A54SX08A-TQG144A

Overview

The A54SX08A-TQG144A is an automotive-grade Field Programmable Gate Array (FPGA) from the SX-A family, manufactured by Microchip Technology. It features a sea-of-modules architecture with 768 combinatorial cells and 256 register cells, providing 12,000 typical system gates. The device operates within a voltage range of 2.25 V to 3.6 V and supports internal clock frequencies up to 250 MHz. It utilizes a 0.22 µ CMOS process technology and includes hot-swap compliant I/Os. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package and is designed for extended temperature ranges suitable for automotive applications.

Feature Summary

• Nonvolatile antifuse-based architecture ensuring deterministic timing and protection against reverse engineering via FuseLock technology.
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Configurable I/O modules supporting multiple voltage standards including 3.3V PCI, LVTTL, and LVCMOS2.
• Integrated boundary scan testing (BST) compliant with IEEE Standard 1149.1 for diagnostic and verification capabilities.

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• Performance-intensive logic integration replacing CPLDs

Procurement Notes

Verify the specific ordering suffix 'A' confirms the automotive temperature grade (-40°C to 125°C). Confirm that the TQG144 designation corresponds to the 144-pin TQFP package. Ensure compliance with RoHS packaging requirements if indicated by the 'G' suffix in related part numbers, though this specific suffix is not present here. Check for export administration regulations as these are specialized semiconductor components.

Selection Notes

Select this device when designing for automotive environments requiring operation up to 125°C. The 12,000 gate capacity is suitable for moderate complexity logic functions. Consider the 144-pin TQFP package constraints regarding PCB space and thermal management. Verify that the 250 MHz internal performance meets the timing requirements of the target application before finalizing the design.

Part Context

This component belongs to the Actel SX-A Automotive Family FPGAs. It shares architectural similarities with other devices in the series such as the A54SX16A and A54SX32A, differing primarily in logic module count and I/O capacity. The SX-A family is characterized by its sea-of-modules structure and nonvolatile antifuse technology, distinguishing it from SRAM-based FPGAs.

Replacement Considerations

Direct replacements within the same package and pinout include other members of the SX-A family such as the A54SX16A-TQG144A or A54SX32A-TQG144A, provided the increased logic resources are acceptable. Non-automotive grades like the standard A54SX08 variants may fit physically but lack the guaranteed extended temperature performance.
