A54SX32A-FFG256

Overview

The A54SX32A-FFG256 is a nonvolatile FPGA from the SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and supports up to 203 user I/Os within a 256-pin Fine Pitch Ball Grid Array (FBGA) package. The device operates at a standard speed grade with internal clock frequencies reaching 350 MHz. It features three global clock networks and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports hot-swap capabilities and power-up/down friendly operation where supply voltage sequencing is not required.
• Includes dedicated routing resources such as DirectConnect and FastConnect to minimize signal propagation delays and ensure deterministic timing.
• Compliant with IEEE Standard 1149.1 (JTAG) for boundary-scan testing and includes Actel Secure Programming Technology.

Applications

• High-performance logic integration requiring deterministic timing and fast execution of complex functions.
• Systems requiring hot-swappable components or cold-sparing configurations.
• Applications needing mixed-voltage I/O interfacing with 3.3 V, 5 V PCI, or TTL standards.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm that the FFG256 designation corresponds to the correct pin count and package dimensions for your PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a nonvolatile FPGA architecture is preferred over volatile SRAM-based devices to eliminate configuration boot times. Ensure the design utilizes the available global clock networks and considers the specific I/O voltage requirements supported by the SX-A family for mixed-voltage compatibility.

Part Context

This part belongs to the Microchip (formerly Actel) SX-A family of FPGAs. The 'A54SX32A' indicates the device capacity of 48,000 system gates. The 'FFG' suffix denotes the 1.0 mm Fine Pitch Ball Grid Array package type, and '256' specifies the 256-pin variant. This family is characterized by its antifuse technology and high-speed performance.

Replacement Considerations

Direct replacements must match the 48,000 system gate capacity and 256-pin FBGA package. Verify compatibility with existing Actel Designer software tools. Consider the discontinued status of -3 speed grades if upgrading speed is necessary.
