A54SX32A-2TQ100

Overview

The A54SX32A-2TQ100 is a Field Programmable Gate Array from the 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-programmable I/O pins in a 100-pin Thin Quad Flat Pack (TQFP) package. It supports a maximum operating frequency of 278 MHz and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports hot-swap capabilities for safe insertion into active systems without power sequencing requirements.
• Features deterministic timing with user-controllable delays and 100% pin-locking resource utilization.
• Includes IEEE 1149.1 compliant boundary-scan testing for enhanced diagnostic and verification capabilities.

Applications

• High-performance digital signal processing
• Industrial control systems requiring deterministic timing
• Secure embedded applications utilizing antifuse technology

Procurement Notes

Verify the specific speed grade suffix '2' against current Microchip Technology documentation to confirm performance characteristics. Ensure the TQFP-100 package availability aligns with project timelines, as lead times may vary based on manufacturing status. Confirm RoHS compliance details if environmental regulations apply to the final assembly.

Selection Notes

Select this component when 48,000 system gates and 81 I/Os are required in a compact 100-pin form factor. The -2 speed grade offers approximately 25% faster performance than standard grades. Verify that the 2.5 V core voltage and mixed-voltage I/O options match the target system's power architecture and interface standards.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes nonvolatile antifuse technology. The SX-A series is designed for low-power, high-performance applications where security and deterministic timing are critical. The A54SX32A variant specifically targets designs needing moderate logic density with robust I/O flexibility.

Replacement Considerations

Check for updated speed grades or package options within the A54SX32A series. Consult Microchip Technology for any discontinued variants or recommended upgrades that maintain the same pin count and gate density while offering improved performance or availability.
