A54SX72A-2FG256

Overview

The A54SX72A-2FG256 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 256-pin Fine Pitch Ball Grid Array (FBGA) package. The device supports up to 203 user-programmable I/O pins and operates with a supply voltage range of 2.25 V to 5.25 V. It delivers a maximum system performance frequency of 250 MHz and an internal performance frequency of 350 MHz. The component utilizes 0.22 μm / 0.25 μm CMOS antifuse technology.

Feature Summary

• Supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/O standards with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated quadrant clock networks for localized high-speed clock distribution across the die.
• Provides nonvolatile single-chip configuration with hardware security features to prevent reverse engineering.

Applications

• High-performance digital signal processing and control logic
• PCI-compliant interface designs requiring 66 MHz system speeds
• Complex state machines and fast counters utilizing direct connect routing
• Secure embedded systems requiring protection against design theft

Procurement Notes

Verify the specific ordering suffix to confirm temperature grade and packaging compliance. The -2 speed grade indicates approximately 25% faster performance than standard. Confirm RoHS status via the G suffix if required. Check current availability as lead times may vary based on manufacturing changes.

Selection Notes

Select this model for applications requiring high gate density and deterministic timing. Ensure the 256-pin FBGA package fits the PCB layout constraints. Verify that the 2.25 V to 5.25 V supply range matches the system power rails. Consider the -2 speed grade if higher throughput is needed compared to standard or -1 grades.
