A54SX08A-TQG100

Overview

The A54SX08A-TQG100 is a nonvolatile FPGA from the SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 system gates, 768 logic modules (comprising 512 dedicated flip-flops), and supports up to 81 user I/Os in the 100-pin TQFP package. The device operates within a supply voltage range of 2.25 V to 5.25 V and functions across an industrial temperature range of -40°C to +85°C. It features three global clock networks and supports mixed-voltage I/O standards including 3.3 V PCI, 5 V TTL, and 2.5 V LVCMOS.

Feature Summary

• Supports hot-swap operations with configurable power-up resistors for deterministic initialization without supply sequencing requirements.
• Features Actel Secure Programming Technology with FuseLock to prevent reverse engineering and unauthorized design access.
• Includes Boundary-Scan Testing compliant with IEEE Standard 1149.1 for superior diagnostic and verification capabilities.

Applications

• Industrial control systems requiring deterministic timing and high reliability
• Embedded applications needing single-chip nonvolatile configuration solutions
• Systems utilizing mixed-voltage interfaces such as 3.3 V or 5 V PCI and TTL

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, speed grade, and temperature rating. Confirm RoHS compliance status and packaging details directly with authorized distributors or the manufacturer prior to purchase.

Selection Notes

Select this component for designs requiring nonvolatile logic with fast internal routing via DirectConnect and FastConnect resources. Ensure the 100-pin TQFP footprint aligns with PCB constraints and that the 81 available I/O pins satisfy interface requirements.

Part Context

This part belongs to the Microchip SX-A family of FPGAs, originally developed by Actel Corporation. The series utilizes metal-to-metal programmable antifuse interconnect elements to provide permanent low-impedance connections between logic modules.

Replacement Considerations

Consult official cross-reference data for verified substitutes. Verify pin compatibility and electrical specifications before replacing existing components in established designs.
