A54SX16P-PQG208M

Overview

The A54SX16P-PQG208M is a Field Programmable Gate Array from the Actel SX-A family, manufactured by Microchip Technology. It features 24,000 system gates and 175 user I/Os within a 208-pin PQFP package. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. Operating temperatures range from -55°C to +125°C for the military grade. Maximum system performance reaches 250 MHz with internal clock frequencies up to 350 MHz.

Feature Summary

• Nonvolatile antifuse architecture providing single-chip solution without configuration bitstreams
• Hot-swap compliant I/Os allowing safe insertion into active systems
• Configurable weak-resistor pull-up or pull-down for deterministic power-up states
• Support for IEEE 1149.1 Boundary-Scan Testing via JTAG interface

Applications

• Military and aerospace systems requiring wide temperature ranges
• Industrial control applications needing hot-swappable interfaces
• High-performance logic integration replacing complex CPLDs

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as packaging suffixes may vary. Check for End-of-Life notifications or discontinuance notices prior to procurement. Ensure supply chain stability due to potential obsolescence of legacy FPGA families.

Selection Notes

Select this model for designs requiring 24,000 system gates in a 208-pin PQFP form factor. Choose the M suffix for military-grade temperature specifications (-55°C to +125°C). Verify voltage requirements against the 2.5 V, 3.3 V, and 5 V mixed-voltage capabilities. Consider pin count constraints relative to the 175 available user I/Os.

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 SX-A series is designed for low-power, high-performance applications. Microchip Technology acquired Actel, continuing support for these nonvolatile FPGA solutions.

Replacement Considerations

Direct replacements are limited due to the specific antifuse architecture and package type. Evaluate other SX-A family members like A54SX32A for higher capacity. Consider modern Microchip PolarFire or IGLOO families for new designs, noting significant architectural differences.
