A54SX16-1PQ208I

Overview

The Microsemi A54SX16-1PQ208I is an industrial-grade Field Programmable Gate Array from the SX-A family, housed in a 208-pin Plastic Quad Flat Pack (PQFP). It provides 24,000 system gates and supports up to 175 user-programmable I/O pins. The device operates within a voltage range of 2.25 V to 2.75 V and functions reliably across temperatures from -40°C to +85°C. Featuring a -1 speed grade, it delivers approximately 15% faster performance than standard variants, with internal clock frequencies reaching 350 MHz.

Feature Summary

• Nonvolatile antifuse architecture providing permanent configuration without external memory
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Deterministic timing through metal-to-metal programmable interconnect elements
• Integrated boundary-scan testing compliant with IEEE Standard 1149.1

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interfaces requiring mixed-voltage operation
• DSP and co-processor functions in industrial environments

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and package type. Confirm lead-free status if RoHS compliance is required for the assembly process. Check current product lifecycle status as older FPGA families may have limited availability or end-of-life notifications.

Selection Notes

Select this model when industrial temperature stability (-40°C to +85°C) is mandatory. The -1 speed grade offers higher performance than standard parts while maintaining compatibility with the PQFP208 footprint. Ensure design requirements align with the 24,000 system gate capacity and available I/O count for the target application.

Part Context

This component belongs to the Actel/Microsemi SX-A family of FPGAs, which utilizes 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series is designed for cost-effective, high-performance single-chip solutions that replace multiple CPLDs or FPGAs. The A54SX16 variant sits between the smaller A54SX08A and larger A54SX32A devices in terms of logic density.

Replacement Considerations

Compatible substitutes within the same package include other speed grades of the A54SX16A series, such as the standard speed A54SX16-PQ208I or the faster A54SX16-2PQ208I. Verify pinout compatibility and electrical specifications before substitution.
