A54SX08-TQG176I

Overview

The A54SX08-TQG176I is an industrial-grade Field Programmable Gate Array from the Microsemi SX-A family, utilizing antifuse technology. It provides 12,000 system gates and 768 logic modules (CLBs). The device supports up to 113 user-programmable I/O pins within a 176-pin Thin Quad Flat Pack (TQFP) package. It operates at a system performance of 250 MHz with internal clock frequencies reaching 350 MHz. The component functions across a supply voltage range of 2.25V to 5.25V and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V I/O standards 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 resources for predictable signal propagation.
• Integrates Actel Secure Programming Technology with FuseLock to prevent reverse engineering and unauthorized design access.

Applications

• Industrial control systems requiring deterministic timing and robust I/O configurations
• Automotive electronics applications compatible with industrial temperature grades
• High-performance logic integration replacing complex programmable logic devices

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C) as defined in the official datasheet. Confirm the package type corresponds to the 176-pin TQFP variant. Ensure compliance with relevant environmental directives such as RoHS if required by the application specifications.

Selection Notes

Select this model when 12,000 system gates and 113 user I/Os are sufficient for the design. The SX-A antifuse architecture offers permanent configuration suitable for high-volume production. Consider the 250 MHz system speed for timing-critical applications. Verify that the 176-pin TQFP footprint matches the PCB layout constraints.

Part Context

This component belongs to the Microsemi SX-A FPGA family, which utilizes metal-to-metal programmable antifuse interconnect elements. The family includes variants like the A54SX16A and A54SX32A with higher gate counts. The SX-A series is designed for low-power, high-performance designs using 0.22 μm / 0.25 μm CMOS process technology.

Replacement Considerations

Cross-reference with other SX-A family members such as A54SX08A-1TQG176I for different speed grades. Check for updated Microchip Technology equivalents if legacy Actel parts are being phased out. Verify pin compatibility and logical resource equivalence before substitution.
