A54SX08A-TQ100A

Overview

The A54SX08A-TQ100A is an antifuse-based Field Programmable Gate Array from the SX-A Automotive family, manufactured by Microchip Technology. It provides 12,000 system gates and supports up to 81 user-programmable I/O pins within a 100-pin Thin Quad Flat Pack (TQFP) package. The device operates at internal clock frequencies up to 250 MHz and is designed for automotive environments with a temperature range of -40°C to +125°C. Key electrical specifications include a supply voltage range of 2.25V to 2.75V for VCCA/VCCI. The architecture utilizes a sea-of-modules design with DirectConnect and FastConnect routing resources to minimize signal propagation delays.

Feature Summary

• Automotive-grade reliability with extended temperature support (-40°C to +125°C)
• Nonvolatile antifuse technology providing inherent security against reverse engineering
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Integrated Boundary Scan Testing (BST) compliant with IEEE Standard 1149.1

Applications

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

Procurement Notes

Verify the specific ordering suffix 'G' for lead-free packaging compliance if required by your assembly process. Confirm that the TQFP-100 package variant matches your PCB footprint requirements. Ensure that the automotive temperature grade aligns with your environmental testing standards. Check for any specific PCN updates regarding material or assembly changes before finalizing procurement.

Selection Notes

Select this component when designing for automotive environments requiring nonvolatile configuration and high-speed logic processing. The SX-A architecture offers deterministic timing and 100% pin-locking capabilities, which are critical for complex interface designs. Consider the available global and quadrant clock resources if your design requires precise clock distribution across the die.

Part Context

This part belongs to the Actel SX-A Automotive Family, which includes devices ranging from 12,000 to 108,000 system gates. The A54SX08A represents the entry-level capacity in this series, offering a balance of performance and resource density suitable for moderate complexity logic applications in harsh automotive environments.

Replacement Considerations

Direct replacements within the same package and pinout include other members of the SX-A Automotive family such as the A54SX16A or A54SX32A, provided the gate count and I/O requirements are met. Verify that the speed grade and temperature rating of the substitute match the original design specifications.
