A54SX08-PQ208

Overview

The A54SX08-PQ208 is a nonvolatile Field Programmable Gate Array from the SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 system gates and 768 logic modules within a 208-pin Plastic Quad Flat Pack (PQFP) package. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. It features up to 130 user-programmable I/Os, three global clock networks, and hot-swap compliant I/Os that allow power-up/down without sequencing requirements.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V drive strength and input tolerance.
• Hot-swap compliant I/O architecture allows insertion into active systems without degrading host reliability or requiring voltage sequencing.
• Includes configurable weak-resistor pull-up or pull-down capabilities for I/O pins during power-up to ensure deterministic states.

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces including PCI compliance
• DSP and co-processor functions

Procurement Notes

Verify the specific ordering suffix to confirm temperature grade and packaging compliance. The base model designation indicates the core capacity and package type, but additional characters define speed grade, industrial or commercial rating, and lead-free status. Confirm availability through authorized Microchip distributors as this component may be subject to lifecycle transitions.

Selection Notes

Select the appropriate speed grade suffix based on required timing performance relative to the standard speed. Ensure the temperature grade matches the operational environment, choosing between commercial, industrial, automotive, or military ratings. Verify pin compatibility with the 208-pin PQFP footprint and confirm that the 12,000 gate capacity meets the design logic density requirements.

Part Context

This component belongs to the Actel SX-A FPGA family, which offers high-performance logic integration using antifuse technology. The SX-A series is designed to replace multiple complex programmable logic devices (CPLDs) and gate arrays in a single chip. The A54SX08 variant represents the entry-level capacity within the 208-pin package options of this family.

Replacement Considerations

Compatible substitutes include other members of the SX-A family such as the A54SX16A or A54SX32A for increased capacity, provided the pinout remains compatible. Cross-family replacements require verification of architectural differences and programming tool support.
