A54SX72A-1FGG256

Overview

The A54SX72A-1FGG256 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 108,000 system gates and 6,036 configurable logic blocks within a 256-pin Fine Pitch Ball Grid Array package. The device supports up to 203 user-programmable I/O pins and operates with supply voltages ranging from 2.25 V to 5.25 V. It achieves a maximum system performance frequency of 250 MHz with internal clock frequencies reaching 350 MHz. The component utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and includes three global routed clocks and one hardwired clock.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and unauthorized design access.
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.

Applications

• High-performance digital signal processing requiring fast execution of complex logic functions
• Systems requiring nonvolatile single-chip solutions without external configuration bitstreams
• Industrial applications needing hot-swappable capabilities and boundary-scan testing compliance

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm temperature grade and packaging compliance. Confirm availability status as legacy products may have limited production runs or discontinuation notices. Ensure design-in tools support the SX-A architecture for proper place-and-route implementation.

Selection Notes

Select this model when high gate density and fast internal clock speeds are required in an antifuse-based FPGA. Consider the 256-pin FBGA package constraints for PCB layout. Evaluate the need for quadrant clocks if large-scale clock distribution is necessary, as this device provides four dedicated quadrant clock networks.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are known for their cost-effective, low-power, and high-performance characteristics. The SX-A series utilizes metal-to-metal programmable antifuse interconnect elements, offering permanent connections once programmed. This family serves as a versatile platform for integrating designs that previously required multiple CPLDs or gate arrays.
