A54SX72A-FG256I

Overview

The A54SX72A-FG256I is an industrial-grade 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 256-pin Fine Pitch Ball Grid Array package. The device supports up to 203 user I/Os and operates at a maximum system frequency of 250 MHz with internal performance reaching 350 MHz. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/O standards.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without damage
• Provides nonvolatile single-chip solution eliminating configuration bitstream interception risks
• Features deterministic timing through unique metal-to-metal programmable antifuse interconnect
• Includes boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG)

Applications

• High-performance digital signal processing requiring low latency
• Industrial control systems necessitating mixed-voltage I/O compatibility
• Secure embedded applications utilizing antifuse-based anti-tampering architecture

Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required temperature grade and packaging specifications. Ensure compliance with export regulations applicable to programmable logic devices in your jurisdiction prior to transaction completion.

Selection Notes

Select this model when design requirements demand high gate density combined with robust security features inherent to antifuse technology. Consider the 256-pin FBGA package constraints during PCB layout planning. Verify that the target application environment aligns with the specified industrial temperature range capabilities of the device variant.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their use of metal-to-metal antifuse programming technology. The SX-A series provides a cost-effective alternative to volatile FPGA solutions while offering permanent configuration and enhanced intellectual property protection against reverse engineering attacks.

Replacement Considerations

Direct functional replacements within the same package and pinout may include other speed grades of the A54SX72A series, such as A54SX72A-1FG256I or A54SX72A-2FG256I, provided timing requirements are met. Cross-family migration requires careful analysis of architectural differences between antifuse and SRAM-based FPGAs.
