A54SX16P-2PQG208I

Overview

The A54SX16P-2PQG208I is an industrial-grade antifuse FPGA from the Actel SX-A family, housed in a 208-pin PQFP package. It provides 24,000 system gates and supports up to 175 user I/Os. The device operates at a standard supply voltage of 3.3 V with a range of 3.135 V to 3.465 V. It achieves a maximum system performance frequency of 250 MHz and an internal clock speed of 350 MHz. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation including 2.5 V, 3.3 V, and 5 V I/O standards with 5 V input tolerance.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes dedicated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG).
• Utilizes nonvolatile antifuse technology for deterministic timing and inherent design security.

Applications

• High-speed data path logic and fast counters requiring deterministic timing.
• PCI-compliant interface designs supporting 66 MHz operations.
• Industrial control systems requiring robust hot-swap capabilities.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, speed grade, and temperature rating. Confirm current availability status as legacy products may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints and programming tools before procurement.

Selection Notes

Select this model for applications requiring high-performance logic density within a PQFP form factor. Consider the 250 MHz system speed for complex state machines. Verify that the 3.3 V operating voltage aligns with the target system's power rails and I/O requirements.
