A54SX32A-2FG484I

Overview

The A54SX32A-2FG484I is a Field Programmable Gate Array from the SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and 2,880 logic modules (CLBs). The device supports up to 249 user-programmable I/O pins and includes 1,080 dedicated flip-flops. It operates at a maximum system frequency of 250 MHz with an internal performance of 350 MHz. The component utilizes a 484-pin Fine Pitch Ball Grid Array (FBGA) package and supports industrial temperature grades ranging from -40°C to +85°C.

Feature Summary

• Supports hot-swap compliant I/Os allowing power-up/down without voltage sequencing requirements
• Features deterministic timing through metal-to-metal programmable antifuse interconnect elements
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG)
• Provides configurable I/O standards supporting mixed-voltage operation including 3.3 V, 5 V PCI, and 5 V TTL

Applications

• 66 MHz PCI compliant single-chip solutions
• High-performance digital signal processing designs
• Industrial control systems requiring deterministic timing
• Secure embedded applications utilizing antifuse nonvolatile architecture

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure that the required I/O standards and pin counts align with the design specifications before finalizing procurement orders.

Selection Notes

Select this model for applications requiring high-speed logic with low latency routing resources such as DirectConnect and FastConnect. Consider the 484-pin FBGA package constraints and verify thermal management requirements for the industrial temperature grade during the design phase.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their use of antifuse technology rather than volatile SRAM configuration. The SX-A series offers a balance of high performance and security, making it suitable for designs where data integrity and protection against reverse engineering are critical priorities.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX32A variant, such as the standard or -1 speed grades, provided timing requirements allow. Cross-family migration to newer Microchip FPGA architectures requires schematic and software redesign.
