A54SX16-1CQ208M

Overview

The A54SX16-1CQ208M is a high-performance System-on-a-Chip FPGA from the SmartFusion family, integrating an ARM Cortex-M3 processor with Flash-based FPGA fabric. It features 16K logic gates and supports up to 1.2 Gbps serial transceivers. The device includes embedded memory blocks and analog peripherals for mixed-signal applications. Operating at speeds up to 100 MHz, it offers low power consumption and non-volatile configuration storage. The CQFP-208 package provides extensive I/O connectivity for industrial and aerospace designs.

Feature Summary

• Integrates a hardened ARM Cortex-M3 processor with Flash-based FPGA fabric for secure, low-power system integration
• Provides embedded analog peripherals including ADCs and DACs for direct sensor interfacing without external components
• Features non-volatile Flash technology enabling instant-on operation and robust radiation tolerance for harsh environments

Applications

• Industrial automation controllers requiring deterministic real-time processing
• Aerospace and defense avionics systems needing radiation-hardened solutions
• Medical imaging devices utilizing embedded analog-to-digital conversion capabilities
• Secure communication gateways leveraging hardware-level encryption engines

Procurement Notes

Verify the specific suffix codes against official Microsemi documentation to confirm temperature range and packaging details. Ensure compatibility with legacy programming tools when upgrading from previous generation devices. Confirm supply chain authenticity through authorized distributors to avoid counterfeit components in safety-critical applications.

Selection Notes

Evaluate the total logic resource requirements against the 16K gate capacity to ensure sufficient headroom for design complexity. Consider the available GPIO count and serial transceiver bandwidth relative to interface demands. Assess power budget constraints given the integrated processor and FPGA activity levels during peak operation cycles.

Part Context

This component belongs to the SmartFusion family, which bridges the gap between microcontrollers and FPGAs by combining both technologies on a single die. It targets applications requiring high reliability and security, distinguishing itself from standard SRAM-based FPGAs through its inherent non-volatility and hardened processor core.

Replacement Considerations

Direct replacements include other members of the SmartFusion family such as the A54SX series with varying logic densities. Cross-reference pinouts and electrical characteristics carefully when considering migration to newer Microchip Technology equivalents following the acquisition.
