A14100A-1CQ256B

Field Programmable Gate Array Overview

The A14100A-1CQ256B is a high-performance Field Programmable Gate Array (FPGA) from Microsemi's ACT3 Accelerator Series. It features 1377 Configurable Logic Blocks (CLBs) and approximately 20,000 system gates, delivering deterministic timing with clock-to-output delays as low as 9.0 ns for the -1 speed grade. The device supports up to 186 MHz on-chip performance and includes four fast, low-skew clock networks. Packaged in a 256-pin Ceramic Quad Flat Package (CQFP), it operates within a supply voltage range of 4.5V to 5.5V.

Field Programmable Gate Array Feature Summary

• ACT3 architecture provides highly predictable performance through 100% automatic place-and-route capabilities.
• Includes dedicated hardware accumulators and loadable counters for efficient datapath processing.
• Supports mixed-voltage operation with PCI-compliant I/O standards.

Field Programmable Gate Array Applications

• High-speed digital signal processing
• Complex state machine implementations
• Protocol conversion and interface bridging

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'B' against official Microsemi documentation to confirm package material and temperature rating. Confirm end-of-life status and lead times directly with authorized distributors or Microsemi, as availability for legacy ACT3 devices varies significantly across the supply chain.

Field Programmable Gate Array Selection Notes

Select this component when deterministic timing and high gate density are required in a CQFP form factor. Compare CLB counts and I/O pin availability against alternative ACT3 variants like the A1425A to ensure sufficient logic resources for the target design complexity.

Field Programmable Gate Array Part Context

This part belongs to the ACT3 Accelerator Series, designed as a single-chip ASIC alternative. It bridges the gap between standard PLDs and complex FPGAs, offering fixed-function hardware blocks alongside programmable logic for optimized area and speed.

Field Programmable Gate Array Replacement Considerations

Direct replacements include other ACT3 family members such as the A1425A-1CQ256B or A1440A, provided pin compatibility and logic capacity meet requirements. Verify that any substitute maintains the same ceramic package and electrical specifications.
