A54SX32A-1PQG208I

Overview

The A54SX32A-1PQG208I is an antifuse-based Field Programmable Gate Array from the Microchip SX-A family, featuring 48,000 system gates and 174 user-programmable I/Os. It operates within a voltage range of 2.25 V to 5.25 V and supports mixed-voltage I/O standards including 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2. The device utilizes a 0.22 μm / 0.25 μm CMOS process technology and achieves a maximum system performance frequency of 250 MHz with internal clock speeds up to 350 MHz. It is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Supports hot-swap capabilities and power-up/down friendly operation without requiring supply voltage sequencing.
• Features deterministic timing through patented metal-to-metal antifuse interconnects and dedicated routing resources like DirectConnect and FastConnect.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing with flexible or dedicated JTAG pin configurations.
• Provides secure programming via FuseLock technology to prevent reverse engineering and design theft.

Applications

• High-performance logic integration replacing complex programmable logic devices
• PCI-compliant interface designs supporting 66 MHz operations
• Industrial control systems requiring mixed-voltage I/O tolerance

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the 'PQ' package designation matches the required 208-pin Plastic Quad Flat Pack footprint. Ensure the speed grade '1' aligns with the target system timing requirements relative to standard speed grades. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when 48,000 system gates and 174 I/Os are sufficient for the design complexity. The PQFP package is suitable for applications where surface mount quad flat pack compatibility is preferred over ball grid arrays. Consider the 250 MHz system performance limit for high-speed data path requirements. Verify that the antifuse nonvolatile architecture meets the security and configuration needs of the application.

Part Context

This part belongs to the Actel SX-A FPGA family, which utilizes antifuse technology for permanent configuration. The A54SX32A variant specifically offers 48,000 system gates, positioning it between the smaller A54SX16A and larger A54SX72A devices. The SX-A family is characterized by its sea-of-modules architecture and high-density interconnect capabilities.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A such as A54SX32A-PQG208I or A54SX32A-2PQG208I. Different temperature grades like Commercial (C) or Automotive (A) variants may be physically compatible but require verification of thermal specifications.
