A54SX16-CQ208M

Overview

The A54SX16-CQ208M is a nonvolatile Field Programmable Gate Array manufactured by Microsemi Corporation. It features 1452 Configurable Logic Blocks and an equivalent of 16,000 system gates. The device operates with a maximum clock frequency of 205 MHz and exhibits a maximum combinational delay of 1 ns per CLB. It utilizes a ceramic CQFP-256 package containing 256 terminals. The component supports mixed-voltage I/O operation at 2.5 V, 3.3 V, and 5 V levels, with a rated supply voltage of 2.5 V.

Feature Summary

• Nonvolatile single-chip FPGA solution eliminating external configuration memory requirements
• Supports mixed-voltage I/O operation with 5 V input tolerance and drive strength
• Includes configurable dual-port SRAM for high-speed data buffering applications
• Provides deterministic timing control and up to 100% pin locking capabilities

Applications

• High-speed controller implementations
• Peripheral bus interface logic
• DSP and co-processor functions
• Address decoding circuits

Procurement Notes

Verify the specific suffix designation against official Microsemi documentation to confirm temperature grade and package material variations. Ensure that the procurement source provides valid traceability for the ceramic package construction. Confirm RoHS compliance status as historical records indicate non-compliance for certain variants within this family.

Selection Notes

Select this model when nonvolatile configuration is required to reduce system bill of materials. Consider the 205 MHz performance limit for timing closure in synchronous designs. Verify that the 256-pin ceramic package fits the available board real estate and thermal management constraints compared to plastic alternatives.

Part Context

This component belongs to the SX-A family of FPGAs, which are designed as cost-effective ASIC alternatives. The family integrates high-performance logic with nonvolatile storage on a single chip. It serves as a consolidation solution for designs previously requiring multiple PALs, CPLDs, or volatile FPGAs with external configuration devices.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the SX-A family based on gate count and package compatibility.
