A1020B-PL44I

Field Programmable Gate Array Overview

The A1020B-PL44I is an embedded Field Programmable Gate Array (FPGA) from the Microsemi ACT™ 1 series. It features a logic density of 2000 equivalent gates organized into 547 Configurable Logic Blocks (CLBs). The device provides 34 available I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 44-pin PLCC package with J-leads, designed for surface-mount installation. The component supports a commercial operating temperature range of 0°C to 70°C.

Field Programmable Gate Array Feature Summary

• ACT™ 1 architecture providing 2000 equivalent gates and 547 CLBs
• 44-pin Plastic Leadless Chip Carrier (PLCC) surface-mount package
• Single 5V power supply operation

Field Programmable Gate Array Applications

• General-purpose digital logic prototyping
• Interface bridging between different voltage domains
• Discrete logic replacement in industrial control systems

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'PL44I' against official Microsemi documentation to confirm the package type and temperature grade. Note that this product line has been discontinued by the manufacturer. Ensure compatibility with legacy design tools and verify that the MSL rating meets assembly requirements.

Field Programmable Gate Array Selection Notes

Select this part when a low-density FPGA solution is required for simple state machines or glue logic replacement. Compare pin counts and CLB availability against the A1010B series if lower gate counts suffice. Confirm that the 44-pin PLCC footprint matches the existing PCB layout constraints.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT™ 1 family, which was succeeded by the SmartFusion and IGLOO series. The A1020B designation indicates a specific speed grade within the 2000-gate class. The 'I' suffix typically denotes the industrial temperature range, though datasheets should be consulted for precise thermal specifications.

Field Programmable Gate Array Replacement Considerations

Microchip Technology issued a Product Change Notification for the A1010B and A1020B families on June 21, 2013. No direct functional equivalents are listed in public databases; consider modern low-density FPGAs from Xilinx or Lattice for new designs.
