A54SX08A-2TQ144

Overview

The A54SX08A-2TQ144 is a Field Programmable Gate Array from the SX-A family, manufactured by Microchip Technology. It features 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/O pins and operates with supply voltages of 2.5 V, 3.3 V, or 5 V. It delivers a maximum system performance frequency of 250 MHz and an internal clock frequency of 350 MHz. The component utilizes antifuse technology for nonvolatile configuration.

Feature Summary

• 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 boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).
• Provides deterministic timing through unique local routing resources like DirectConnect and FastConnect.

Applications

• Integration of 66 MHz PCI compliant designs on a single chip.
• High-performance state machines and fast counters requiring deterministic timing.
• Data path logic applications utilizing low-capacitance interconnect structures.

Procurement Notes

Verify the specific speed grade suffix '2' corresponds to approximately 25% faster performance than standard speed when sourcing replacements. Confirm that the TQFP package variant matches the required thermal and mechanical constraints for the target PCB layout. Ensure compatibility with Actel Designer software versions supporting the SX-A family architecture.

Selection Notes

Select this model for designs requiring 12,000 system gates with high-speed performance characteristics. Consider the -2 speed grade if timing closure requires approximately 25% faster switching than the standard grade. Verify that the 144-pin TQFP package fits the available board space and that the operating temperature range meets environmental specifications.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using 0.22 μm / 0.25 μm CMOS antifuse technology. The SX-A series is designed to replace complex CPLDs and gate arrays by offering high performance and low power consumption in a single-chip solution. The A54SX08A represents the entry-level capacity within this specific product line.
