A54SX16-1CQ208B

Overview

The A54SX16-1CQ208B is a Field Programmable Gate Array (FPGA) belonging to the Microsemi SX family. It features 1452 Configurable Logic Blocks (CLBs) and an equivalent of 16,000 system gates. The device operates with a maximum clock frequency of 205 MHz and exhibits a CLB-maximum combinational delay of 1 ns. It utilizes a ceramic CQFP-256 package with 256 terminals. The component supports mixed-voltage operation for core and I/Os, including PCI-compliant interfaces. The standard supply voltage is 3.3 V, with a specified operating temperature range extending up to 70 °C.

Feature Summary

• High-density logic architecture providing 1452 CLBs and 16,000 system gates within a single chip.
• Supports mixed-voltage operation allowing flexible integration of 5.0V or 3.3V core and I/O standards.
• Includes fast wide-decode circuitry capable of 7.5 ns 35-bit address decoding.
• Offers high performance with a 205 MHz clock frequency and 1 ns combinational delay.

Applications

• Complex digital logic replacement in industrial control systems
• Prototyping and development of custom ASIC designs
• Signal processing applications requiring fast address decode capabilities

Procurement Notes

Verify the specific suffix 'B' against official Microsemi documentation to confirm exact material composition and manufacturing lot specifications. Ensure compatibility with existing PCB footprints for the CQFP-256 ceramic package. Confirm that the 70 °C commercial temperature rating meets the operational requirements of the target environment before procurement.

Selection Notes

Select this component when a high gate count FPGA is required in a ceramic package for enhanced durability. The 205 MHz speed grade is suitable for moderate-speed synchronous logic. Consider the 16,000 gate capacity relative to design complexity. Verify that the 256-pin form factor fits the mechanical constraints of the assembly.

Part Context

This part belongs to the Microsemi SX family of FPGAs, designed as a high-capacity single-chip ASIC alternative. The family typically offers resources ranging from 3,000 to over 50,000 system gates. The SX series is characterized by its CMOS technology and support for both commercial and military-grade packaging options.

Replacement Considerations

Direct replacements include other variants within the A54SX16 family, such as the A54SX16-1PQG208 for plastic packages or the A54SX16-CQ256 for different pin counts. Cross-family migration to the A54SX32A may be necessary if higher logic density is required.
