consider the automotive or military temperature grades if operating conditions exceed commercial limits. Verify that the antifuse technology aligns with the project's reprogrammability constraints.

Part Context

This part belongs to the SX-A FPGA family, which uses antifuse technology for permanent configuration. The A54SX32A designation indicates 48,000 system gates. The PQG suffix denotes a lead-free PQFP package. This family offers high-density logic with low power consumption and robust security features against reverse engineering.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A series, such as the standard speed version or higher speed variants, provided timing requirements are met. Cross-family migration may require schematic and layout modifications due to architectural differences.
