A54SX72A-FGG256M

Overview

The A54SX72A-FGG256M is a Field Programmable Gate Array from the SX-A family, featuring 108,000 system gates and 6,036 logic modules. It operates within a supply voltage range of 2.25V to 5.25V and supports up to 360 user-programmable I/O pins. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology, enabling internal performance specifications of 350 MHz and system performance of 250 MHz. It is housed in a 256-pin Fine Pitch Ball Grid Array (FG) package with a 1.0 mm pitch. The -M suffix indicates a military temperature grade operating between -55°C and +125°C.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength.
• Features hot-swap compliant I/Os allowing power-up/down without sequencing requirements for supply voltages.
• Includes dedicated quadrant clock networks for localized high-speed clock distribution.
• Provides boundary-scan testing compliance with IEEE Standard 1149.1 (JTAG).

Applications

• High-performance digital signal processing systems requiring deterministic timing.
• Industrial control applications necessitating wide temperature range operation.
• Military aerospace electronics requiring MIL-STD-883 Class B qualification.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure that the military grade (-M) designation aligns with project environmental requirements. Confirm availability through authorized Microchip Technology distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when designs require high gate density with nonvolatile configuration and robust security features. Consider the -M variant for environments exceeding commercial or industrial temperature limits. Evaluate the 256-pin FBGA package constraints regarding PCB layout and thermal management during the initial design phase.
