A54SX16A-1FGG144I

Overview

The A54SX16A-1FGG144I 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 operates within an industrial temperature range of -40°C to +85°C. It utilizes a 144-pin Fine Pitch Ball Grid Array (FBGA) package with 111 user-programmable I/Os. Key specifications include 924 dedicated flip-flops, three global clock networks, and support for mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements or system degradation.
• Deterministic timing architecture featuring DirectConnect and FastConnect routing resources for predictable signal propagation.
• Integrated security features including FuseLock technology to prevent reverse engineering and unauthorized design access.

Applications

• High-performance digital logic integration requiring deterministic timing and pin-locking capabilities.
• Systems requiring hot-swappable interface components with mixed-voltage I/O tolerance.
• Secure embedded applications necessitating nonvolatile configuration and protection against reverse engineering.

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C) and 'FG' denotes the 1.0 mm Fine Pitch Ball Grid Array package. Confirm RoHS compliance status via the manufacturer's current documentation, as packaging options may vary. Ensure the design accounts for the discontinued -3 speed grades if upgrading from older variants.

Selection Notes

Select this component when 24,000 system gates and 111 user I/Os are required in a compact 144-pin FBGA footprint. The Industrial temperature grade is suitable for environments exceeding commercial limits. Consider the 0.22/0.25 μm process technology for low-power operation and the availability of dedicated flip-flops for synchronous designs.
