A54SX16A-1TQ100M

Overview

The A54SX16A-1TQ100M is a nonvolatile Field Programmable Gate Array from the Microchip Technology SX-A family, featuring 24,000 system gates and 81 user-programmable I/Os. It operates within a supply voltage range of 2.25 V to 2.75 V at a nominal 2.5 V. The device supports a maximum system performance frequency of 263 MHz with an internal clock capability up to 350 MHz. Packaged in a 100-pin Thin Quad Flat Pack (TQFP), it is rated for military temperature grades spanning -55°C to +125°C.

Feature Summary

• Utilizes metal-to-metal programmable antifuse technology for permanent, low-impedance interconnections that resist reverse engineering.
• Supports hot-swap operations and mixed-voltage I/O standards including 3.3 V PCI, 5 V TTL, and 2.5 V LVCMOS2 without power sequencing requirements.
• Integrates dedicated boundary-scan testing compliant with IEEE Standard 1149.1 (JTAG) for superior diagnostic capabilities.

Applications

• High-performance logic integration requiring deterministic timing and fast execution of complex functions
• Systems demanding secure, nonvolatile single-chip solutions with protection against design theft
• Industrial or military applications requiring operation across extended temperature ranges (-55°C to +125°C)

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors. Confirm the specific ordering suffix matches the required speed grade, package type, and military temperature rating. Ensure compliance with export regulations such as ITAR or EAR if applicable to the destination region.

Selection Notes

Select this part for designs needing 24,000 system gates with 81 I/Os in a compact 100-pin TQFP footprint. The '1' indicates a speed grade approximately 15% faster than standard, while 'M' specifies military temperature coverage. Verify that the 2.5 V core voltage aligns with the target system's power architecture.

Part Context

This component belongs to the Actel SX-A FPGA family, originally developed by Actel Corporation and now manufactured by Microchip Technology. The SX-A series is characterized by its high-density antifuse architecture, offering a cost-effective alternative to gate arrays for high-speed digital logic implementations.

Replacement Considerations

Direct replacements within the same package and pinout include other speed grades of the A54SX16A series, such as A54SX16A-TQ100M or A54SX16A-2TQ100M. Cross-family migration to newer Microchip FPGA architectures requires schematic and software redesign due to architectural differences.
