A54SX16-2TQ176I

Overview

The A54SX16-2TQ176I is a Field Programmable Gate Array from the SX-A family, featuring 1452 Configurable Logic Blocks and approximately 24,000 system gates. It operates at a maximum internal clock frequency of 350 MHz with a typical system performance of 250 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 compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing for superior diagnostic capabilities.

Applications

• High-performance digital logic integration requiring low latency
• Systems necessitating hot-swappable interface capabilities
• Industrial control applications operating within extended temperature ranges

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with Actel Designer software versions supporting the SX-A architecture. Confirm RoHS compliance status if required by your manufacturing specifications.

Selection Notes

Select this model when 24,000 system gates are sufficient for the design complexity. The -2 speed grade offers approximately 25% faster performance than standard grades. Verify that the 176-pin TQFP package fits the PCB footprint constraints and thermal management requirements of the target application.

Part Context

This component belongs to the Actel SX-A FPGA family, which uses nonvolatile antifuse technology. Unlike volatile FPGAs, it does not require an external configuration memory device. The family includes variants with different gate counts and package options, catering to various performance and density needs.

Replacement Considerations

Check for updated Microchip Technology equivalents in the SmartFusion or IGLOO families. Verify pinout compatibility and logic resource equivalence before substitution. Note that newer technologies may use SRAM instead of antifuse, altering configuration requirements.
