A54SX32A-FPQ208

Overview

The A54SX32A-FPQ208 is a nonvolatile FPGA from the Microchip SX-A family, featuring 48,000 system gates and 174 user-programmable I/Os. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology with a standard speed grade of 250 MHz system performance. The device operates within a voltage range of 2.25 V to 2.75 V at a nominal 2.5 V. It supports mixed-voltage I/O standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2. The component is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Hot-swap compliant I/O architecture allowing safe insertion into active systems without power sequencing requirements or system degradation.
• Deterministic timing performance enabled by DirectConnect and FastConnect routing resources that minimize signal propagation delays.

Applications

• High-performance logic integration replacing complex CPLDs or gate arrays.
• Systems requiring deterministic timing and pin-locking capabilities.
• Applications necessitating hot-swappable interface modules.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm temperature grade and packaging compliance. Confirm current availability status as distribution channels may vary. Ensure design files match the exact speed grade and package type specified in the datasheet before finalizing procurement orders.

Selection Notes

Select this model for designs requiring 48,000 system gates with a 208-pin PQFP footprint. Verify that the required I/O voltage levels align with the supported 2.5 V, 3.3 V, and 5 V standards. Consider the standard speed grade if 250 MHz system performance meets the design constraints.
