A54SX08A-TQG100A

Overview

The A54SX08A-TQG100A 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 12,000 system gates and 768 logic modules. The device supports up to 81 user-programmable I/O pins in a 100-pin Thin Quad Flat Pack (TQFP) package. It operates within an extended temperature range of -40°C to +125°C and utilizes a 0.22µ CMOS process technology. Internal performance reaches up to 250 MHz, with hardwired clock networks ensuring deterministic timing.

Feature Summary

• Automotive-grade reliability designed for harsh environments with operation from -40°C to +125°C
• Nonvolatile antifuse architecture providing inherent security against reverse engineering
• Hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing
• Integrated Silicon Explorer II diagnostic capability for real-time internal node observation

Applications

• In-cabin telematics systems
• Automobile interconnect applications
• Multiphysics micro-measurers for downhole drilling environments

Procurement Notes

Verify that the specific ordering suffix matches the required package type and lead-free status. Confirm the temperature grade aligns with the application's thermal requirements. Ensure the design tool version supports the SX-A family for proper configuration. Check for any recent Product Change Notifications regarding assembly or material updates.

Selection Notes

Select this component when nonvolatile storage and high-speed logic are required in a single chip. The TQFP-100 package offers a balance of pin count and board space. Consider the 250 MHz internal performance for complex state machines. Verify that the 81 available I/Os meet the interface requirements for the target system.

Part Context

This part belongs to the Actel SX-A Automotive Family, which was acquired by Microchip Technology. The SX-A series is known for its fine-grained sea-of-modules architecture and antifuse programming technology. It serves as a drop-in replacement for complex CPLDs in automotive and industrial applications requiring robust logic control.

Replacement Considerations

Direct replacements include other members of the SX-A family such as the A54SX16A or A54SX32A if higher gate counts are needed. For different packages, the A54SX08A-PQ208I offers more I/Os in a PQFP format. Cross-family migration to newer Microchip FPGA families requires significant design re-verification.
