A54SX16A-2TQG100I

Overview

The A54SX16A-2TQG100I is a Field Programmable Gate Array from the Actel SX-A family, featuring 24,000 system gates and 1,452 logic modules. It operates with a maximum system frequency of 250 MHz and an internal performance speed of 350 MHz. The device utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and supports mixed-voltage I/O standards including 2.5 V, 3.3 V, and 5 V. It provides up to 81 user-programmable I/Os in a 100-pin Thin Quad Flat Pack (TQFP) package. The component is rated for industrial temperature ranges (-40°C to +85°C) and includes features such as hot-swap compliant I/Os, boundary-scan testing compliance with IEEE 1149.1, and Actel Secure Programming Technology.

Feature Summary

• Supports mixed-voltage operation with configurable I/O standards for 2.5 V, 3.3 V, and 5 V systems.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated clock resources with hardwired HCLK and routed CLKA/CLKB networks for deterministic timing.
• Provides nonvolatile antifuse architecture with FuseLock security to prevent reverse engineering.

Applications

• High-performance digital signal processing requiring low-latency interconnects
• Industrial control systems necessitating mixed-voltage interface compatibility
• Secure embedded applications utilizing nonvolatile configuration and anti-tamper features

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type, speed grade, and temperature range. Ensure that the required I/O voltage levels and pin counts align with the design specifications before finalizing procurement orders.

Selection Notes

Select this model when 24,000 system gates are sufficient for the target logic density. The -2 speed grade offers approximately 25% faster performance than the standard grade. Confirm that the 100-pin TQFP package fits the available PCB footprint and thermal constraints for the intended operating environment.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are characterized by their metal-to-metal programmable antifuse interconnect technology. The family spans various gate counts from 12,000 to 108,000 system gates, offering a scalable solution for high-speed, low-power designs across commercial, industrial, and military temperature grades.

Replacement Considerations

Check for updated Microchip Technology part numbers within the same SX-A series or compatible legacy Actel FPGA families. Verify pinout compatibility and logical resource equivalence if substituting with other devices in the A54SX16A variant list.
