A54SX32A-TQ100A

Overview

The A54SX32A-TQ100A 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 48,000 system gates and 2,880 logic modules. The device supports up to 81 user-programmable I/Os 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 250 MHz, with deterministic timing and hot-swap compliant I/Os.

Feature Summary

• Automotive-grade reliability with extended temperature operation (-40°C to +125°C)
• Sea-of-modules architecture enabling 100% resource utilization and pin locking
• Hot-swap compliant I/Os allowing safe insertion without power sequencing
• Built-in Boundary Scan Testing (BST) compliant with IEEE 1149.1

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compliance with export administration regulations if applicable. Confirm RoHS status and packaging details directly with the manufacturer or authorized distributors prior to procurement.

Selection Notes

Select this component for designs requiring automotive qualification and high-density programmable logic in a compact TQFP-100 footprint. Consider the 48,000 system gate capacity and 250 MHz internal performance for complex state machines and datapath logic. Verify I/O voltage requirements match the configurable 3.3V PCI, LVTTL, or 2.5V LVCMOS2 standards.

Part Context

This part belongs to the Actel SX-A Automotive Family FPGAs, which are nonvolatile antifuse-based devices. The SX-A series simplifies design time and reduces power consumption compared to previous generations. It serves as a single-chip solution replacing multiple CPLDs, offering secure programming via FuseLock technology to prevent reverse engineering.

Replacement Considerations

Consult the official SX-A Family datasheet for alternative packages such as FBGA or PQFP variants within the same gate density. Cross-reference speed grades and temperature ranges when selecting equivalent parts from the broader SX-A portfolio.
