A54SX16A-TQG100I

Overview

The A54SX16A-TQG100I is a Field Programmable Gate Array from the Actel SX-A family, featuring 24,000 system gates and 81 user-programmable I/Os. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology to provide deterministic performance with up to 250 MHz system speed and 350 MHz internal clock frequency. The device operates within a voltage range of 2.25 V to 2.75 V at a nominal 2.5 V. Packaged in a 100-pin Thin Quad Flat Pack (TQFP), it supports industrial temperature grades ranging from -40°C to +85°C.

Feature Summary

• Supports hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Features nonvolatile antifuse architecture that prevents reverse engineering and eliminates configuration bitstream interception risks.
• Provides mixed-voltage operation capabilities supporting 2.5 V, 3.3 V, and 5 V standards with 5 V input tolerance.

Applications

• High-performance logic integration replacing complex programmable logic devices (CPLDs).
• Gate array applications requiring deterministic timing and fast execution of complex logic functions.
• Systems requiring secure programming and protection against design theft via FuseLock technology.

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct channels. Confirm RoHS compliance status and specific package markings against official datasheets. Check for end-of-life notifications or obsolescence notices prior to procurement planning.

Selection Notes

Select this model for designs requiring 24,000 system gates with an industrial temperature rating. Ensure the application fits within the 81 available I/O constraints. Verify that the 2.5 V core voltage aligns with the system power supply architecture.

Part Context

This part belongs to the Actel SX-A FPGA family, which offers high-density logic resources on a single chip. The SX-A series is known for its metal-to-metal antifuse interconnects, providing low capacitance and resistance for superior signal propagation speeds compared to standard SRAM-based FPGAs.

Replacement Considerations

Direct pin-compatible replacements are not explicitly listed in public documentation. Consider other members of the A54SX16A series with different speed grades or packages if functional equivalence is required.
