A54SX32-TQ144M

Overview

The A54SX32-TQ144M is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2880 logic modules. It operates at a maximum internal frequency of 350 MHz with a system performance of 250 MHz. The device supports up to 113 user-programmable I/Os and includes dedicated flip-flops for sequential logic. Fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology, it accommodates mixed-voltage operation at 2.5 V, 3.3 V, and 5.0 V with 5.0 V input tolerance. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• Supports hot-swap capabilities and power-up/down friendly operation without supply voltage sequencing requirements.
• Provides deterministic, user-controllable timing through patented metal-to-metal programmable antifuse interconnect elements.
• Includes unique in-system diagnostic and verification capability utilizing Silicon Explorer II technology.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and design theft.

Applications

• 66 MHz PCI compliant single-chip integration solutions
• High-performance state machines and fast counters requiring deterministic timing
• Data path logic applications demanding low signal impedance and high speed

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Confirm availability status as legacy antifuse devices may have limited production runs or end-of-life notifications. Ensure the selected variant matches the required operating temperature range and pin count specifications for the target application.

Selection Notes

Select this model when 48,000 system gates and 113 I/Os are required within a 144-pin TQFP footprint. Consider the SX-A family architecture for designs needing nonvolatile configuration without external memory. Evaluate the 2.5 V, 3.3 V, and 5.0 V mixed-voltage support if interfacing with diverse logic standards is necessary.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which utilizes antifuse technology for permanent configuration. The SX-A series bridges the gap between CPLDs and gate arrays by offering high performance and low power consumption. Microchip Technology acquired Actel, continuing support for these nonvolatile FPGA platforms.

Replacement Considerations

Direct replacements within the same package and capacity include other speed grades of the A54SX32A series such as A54SX32-1TQ144M or A54SX32-2TQ144M. Verify that the alternative speed grade meets the timing requirements of the original design.
