A54SX72A-2FG484

Overview

The A54SX72A-2FG484 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 logic modules within a 484-pin Fine Pitch Ball Grid Array (FBGA) package with a 1.0 mm pitch. The device supports up to 360 user-programmable I/O pins and operates on a 0.22 μm / 0.25 μm CMOS antifuse process technology. It delivers 250 MHz system performance and 350 MHz internal performance. The part number indicates a standard speed grade (-2), commercial temperature range (0°C to +70°C), and RoHS compliant packaging.

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 input tolerance and drive strength.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability.
• Includes dedicated clock resources such as HCLK, CLKA, CLKB, and quadrant clocks for deterministic timing.

Applications

• High-performance digital signal processing requiring fast counters and state machines
• PCI-compliant interface designs operating at 66 MHz
• Secure embedded applications protected by Actel Secure Programming Technology

Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Ensure the design tool suite supports the SX-A architecture for proper place-and-route implementation. Confirm that the selected package variant matches the required pin count and thermal characteristics for the target application environment.

Selection Notes

Select this device when high gate density and deterministic timing are required for complex logic functions. Consider the -2 speed grade for approximately 25% faster performance compared to the standard grade. Evaluate the 484-pin FBGA package for its suitability regarding board space and routing complexity in surface-mount applications.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which were originally developed by Actel Corporation before being acquired by Microsemi and subsequently Microchip Technology. The SX-A series is characterized by its antifuse-based nonvolatile configuration and high-speed metal-to-metal interconnect architecture, distinguishing it from volatile SRAM-based FPGAs.
