A54SX16A-FG144M

Overview

The A54SX16A-FG144M is a Field Programmable Gate Array from the Actel SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 24,000 system gates and 1,452 logic modules (CLBs). The device supports up to 350 MHz internal performance and features up to 111 user-programmable I/Os in its 144-pin Fine Pitch Ball Grid Array (FBGA) package. It operates with 2.5 V, 3.3 V, and 5 V mixed-voltage I/O standards and includes three global clock networks.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports hot-swap compliant I/Os allowing power-up/down without sequencing requirements for supply voltages.
• Includes configurable weak-resistor pull-up or pull-down capabilities for I/O pins at power-up to ensure deterministic states.
• Features individual output slew rate control and support for multiple voltage standards including 3.3 V/5 V PCI and 5 V TTL.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring nonvolatile configuration without external bitstream memory
• Hot-swap capable electronic designs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. The 'M' suffix indicates military temperature range availability. Confirm RoHS status as the 'G' suffix denotes compliance. Check for discontinuation notices as speed grades may be phased out.

Selection Notes

Select this device for applications needing 24,000 system gates with high-speed internal routing. Ensure the design utilizes the available 111 user I/Os within the FBGA package constraints. Verify that the required I/O voltage levels match the supported 2.5 V, 3.3 V, and 5 V standards. Consider the military temperature grade if operating conditions exceed commercial limits.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are known for their high-density antifuse technology. The SX-A series offers a balance of performance and security, featuring FuseLock technology to prevent reverse engineering. It serves as a drop-in replacement for complex CPLDs in many legacy designs while offering greater flexibility.

Replacement Considerations

Direct replacements within the same package and pinout include other A54SX16A variants with different speed grades or temperature ratings, such as A54SX16A-FG144C or A54SX16A-FG144I. Cross-family migration to newer Microchip FPGA families requires schematic and code redesign due to architectural differences.
