A54SX16A-1TQG144I

Overview

The A54SX16A-1TQG144I 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 is housed in a 144-pin Thin Quad Flat Pack (TQFP) package with a height of 1.4 mm. The Industrial temperature grade (-40°C to +85°C) ensures reliable operation in demanding environments.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Hot-swap compliant I/Os allowing safe insertion into electrically active systems without degrading host reliability.
• Configurable weak-resistor pull-up or pull-down capabilities for I/O pins during power-up to ensure deterministic states.
• Individual output slew rate control on an individual pin basis to manage signal integrity and electromagnetic interference.

Applications

• High-performance digital logic integration requiring deterministic timing and fast execution.
• Systems requiring hot-swappable interface capabilities for maintenance or redundancy.
• Mixed-voltage applications supporting 2.5 V, 3.3 V, and 5 V PCI, TTL, LVTTL, and LVCMOS standards.

Procurement Notes

Verify the specific ordering suffix 'I' confirms the Industrial temperature range (-40°C to +85°C). Confirm the package type matches the 144-pin TQFP specification. Ensure compatibility with Actel Designer software for programming the antifuse structure. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this model for designs requiring approximately 24,000 system gates within a 144-pin footprint. The -1 speed grade offers performance faster than the standard grade. Consider the Industrial temperature rating for environments exceeding commercial limits. Verify that the antifuse technology aligns with non-reconfigurable security requirements.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their high-speed antifuse architecture. The family includes devices ranging from 12,000 to 108,000 system gates. The SX-A series is known for its sea-of-modules architecture and dedicated routing resources like DirectConnect and FastConnect.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other SX-A family members such as A54SX16A-2TQG144I for higher speed grades or A54SX16A-1TQG144 for commercial temperature grades if specifications allow.
