A54SX16P-PQ208M

Overview

The A54SX16P-PQ208M is a nonvolatile Field Programmable Gate Array from the Actel SX-A family, manufactured by Microchip Technology. It utilizes 0.22 μm / 0.25 μm CMOS antifuse technology and provides 24,000 system gates. The device features 1,452 configurable logic blocks (CLBs) and up to 175 user-programmable I/O pins within a 208-pin Plastic Quad Flat Pack (PQFP) package. It supports mixed-voltage operation at 2.5 V, 3.3 V, and 5 V with 5 V input tolerance. The architecture delivers 250 MHz system performance and 350 MHz internal clock speeds.

Feature Summary

• Nonvolatile single-chip solution using metal-to-metal programmable antifuse interconnect elements for permanent configuration without external memory.
• Supports hot-swap compliant I/Os allowing insertion into active systems without power sequencing requirements for supply voltages.
• Includes dedicated boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for in-system diagnostic verification.
• Features deterministic timing through unique local routing resources such as DirectConnect and FastConnect for predictable signal propagation.

Applications

• High-speed controllers and address decoding
• Peripheral bus interfaces including PCI compliance
• DSP and co-processor functions

Procurement Notes

Verify component authenticity and datasheet revision status before integration. Confirm that the specific speed grade suffix matches design timing requirements. Check for end-of-life notifications or discontinuance updates from the manufacturer. Ensure environmental compliance documentation aligns with project specifications.

Selection Notes

Select this model when a nonvolatile FPGA with high-performance antifuse technology is required. Consider the 208-pin PQFP package constraints for PCB layout. Evaluate the 175 available user I/Os against interface needs. Verify that the 2.5 V core voltage and mixed-voltage I/O capabilities match the system power rails.

Part Context

This component belongs to the Actel SX-A family of FPGAs, which are designed for cost-effective, low-power, and high-performance applications. The family integrates logic previously found in multiple CPLDs and gate arrays onto a single chip, utilizing patented antifuse technology to reduce time-to-market.
