• Provides extensive external connectivity through 69 available I/O pins
• Operates reliably across wide industrial temperature variations

Field Programmable Gate Array Applications

• Industrial control systems requiring programmable logic
• Embedded signal processing applications
• Custom interface adapters for legacy or specialized hardware
• Prototyping of digital circuits before ASIC fabrication

Field Programmable Gate Array Procurement Notes

Verify the exact suffix against official Microsemi documentation, as standard listings often specify 'A1020B-1VQG80I'. Confirm that the requested part number corresponds to the correct package type and temperature grade. Check for obsolescence status, as this product family has been subject to discontinuation notices. Ensure compatibility with existing programming tools and verify moisture sensitivity level requirements for storage and handling.

Field Programmable Gate Array Selection Notes

Select this component when a moderate gate count FPGA is required for cost-effective prototyping. Compare against the A1010B series if lower logic density suffices. Consider the VQFP package constraints regarding board space and thermal dissipation. Verify that the 5.5V maximum supply voltage aligns with the system power rails. Evaluate alternative packages like PLCC if leaded soldering is preferred over surface mount technology.

Field Programmable Gate Array Part Context

This device is part of the ACT™ 1 family, which represents an earlier generation of Flash-based FPGAs from Microsemi. These devices are characterized by their non-volatile configuration memory, allowing immediate operation upon power-up without external configuration chips. The family was widely used in embedded applications prior to the transition toward more advanced high-performance FPGA architectures.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided data. Due to the discontinued status of the ACT™ 1 series, no official cross-reference is listed. Designers may need to evaluate modern FPGA families from Microchip or other manufacturers, requiring significant schematic and firmware redesign.
