A54SX32A-TQG100M

Overview

The A54SX32A-TQG100M is a field-programmable gate array from the Microchip SX-A family, featuring 48,000 system gates and 2,880 logic modules. It operates within a voltage range of 2.25 V to 2.75 V at a nominal 2.5 V. The device provides 81 user I/Os in a TQFP-100 package and supports a maximum operating frequency of 278 MHz. It functions across an extended temperature range of -55°C to +125°C.

Feature Summary

• Utilizes metal-to-metal programmable antifuse technology for permanent configuration without volatile bitstreams.
• Supports hot-swap capabilities allowing safe insertion into active systems with configurable power-up states.
• Includes dedicated routing resources like DirectConnect and FastConnect for deterministic signal propagation.
• Integrates IEEE 1149.1 compliant boundary-scan testing via JTAG interface.

Applications

• High-performance digital logic integration requiring nonvolatile single-chip solutions
• Systems demanding hot-swappable FPGA interfaces with mixed-voltage I/O standards
• Industrial or automotive applications requiring extended temperature operation (-55°C to +125°C)

Procurement Notes

Verify the specific suffix 'M' against official documentation to confirm military-grade qualification status. Ensure compliance with export regulations such as ITAR or EAR if applicable. Confirm that the TQFP-100 package matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when 48K system gates and 81 I/Os are required in a thin quad flat pack. The -M suffix indicates suitability for extreme environments up to +125°C. Compare against standard speed grades if lower timing constraints suffice, noting that this unit targets high-frequency performance.

Part Context

This part belongs to the Actel SX-A series, known for its sea-of-modules architecture. It sits between the A54SX16A and A54SX72A in terms of capacity. The TQG100 designation specifies the Thin Quad Flat Pack package with 100 pins and Military temperature grade.

Replacement Considerations

Direct replacements include other A54SX32A variants with different packages (e.g., FGG256) or speed grades. Verify pin compatibility and thermal characteristics when substituting. No direct cross-brand equivalents exist due to unique antifuse architecture.

FAQ

What is the significance of the 'M' suffix in A54SX32A-TQG100M?

The 'M' suffix denotes the Military temperature grade, indicating the device is qualified to operate reliably within the extended range of -55°C to +125°C.

Does the A54SX32A support hot-swapping?

Yes, the SX-A family I/Os are configured to be hot-swappable, allowing the device to be plugged into an electrically active system without causing damage or degrading reliability.

How does the SX-A architecture ensure security?

Security is ensured through Actel's FuseLock technology and the inherent difficulty of distinguishing programmed from unprogrammed antifuses, preventing reverse engineering and design theft.
