A54SX16A-FGG144M

Overview

The A54SX16A-FGG144M is a Field Programmable Gate Array from the SX-A family, featuring 24,000 system gates and 1,452 logic modules. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology with a standard speed grade. The device operates at a maximum system frequency of 250 MHz and an internal performance of 350 MHz. It supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V, with 5 V input tolerance. The component is housed in a 144-pin Fine Pitch Ball Grid Array (FGG144) package with a 1.0 mm pitch.

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.
• Provides deterministic user-controllable timing with up to 100% resource utilization and 100% pin locking capabilities.
• Includes Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• High-performance digital logic integration requiring deterministic timing
• Systems requiring nonvolatile configuration without external bitstream memory
• Mixed-voltage interface designs supporting 2.5 V, 3.3 V, and 5 V standards

Procurement Notes

Verify the specific ordering suffix 'M' against official Microchip documentation to confirm military temperature grade specifications. Ensure compatibility with the 1.0 mm fine pitch ball grid array footprint during PCB layout. Confirm RoHS compliance status if required by local regulations. Validate that the standard speed grade meets the target system clock requirements.

Selection Notes

Select this model for applications requiring 24,000 system gates within a compact 144-pin form factor. Consider the standard speed grade for cost-sensitive designs where 250 MHz system performance is sufficient. Evaluate the need for military-grade temperature range indicated by the suffix before finalizing the part number. Compare against other SX-A variants if higher gate counts or different package types are necessary.
