A54SX32A-1TQG176

Overview

The A54SX32A-1TQG176 is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates at a maximum internal clock frequency of 350 MHz with a system performance of 250 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/Os for 2.5 V, 3.3 V, and 5 V operation. It is housed in a 176-pin Thin Quad Flat Pack (TQFP) package and supports up to 147 user-programmable I/O pins.

Feature Summary

• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements
• Provides deterministic timing through user-controllable routing resources including DirectConnect and FastConnect
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering
• Features Boundary-Scan Testing compliance with IEEE Standard 1149.1 (JTAG)

Applications

• 66 MHz PCI Compliant Single-Chip Solutions
• High-performance digital signal processing requiring low latency
• Systems requiring nonvolatile configuration without external memory

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Confirm RoHS compliance status as packaging options vary by manufacturing lot. Ensure design tools support the SX-A architecture for proper place-and-route implementation.

Selection Notes

Select this component when 48,000 system gates are required within a 176-pin TQFP footprint. Consider the -1 speed grade for approximately 15% faster performance compared to standard grades. Verify that the target application supports the 0.22/0.25 μm CMOS process and requires antifuse-based nonvolatile configuration.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, high-performance applications using antifuse technology. The SX-A series offers various gate counts and packages, with the A54SX32A providing a mid-range capacity suitable for complex logic integration.

Replacement Considerations

Direct replacements include other speed grades of the A54SX32A in the same TQFP176 package, such as the standard or -2 speed variants. Cross-family migration to Microchip RT or PolarFire devices may be necessary for updated feature sets.
