A54SX16P-2TQG176I

Overview

The A54SX16P-2TQG176I is a Field Programmable Gate Array from the Actel SX-A family, manufactured by Microchip Technology. It features 24,000 system gates and 1,452 logic modules within a 176-pin Thin Quad Flat Pack (TQFP) package. The device supports an internal performance of 350 MHz with a maximum clock frequency of 250 MHz. It operates at 2.5 V, 3.3 V, or 5 V with mixed-voltage I/O support and includes 147 user-programmable I/Os. The Industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Features deterministic timing through unique local routing resources like DirectConnect and FastConnect for predictable signal propagation.
• Includes IEEE 1149.1 Boundary-Scan Testing (JTAG) compliance for superior diagnostic and verification capabilities.
• Provides nonvolatile antifuse technology that prevents reverse engineering and design theft via FuseLock security.

Applications

• High-performance digital logic integration requiring deterministic timing.
• Systems requiring hot-swappable interface capabilities.
• Industrial applications needing robust boundary-scan testing and diagnostics.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, speed grade, and temperature range. Ensure compatibility with existing PCB footprints for the 176-pin TQFP configuration. Confirm RoHS compliance status if required by project specifications. Cross-reference the part number with current product lifecycle notifications to verify availability and obsolescence status.

Selection Notes

Select this component when designs require high-speed logic processing with up to 24,000 system gates. The SX-A architecture is suitable for replacing multiple CPLDs or gate arrays. Consider the 176-pin TQFP package for space-constrained industrial applications. Verify that the 250 MHz system performance meets the timing constraints of the target application.

Part Context

This device belongs to the Actel SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The family offers a single-chip solution for low-power, high-performance designs. The SX-A series is known for its sea-of-modules architecture and metal-to-metal programmable interconnect elements.

Replacement Considerations

Compatible devices within the same family include A54SX16A-2TQG176I and A54SX16P-2TQ176M. Verify pinout compatibility and electrical characteristics before substitution. Check datasheet revisions for any architectural changes between P and A series variants.
