A54SX16A-1TQG100M

Overview

The A54SX16A-1TQG100M is a Field Programmable Gate Array from the Microchip Technology SX-A family, featuring 24,000 system gates and 81 user-programmable I/O pins. It operates within a supply voltage range of 2.25 V to 2.75 V, with a nominal operating voltage of 2.5 V. The device supports a maximum system performance frequency of 263 MHz and an internal performance specification of 350 MHz. It is housed in a TQFP-100 surface-mount package and is rated for an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance and drive strength.
• Features hot-swap compliant I/Os that allow safe insertion into active systems without power sequencing requirements.
• Includes individually configurable output slew rate control and power-up pull-up or pull-down resistors.

Applications

• Digital signal processing implementations
• PCI-compliant interface designs
• State machine logic integration

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm the specific ordering suffix matches the required speed grade and temperature rating. Check for RoHS compliance status as indicated by the 'G' suffix if applicable. Ensure the package type corresponds to the design footprint requirements.

Selection Notes

Select this model for applications requiring deterministic timing and high-speed logic processing within the SX-A architecture. Consider the 263 MHz system speed grade for performance needs exceeding standard rates. Verify that the 81 available I/O pins meet the interface count requirements for the target design.

Part Context

This component belongs to the Actel SX-A FPGA family, which utilizes nonvolatile antifuse technology. The series provides single-chip solutions with high reliability and security features, including FuseLock protection against reverse engineering. It serves as a platform for integrating complex logic functions previously handled by multiple CPLDs.

Replacement Considerations

Consult official Microchip documentation for verified cross-reference part numbers. Ensure any substitute maintains compatibility with the TQFP-100 package and meets the required electrical specifications.
