A54SX16-1VQ100

Overview

The A54SX16-1VQ100 is a Field Programmable Gate Array from the Actel SX-A family, featuring 24,000 system gates and 81 user I/Os. It operates within a voltage range of 2.25 V to 2.75 V at a nominal 2.5 V, supporting a maximum frequency of 250 MHz with an internal performance of 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and is housed in a 100-pin Thin Quad Flat Pack (TQFP) package. Designed for commercial applications, it functions reliably between 0°C and +70°C.

Feature Summary

• Supports mixed-voltage operation across 2.5 V, 3.3 V, and 5 V domains with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Provides deterministic timing through patented metal-to-metal antifuse interconnects and dedicated routing resources.
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).

Applications

• Integration of 66 MHz PCI compliant logic solutions
• High-performance state machines and fast counters
• Data path logic requiring deterministic timing

Procurement Notes

Verify component authenticity by checking markings against official datasheet specifications. Confirm package type and speed grade suffixes match design requirements. Ensure storage conditions comply with moisture sensitivity levels prior to soldering. Review end-of-life notifications as availability may be restricted.

Selection Notes

Select this model for designs requiring nonvolatile single-chip FPGA solutions with high-speed performance. Verify that the 100-pin TQFP package fits the PCB layout constraints. Ensure the 2.5 V core voltage aligns with the system power architecture. Consider the -1 speed grade if faster performance than standard is required.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are fabricated using antifuse technology. The family includes devices ranging from 8,000 to 108,000 system gates. The SX-A series is known for its sea-of-modules architecture and low-power consumption characteristics suitable for embedded applications.

Replacement Considerations

Check for updated Microchip Technology equivalents or other antifuse-based FPGAs with similar gate counts and pin compatibility. Verify electrical specifications and package dimensions before substitution.
