A54SX32-2TQG144

Overview

The A54SX32-2TQG144 is a Field Programmable Gate Array from the Actel SX-A family, fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 48,000 system gates and 2,880 logic modules (CLBs). The device supports up to 113 user-programmable I/O pins within a 144-pin Thin Quad Flat Pack (TQFP) package. It features an internal performance of 350 MHz with a system performance of 250 MHz. The architecture includes three global clock networks and dedicated routing resources like DirectConnect and FastConnect for deterministic timing.

Feature Summary

• Nonvolatile single-chip solution utilizing metal-to-metal programmable antifuse interconnect elements for permanent low-impedance connections.
• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V I/O standards with configurable weak-resistor pull-up or pull-down at power-up.
• Hot-swap compliant I/Os allow insertion into active systems without degrading host reliability or requiring specific voltage sequencing.
• Includes Boundary-Scan Testing (BST) compliant with IEEE Standard 1149.1 (JTAG) for in-system diagnostic and verification capabilities.

Applications

• High-performance digital signal processing and data path logic requiring fast counters and state machines.
• 66 MHz PCI compliant interfaces and integration of CPLD functionality into single-chip solutions.
• Secure applications utilizing FuseLock technology to prevent reverse engineering and design theft.

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to approximately 25% faster performance than standard speed. Confirm the temperature grade suffix is blank for commercial range (0 to +70°C). Check for RoHS compliance status indicated by the 'G' suffix if required. Ensure the manufacturer source is identified as Microchip Technology following the acquisition of Actel.

Selection Notes

Select this device when 48,000 system gates and 2,880 CLBs are required in a 144-pin TQFP package. The -2 speed grade is suitable for designs needing 250 MHz system performance. Consider the nonvolatile nature of antifuse technology which prevents bitstream interception but requires careful initial programming. Verify I/O voltage requirements match the supported 2.5 V, 3.3 V, and 5 V standards.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which succeeded the original SX series. The SX-A family introduced improved performance with 0.22/0.25 μm CMOS process technology and enhanced I/O flexibility compared to its predecessors. The A54SX32 variant specifically offers 48,000 system gates, positioning it between the A54SX16A and A54SX72A in terms of capacity.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The A54SX32-2TQG144 is a specific speed grade and package combination within the SX-A family. Designers migrating from older SX series devices should verify pin compatibility and timing differences due to the architectural improvements in the SX-A family.
