A54SX08A-FPQG208

Overview

The Microsemi A54SX08A-FPQG208 is an antifuse-based Field Programmable Gate Array (FPGA) from the SX-A family. It provides 12,000 system gates and 768 logic modules within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device supports up to 130 user-programmable I/O pins and operates with supply voltages ranging from 2.25V to 5.25V. It features 250 MHz system performance and 350 MHz internal clock speeds. The component includes three global clocks and complies with IEEE 1149.1 Boundary-Scan Testing standards.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse technology for permanent configuration without external memory.
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements or system degradation.
• Supports mixed-voltage operation across 2.5V, 3.3V, and 5V domains with 5V input tolerance and drive strength capabilities.
• Integrated Actel FuseLock security features designed to prevent reverse engineering and unauthorized design access.

Applications

• High-performance digital logic integration replacing complex CPLDs or gate arrays.
• Systems requiring deterministic timing and hot-swappable interface capabilities.
• Applications necessitating secure, nonvolatile configuration without boot-up bitstream interception.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and packaging compliance. The 'I' suffix denotes industrial temperature range (-40°C to +85°C), while 'G' indicates RoHS-compliant packaging. Confirm lead-free status and moisture sensitivity level (MSL 3) requirements prior to procurement to ensure compatibility with assembly processes.

Selection Notes

Select this component when a nonvolatile FPGA architecture is required to eliminate configuration flash memory overhead. Consider the 208-pin PQFP package constraints for PCB layout and thermal management. Ensure the design utilizes the available 130 I/Os and 768 logic modules efficiently, as the antifuse technology does not support reprogramming once fabricated.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which were acquired by Microsemi Corporation. The SX-A series is characterized by its high-density antifuse technology and robust I/O flexibility. It serves as a bridge between standard CPLDs and larger ASIC solutions, offering rapid time-to-market for designs requiring fixed, high-speed logic implementation.

Replacement Considerations

Direct pin-compatible replacements within the same package include other speed grades of the A54SX08A series, such as A54SX08A-1PQ208I or A54SX08A-2PQ208I, provided timing requirements are met. Cross-family replacements require careful evaluation of logic capacity and I/O voltage levels.
