A54SX16-1CQ256

Overview

The A54SX16-1CQ256 is a Field Programmable Gate Array (FPGA) from the Microsemi SX family, featuring 1452 Configurable Logic Blocks (CLBs) and an equivalent of 16000 system gates. It operates with a maximum clock frequency of 205 MHz and exhibits a CLB-maximum combinational delay of 1 ns. The device utilizes CMOS technology and is housed in a Cavity-Up Ceramic QFP-256 package containing 256 terminals. It supports a supply voltage range between 2.97 V and 3.63 V, with a nominal operating voltage of 3.3 V.

Feature Summary

• Nonvolatile flash-based architecture enabling instant power-up functionality without external configuration memory.
• Configurable I/O interface supporting mixed-voltage operation including 3.3 V, 5 V TTL, and 2.5 V LVCMOS standards.
• Hot-swap compliant I/Os designed for safe insertion and removal while the system is powered.

Applications

• Industrial control systems requiring deterministic logic processing.
• Telecommunications infrastructure utilizing PCI bus interfaces.
• Military and aerospace applications demanding radiation tolerance and high reliability.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status as specific variants may differ. Ensure proper handling procedures are followed during procurement and storage to maintain device integrity prior to assembly.

Selection Notes

Select this model when a nonvolatile FPGA solution with moderate gate density is required. Verify that the 256-pin ceramic QFP package fits the target PCB layout. Ensure the design accommodates the specified 2.97 V to 3.63 V supply voltage range and thermal requirements for the commercial temperature grade.

Part Context

This component belongs to the Microsemi SX series of flash-based FPGAs, which integrate nonvolatile configuration memory directly on-chip. The SX family provides a single-chip solution for CPLD and FPGA integration, offering high resource utilization and pin locking capabilities compared to traditional volatile SRAM-based FPGAs.

Replacement Considerations

Consider the A54SX16A-FGG256A for surface-mount FBGA packaging alternatives within the same logical capacity. Verify pin compatibility and electrical specifications before substituting different package types or updated series revisions.
