A54SX16P-1TQG176I

Overview

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

Feature Summary

• Nonvolatile antifuse architecture providing single-chip integration without external configuration memory
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements
• Deterministic timing through patented metal-to-metal interconnects and dedicated routing resources
• Integrated boundary-scan testing compliant with IEEE Standard 1149.1 for diagnostic verification

Applications

• Industrial control systems requiring deterministic logic processing
• Embedded interfaces supporting mixed-voltage communication protocols
• Spacecraft avionics data acquisition and control units
• Downhole multiphysics micro-measurement systems for drilling engineering

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct channels. Confirm RoHS compliance status and specific packaging variants prior to ordering. Check for end-of-life notifications or discontinuance updates as this series may have limited availability. Ensure design compatibility with current supply chain constraints.

Selection Notes

Select this model when 24,000 system gates and 176-pin TQFP packaging are required. Verify that the -1 speed grade meets the 250 MHz system performance target. Confirm industrial temperature range suitability for the operating environment. Evaluate pin count requirements against the 147 available user I/Os for interface needs.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The family offers scalable gate counts ranging from 12,000 to 108,000 system gates. The SX-A series is designed for low-power, high-performance applications requiring nonvolatile configuration and secure programming capabilities.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider evaluating other devices within the A54SX16A series with different package options or speed grades if pinout compatibility allows.
