A54SX32-2TQG176I

Overview

The A54SX32-2TQG176I is a Field Programmable Gate Array from the Actel SX-A family, featuring 48,000 system gates and 2,880 configurable logic blocks. It operates at a maximum system frequency of 250 MHz with an internal performance of 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It is housed in a 176-pin Thin Quad Flat Pack (TQFP) package and is rated for industrial temperature operation ranging from -40°C to +85°C.

Feature Summary

• Supports hot-swap capabilities and power-up/down friendly operation without supply voltage sequencing requirements.
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking.
• Includes unique in-system diagnostic and verification capability via Silicon Explorer II.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering.

Applications

• 66 MHz PCI compliant single-chip solutions
• Low-power, high-performance designs requiring nonvolatile integration
• Systems requiring mixed-voltage operation with 5 V input tolerance

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as packaging options may vary. Check for end-of-life notifications or discontinuation notices prior to procurement.

Selection Notes

Select this model for applications requiring 48,000 system gates within a 176-pin TQFP footprint. Ensure the design accounts for the industrial temperature range (-40°C to +85°C). Verify that the required I/O standards are compatible with the 2.5 V, 3.3 V, and 5 V mixed-voltage support.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using antifuse technology. The family includes devices ranging from 12,000 to 108,000 system gates. The SX-A architecture is designed for cost-effective, low-power, and high-performance applications, offering a nonvolatile single-chip solution.

Replacement Considerations

Consult the official Actel/Microchip compatibility matrix for direct replacements. Consider speed grades -1 or -2 if higher performance is needed, or standard speed if lower cost is prioritized. Verify package availability for alternative suffixes such as BG329 or FG256.
