A54SX08A-2TQG144

Overview

The A54SX08A-2TQG144 is an antifuse-based Field Programmable Gate Array from the Microchip SX-A family. It provides 12,000 system gates and 768 logic modules within a 144-pin Thin Quad Flat Pack (TQFP) package. The device supports up to 113 user-programmable I/Os and operates with supply voltages of 2.5 V, 3.3 V, or 5 V. It features a maximum system performance frequency of 250 MHz and an internal clock speed of 350 MHz. The -2 speed grade indicates approximately 25% faster performance than the standard grade.

Feature Summary

• Utilizes metal-to-metal programmable antifuse technology for permanent configuration without volatile bitstreams.
• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).

Applications

• High-performance digital logic integration replacing complex CPLDs
• PCI-compliant interface designs requiring 66 MHz bus speeds
• Systems requiring deterministic timing and pin-locking capabilities

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm temperature grade and packaging compliance. Ensure that the required speed grade matches the design timing constraints, as older grades may have discontinuation notices. Confirm RoHS status and lead-free packaging availability if environmental compliance is mandatory for the target application.

Selection Notes

Select this component when a nonvolatile FPGA solution with high-speed deterministic routing is required. The SX-A architecture offers 100% resource utilization and pin locking, which simplifies PCB layout compared to SRAM-based FPGAs. Consider the -2 speed grade only if the design requires performance exceeding the standard grade specifications while maintaining the 12,000 gate capacity.

Part Context

This part belongs to the Actel SX-A family, now manufactured by Microchip Technology. The SX-A series is characterized by its antifuse technology, which eliminates the need for external configuration memory. The A54SX08A variant represents the entry-level capacity in terms of system gates within this specific family lineup.

Replacement Considerations

Direct replacements must be sought within the A54SX08A product line with matching speed grades (-2) and package types (TQFP-144). Cross-family migration to newer Microchip FPGA architectures requires significant redesign due to differences in logic structure and programming technology.
