A54SX16A-1FG256

Overview

The A54SX16A-1FG256 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology (formerly Actel). It features 24,000 system gates and 180 user-programmable I/O pins. The device operates at a maximum frequency of 263 MHz with a supply voltage range of 2.25 V to 2.75 V. It utilizes a 0.22 μm / 0.25 μm CMOS antifuse process technology. The component is housed in a 256-pin Fine Pitch Ball Grid Array (FBGA) package and supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V I/O standards 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 networks (HCLK, CLKA, CLKB) and boundary-scan testing compliance with IEEE Standard 1149.1.

Applications

• High-performance digital logic integration requiring deterministic timing and fast signal propagation.
• Systems requiring hot-swappable capabilities or power-up/down friendly operation without voltage sequencing.
• Secure designs utilizing FuseLock technology to prevent reverse engineering and design theft.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Confirm RoHS compliance status as packaging options may vary. Check for discontinuation notices or product change notifications regarding availability and manufacturing sources.

Selection Notes

Select this model for applications requiring 24,000 system gates and 180 I/Os within a 256-pin FBGA footprint. Ensure the design accommodates the 2.5 V core voltage and supports the required I/O standards. Verify that the antifuse programming requirements align with the production workflow and security needs.
