A54SX32A-TQ144

Overview

The A54SX32A-TQ144 is a Field Programmable Gate Array from the SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates with a maximum internal clock frequency of 350 MHz and supports up to 249 user-programmable I/O pins within a 144-pin Thin Quad Flat Pack (TQFP) package. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and functions at a supply voltage of 2.5 V. It supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V levels.

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 active systems without power sequencing requirements for supply voltages.
• Configurable I/O support for multiple standards including 3.3 V/5 V PCI, 5 V TTL, 3.3 V LVTTL, and 2.5 V LVCMOS2.
• Integrated Boundary-Scan Testing compliant with IEEE Standard 1149.1 (JTAG) for diagnostic and verification capabilities.

Applications

• 66 MHz PCI Compliant Systems
• High-performance digital logic integration replacing complex CPLDs or gate arrays
• Secure designs requiring reverse engineering protection via FuseLock™ technology

Procurement Notes

Verify the specific speed grade suffix associated with the TQ144 package variant, as standard speed grades differ from faster options. Confirm temperature range availability, noting that commercial, industrial, automotive, and military grades exist for this package type. Ensure the ordering code matches the required pin count and I/O configuration for the target application.

Selection Notes

Select this component when 48,000 system gates and 2,880 logic modules are required in a 144-pin surface-mount package. Consider the SX-A architecture's deterministic timing and high-speed routing resources like DirectConnect and FastConnect for critical path optimization. Verify that the 2.5 V core voltage and mixed-voltage I/O capabilities align with the system's power and interface requirements.
