A54SX08A-TQG144I

Overview

The A54SX08A-TQG144I is a nonvolatile Field Programmable Gate Array from the Microchip SX-A family, featuring 12,000 system gates and 768 logic modules. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 144-pin Thin Quad Flat Pack (TQFP) package with 113 user I/Os. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V, providing 5 V input tolerance. Internal performance reaches up to 350 MHz, while system performance is rated at 250 MHz.

Feature Summary

• Supports hot-swap capabilities for most I/O standards, allowing safe insertion into active systems without power sequencing requirements.
• Features deterministic timing through patented metal-to-metal antifuse interconnects and dedicated routing resources like DirectConnect.
• Includes IEEE 1149.1 compliant Boundary-Scan Testing with flexible JTAG pin configurations for in-system diagnostics.

Applications

• High-performance digital logic integration requiring low-power consumption
• PCI-compliant interface designs operating at 66 MHz
• Secure embedded applications utilizing FuseLock technology

Procurement Notes

Verify the specific ordering suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the 'G' suffix indicates RoHS compliance if required by environmental regulations. Ensure the TQFP-144 package dimensions match the target PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this component when 12,000 system gates are sufficient for the design logic. Choose the TQFP-144 package if surface-mount space allows for a larger footprint compared to BGA options. Verify that the 113 available I/O pins meet the interface requirements for the target application.

Part Context

This part belongs to the Actel SX-A FPGA family, which utilizes antifuse technology for permanent configuration. The A54SX08A variant represents the entry-level capacity within this series, offering a balance of performance and resource density for cost-sensitive high-speed applications.

Replacement Considerations

Direct replacements include other speed grades within the A54SX08A series, such as the standard or faster variants, provided they fit the same TQFP-144 package. Cross-family migration to newer Microchip FPGA architectures requires significant design re-validation due to architectural differences.
