A54SX08-2PQ208

Overview

The A54SX08-2PQ208 is a nonvolatile FPGA from the SX-A family, fabricated on 0.22 μm / 0.25 μm CMOS antifuse technology. It provides 12,000 system gates, 768 logic modules, and 130 maximum user I/Os in a 208-pin PQFP package. The device supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. Speed grade -2 offers approximately 25% faster performance than standard speed. It features hot-swap compliant I/Os (excluding 3.3 V PCI), boundary-scan testing compliance with IEEE 1149.1, and Actel Secure Programming Technology.

Feature Summary

• Supports mixed-voltage operation for 2.5 V, 3.3 V, and 5 V I/Os with 5 V drive strength
• Features hot-swap compliant I/Os allowing safe insertion into active systems
• Includes Actel FuseLock security to prevent reverse engineering and design theft
• Provides deterministic timing through metal-to-metal programmable antifuse interconnect

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces including 66 MHz PCI compliant designs
• DSP and co-processor functions
• Single-chip ASIC alternatives requiring high reliability

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm temperature grade and packaging type. The base model designation indicates the gate count and package style, but additional characters define critical operational parameters such as industrial or commercial temperature ranges. Ensure compatibility with existing design tools and verify that the antifuse technology meets long-term availability requirements for the intended application lifecycle.

Selection Notes

Select this component when a nonvolatile single-chip solution is required without external configuration memory. The SX-A architecture allows 100% resource utilization and pin locking, facilitating concurrent PCB development. Consider the -2 speed grade if higher internal clock frequencies are needed compared to standard speed devices. Verify that the 208-pin PQFP package dimensions fit the target board layout and thermal constraints.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilizes patented metal-to-metal antifuse technology for permanent programming. The family includes devices ranging from 12,000 to 108,000 system gates. The A54SX08 variant represents the entry-level capacity within this series, offering a balance of logic density and I/O flexibility for cost-sensitive applications.
