A54SX16A-1TQ144I

Overview

The A54SX16A-1TQ144I is a Field Programmable Gate Array from the SX-A family, featuring 24,000 system gates and 1,452 logic modules. It operates at a maximum system frequency of 250 MHz with an internal performance of 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It contains up to 990 dedicated flip-flops and provides 113 user-programmable I/O pins. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package and is rated for industrial temperature operation ranging from -40°C to +85°C.

Feature Summary

• Supports hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements.
• Features deterministic timing through unique local routing resources like DirectConnect and FastConnect.
• Includes Actel FuseLock security technology to prevent reverse engineering and unauthorized design access.
• Provides boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).

Applications

• High-performance digital signal processing requiring low latency
• Industrial control systems operating in harsh environments
• Communication interface protocols such as PCI compliance

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the 'G' suffix status if RoHS compliance is required, as the base part number may denote standard packaging. Ensure the TQFP-144 package dimensions match the PCB footprint specifications provided in the datasheet pinout diagrams.

Selection Notes

Select this model when 24,000 system gates are sufficient for the design logic density. The -1 speed grade offers approximately 15% faster performance than the standard grade. Consider the 144-pin TQFP package constraints regarding thermal dissipation and pin availability for the required 113 I/O connections.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their nonvolatile antifuse technology. The family includes devices ranging from 12,000 to 108,000 system gates. The A54SX16A variant specifically targets applications needing a balance between logic capacity and high-speed performance within a compact form factor.

Replacement Considerations

Public confirmed substitute part numbers include A54SX16A-FGG144 and A54SX16ATQ144IX79. Verify that alternative packages or speed grades meet the specific timing and environmental requirements of the original design.
