• Interface bridging between disparate digital protocols
• Custom logic acceleration in embedded systems

Field Programmable Gate Array Procurement Notes

Verify the specific manufacturer source document for the exact pinout configuration and electrical characteristics, as distributor listings may vary. Confirm that the PLCC package variant matches the design footprint requirements. Check for RoHS compliance status if required by current assembly standards, noting historical production data indicates non-compliance for this specific legacy part number.

Field Programmable Gate Array Selection Notes

Select this component when a moderate gate count FPGA with a standard PLCC package is required for prototyping or legacy maintenance. Ensure the design accommodates the 4.5V to 5.5V supply voltage requirement. Consider the 0°C to 70°C operating temperature range against environmental conditions. Verify that the 69 available I/O pins meet the interface density needs of the target application.

Field Programmable Gate Array Part Context

This device belongs to the Microsemi ACT3 family of FPGAs, designed for applications requiring high predictability and ease of integration. The ACT3 series utilizes SRAM-based technology, allowing for reprogrammability. The A1425A variant specifically offers 2,500 gates, positioning it as a mid-range solution within the accelerator series for complex logic implementations.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status of this product line, direct pin-to-pin replacements from the same manufacturer are not listed. Designers should evaluate modern FPGA families from Microchip or other vendors, ensuring compatibility with existing software tools and physical constraints.
